Artmage Academic Arcane Arts Acropolis
I · The Acropolis
  1. At the heart of the Artmages' artistic magic stands the Acropolis academy.
  2. There, students like Graflare, Litera, Finmel, and Medius train under the silent blessing of their Power Patron, Nerva.
  3. At the succession ceremony, Finmel was about to be chosen as the next successor.
  4. In a Theorealize vision, Medius foresaw that the ceremony would be attacked.
  5. The DoomZ raided the ceremony, and the academy's peace was violently shattered.
  6. Medius threw himself between Finmel and the raiders and was gravely wounded. At that moment the Power Patron spoke to him.
  7. Made a pseudo-successor and granted Nerva's power, Medius rose as Artmage Diactorus to protect his friends.
  8. The raiders were the DoomZ, the assault squadron of the Thunderclap Empire D.O.O.M.D.U.R.G., led by Drastea: successor of the Imprisoned God Jupiter, and Graflare's own elder brother.
  9. Graflare, once a DoomZ himself, arrived with a stolen mass-produced DoomZ system, but Medius foresaw him going berserk with it.
  10. Medius took the system into himself instead and became DoomZ Break - Diactorus. Together, he and Graflare brought down Drastea's final form, Drastrius.
  11. As Drastrius began to self-destruct, Litera's transportation magic carried everyone to her homeland, Oratorio Garden. There a corrupted ritual turned the forest's Grand Spirit into a rampaging monster.
  12. To protect the unconscious Medius, Finmel made a temporary contract with Nerva's Power Patron Beast, becoming Artmage Non-Finito.
  13. In the chaos, Junora's Power Patron Spirit opened the three sealed portals hidden in Medius's mind. Nerva, Jupiter and Junora poured into him at once, and the unstable merged god Vidolium the Unstable Power Patron of Unity took his body, unleashing the Power Patron Shades.
  14. Artmage, D.O.O.M.D.U.R.G. and Oratorio Garden called a truce and rallied around Finmel, Graflare (now DoomZ XIII Over - Graflareio, in armor that carries Drastea's consciousness) and Litera (now Elfnote Regina), with a single goal: save Medius.
  15. Finmel reached Medius deep inside Vidolium and chose to share the burden of his fate as the Gatekeeper. As the Purification Power Patron, she carried him back out as Theorealized Medius.
  16. Together, Finmel and Medius gave birth to a new Power Patron, Mediclius the Extraordinary Power Patron, and armed with the purest art, "Ars Magna", leapt into the final battle.
Who's who

Gameplay Evolution Summary

2026 Update (BLZD & CORI): The introduction of the "Shadow Trinity" pendulums and the Null Realm of Vidolia has unified the disparate Medius Lore ecosystems (Artmage, DoomZ, Elvennotes). The paradigm has shifted from hand-advantage mechanics to face-down banishment as a primary cost, unlocking mathematically oppressive end-boards.

The Divine Pantheon

Medius the Pure
Missing: 97556336

Medius the Pure

PROTAGONIST / STARTER

The absolute singularity of the deck. On Normal Summon, it searches ANY Power Patron card or Special Summons one from the Deck. Its graveyard effect grants infinite grind game potential.

Vidolium the Unstable Power Patron of Unity
Missing: 70488851

Vidolium the Unstable

APEX BOSS (LVL 12)

Requires shuffling 1 Fusion, 1 Synchro, and 1 Xyz to summon. Boasts 5000 ATK. Mandatorily banishes ALL cards in both players' Graveyards Face-Down. Unaffected by non-Power Patron monster effects.

I. The Original Deities

Artmage (Fusion)

Nerva the Power Patron of Creation
Missing: 53589300

Deity: Nerva, Patron of Creation

Rewrites any Artmage effect into "Destroy all cards your opponent controls". Bypasses targeting protection.

DoomZ (Xyz)

Jupiter the Power Patron of Destruction
Missing: 68231287

Deity: Jupiter, Patron of Destruction

Uses Equip Spells as ammunition. Destroys cards on field and floats into more resources.

Elvennotes (Synchro)

Junora the Power Patron of Tuning

Deity: Junora, Patron of Tuning

Acts as a Skill Drain for the opponent's board on Summon. Locks columns to prevent Link plays.

II. The Shadow Trinity (Pendulum Integrations)

The new Level 10 Pendulums share a terrifying cost: Banish the top 3 cards of your Deck Face-Down to destroy themselves and cheat out an Extra Deck Boss.

Nervedo the Shadebeast

Scale 1
Nervedo the Shadebeast Power Patron

Ignition: SS Nerva (Fusion).

ED Trigger: Special Summon 1 "Power Patron" or "Artmage" from Deck/ED. Solves the historic Artmage normal-summon choke point.

Jupredo the Shademachine

Scale 1
Jupredo the Shademachine Power Patron

Ignition: SS Jupiter (Xyz) & attach card from hand.

ED Trigger: Add 1 "Power Patron" or "DoomZ" Spell/Trap from Deck to Hand (Searches Vidolia or Terminus).

Junoldo the Shadespirit

Scale 1
Junoldo the Shadespirit Power Patron

Ignition: SS Junora (Synchro).

ED Trigger: Add 1 "Power Patron" or "Elvennotes" card from ED/GY to Hand. The ultimate recursion tool.

III. Divine Infrastructure

Plundered Power Patron Plane - Vidolia

Plundered Power Patron Plane - Vidolia

Field Spell
  • Consistency: Reveal ED monster, banish 1 card from hand Face-Down -> Search/SS a mentioned monster.
  • Debuff: Opponent's monsters lose 100 ATK per banished card.
  • The Lock: If Nerva, Jupiter, and Junora are on field, opponent cannot activate GY effects.
Prohibited Power Patron Portal - Terminus
1LIMITED

Prohibited Portal - Terminus

Normal Spell
  • Cost & Effect: Send 1 Power Patron from Deck/ED to GY -> Search any DARK Fairy (Medius or Darklord Ixchel).
  • Restriction: Can only attack with Power Patrons.
  • Damage Step: Banish from GY -> Banish opponent's battling monster Face-Down (bypasses protection).

Tactical Operations

The Medius 1-Card Sequence: Establishing the Trinity Lock

This devastating modern route requires only Medius the Pure (or access via Terminus) and 1 discard.

1

Initiation

Normal Summon Medius. SS Power Patron Machine Doom-Z from Deck. Link into Envoy of Pure Prayers, searching the spell Theorealize.

2

GY Manipulation

Activate Theorealize to send a 2nd Medius to GY. Revive it using tools like Theorealize Overdrive, modulating levels as needed.

3

The Shadow Assembly

Activate Shade the Obscure from hand. Pay 1000 LP to destroy a Shadow Pendulum scale. The destroyed pendulum is placed face-up in the ED, immediately triggering its effect to tutor/SS without paying the face-down banish cost.

Establishing The Lock

Cascade the ED triggers to establish Nerva, Jupiter, and Junora. Activate Vidolia. The opponent's GY is now entirely locked out. Load Terminus into your GY for Damage Step protection.

Competitive Integrations (Post-BLZD)

Darklord Pile

60-70 Cards Link/Fusion

Utilizes Terminus as a highly searchable ROTA for Darklord Ixchel. Discard Ixchel to draw 2, unbricking hands and loading the GY for Banishment of the Darklords.

Win Con: Insurmountable grind game and using Vidolium as a catastrophic late-game board wipe.

Elvennotes Engine

40 Cards Synchro Focus

Maximizes Junoldo to loop Elvennotes spells from the GY, bypassing HOPT limits. Skews ED towards Chaos Angel and Crystal Wing.

Win Con: Intense Synchro disruption dodging targeted negation via multi-layered chain blocking.

DoomZ Control

40-50 Cards Xyz Focus

Treats Jupredo explicitly as a DoomZ card. Uses it as fodder for DoomZ Break - Diactorus, triggering Jupredo in the ED to search Vidolia or Terminus.

Win Con: Rapid Xyz climbing to Varudras and aggressive board breaking.

The original modular strategy prior to the Blazing Dominion convergence.

MODULE B: Fusion (Artmage)

Action

Summon Medius -> Special Summon Artmage Patron.

Payoff

Quick-Effect Fusion into Nerva.

MODULE C: Xyz (DoomZ)

Action

Summon Medius -> Special Summon DoomZ Patron.

Payoff

Cheat out Jupiter or Diactorus.

MODULE D: Synchro (Elvennotes)

Action

Summon Medius -> Special Summon Elvennotes Patron.

Payoff

Level Modulate -> Synchro Junora.

Mastering the Convergence

The Arsenal of Convergence

Prohibitive Power Patron Purview - Vilaea

Dead-End Power Patron Realm - Viraia

Quick-Play Spell

The Resource Exchange: The "Shade" engine demands a mandatory cost: Banish the top 3 cards of your deck face-down.

Judge's Note (The Shortcut):

If Viraia is in your GY, you can banish it instead to satisfy the ENTIRE 3-card banishing cost for a Shade monster.

Theorealize Past Lull

Theorealize Past Lull

Normal Spell

The Medius Starter: Use this while controlling an Artmage, DoomZ, or Elfnote card to Special Summon Medius the Pure directly from the deck.

Power Patron Shadows of the End Times

Shadows of the End Times

Normal Trap

Special Summon any Patron from the GY or Extra Deck and banish opponent resources based on the variety of monster types you control.

Purification Power Patron

Purification Power Patron

Link-2

Requires 2 non-Link monsters. Represents Finmel transforming to save Medius.

  • Searches a "Theorealize" card if Link Summoned with a Power Patron in GY.
  • Quick-Link: During Main Phase, if you control another DARK Fairy, you can Link Summon using materials you control.
Elfnote June Pride

Elfnote June Pride

Synchro

Center Zone Strategy: While she is in the center Main Monster Zone, only center zone monsters can declare attacks.

Mass Swarm: As a Quick Effect, she can return to the ED to Special Summon 3 "Elfnote" monsters (1 each from Hand, Deck, and GY) for massive swarm potential.

Beyond the Brave: Mediclius the Extraordinary Power Patron

  • TCG · Beyond the Brave ·
  • OCG ·

Beyond the Brave gives Power Patron a Link boss that scales with its board. Mediclius the Extraordinary Power Patron is a Link-3 whose three arrows all point down, so from the Extra Monster Zone it looks at three of your Main Monster Zones. Each monster it points to unlocks another effect. The same set's Ars Magna monsters fill those zones for free: they return from banishment whenever a Link Monster is Special Summoned, and Mediclius's own Link Summon counts. The Trinity lock and the Pendulum lines in the other tabs are unchanged. This tab covers Mediclius and how it fits beside them.

It counts its arrows

One pointed monster turns on a mass negate, two make it unaffected by your opponent's activated effects, and three unlock a Quick Effect that banishes every card they control.

Triple yours, halve theirs

Its 1+ effect halves your opponent's monsters. The Finite and the Infinite triples its original ATK to 9000. A monster at 2000 ATK drops to 1000, so a single attack deals 8000.

It can arrive on their turn

Purification Power Patron can Link Summon it during your opponent's Main Phase. That Link Summon returns your banished Ars Magna monsters, so Mediclius shows up with its arrows already filled.

2+ monsters, including a Fusion, Synchro, Xyz, or Link Monster

Gains these effects based on the number of monsters it points to.

  • 1+Once per turn, during your Main Phase: You can negate the effects of all face-up monsters your opponent currently controls, also until the end of this turn, their ATK become halved.
  • 2+Unaffected by your opponent's activated effects.
  • 3Once per opponent's turn (Quick Effect): You can banish this card, also all cards your opponent controls.

A boss that's only as strong as the zones under it. Mediclius has no protection of its own until it points to two monsters, and those monsters have none at all. What makes it work in Power Patron is the Ars Magna engine: the three Ars Magna monsters Special Summon themselves from banishment when a Link Monster is Special Summoned, and you choose which zones they land in. Purification Power Patron is the standard material. As a Link-2 it counts as two, so Purification plus any one monster makes Mediclius.

Where it works

Activated effects

Mediclius is Medius awakened, ready to strike back at the Power Patrons. Its 1+ effect is word for word the Quick Effect of Artmage Finmel, the friend whose rescue started the story. Finmel needs three Monster Types on your field to use it; Mediclius needs one monster under its arrows. Early fan translations of the reveal called it "Mediacrius, the Phantom Power Patron".

Arrow Planner & Battle Math

Mediclius never touches Life Points itself: there's no cost to pay and no burn. All of its damage comes from the ATK swing. Fill the zones under it to see which effects switch on, then add the Ars Magna bonuses and your opponent's board to check whether the swing is lethal.

Fill the zones it points to

Your field · Mediclius in the left Extra Monster Zone

    Negate and halve

    Once per turn in your Main Phase: negate every face-up monster your opponent controls and halve their ATK until the end of the turn.

    Unaffected

    Your opponent's activated effects don't apply to Mediclius. The monsters under it are still exposed.

    Board banish

    Once per opponent's turn, as a Quick Effect: banish Mediclius and every card your opponent controls.

    Off

Zones 4 and 5 aren't pointed to ("Off"), so monsters there don't count. From the right Extra Monster Zone it points to zones 3, 4 and 5 instead.

  3. Their field is empty after that, but the extra attacks can only target monsters.

Lethal: 15,250 damage into 8,000 LP

The planner attacks the targets that deal the most damage first. Halving only reaches face-up monsters, and it lowers ATK, not DEF. Division and the Union's extra attacks can only target monsters, so once their field is empty Mediclius stops. The Finite and the Infinite (1000 ATK) can attack too; it isn't counted here.

Combo Lines

One opening hand, three plans: Medius the Pure plus Ars Magna the Finite and the Infinite. Every line follows the same idea: pay Ars Magna costs to banish the monsters face-up, then let a Link Summon bring them back into the zones Mediclius points to. Each step was checked against the printed text of the cards involved. Pick a line below to play through it on the board.

Line 1 · Going second

9000 ATK Breaker

Hand
Medius the Pure, Ars Magna the Finite and the Infinite
Needs
Theorealized Medius, Theorealize Overdrive and the Division and the Union in the Deck; Purification Power Patron and Mediclius in the Extra Deck
End board
Mediclius at 9000 ATK with up to 3 attacks on monsters, pointing to the Finite and the Infinite. Your opponent's face-up monsters are negated at half ATK, and one of their monsters is banished.

Why it works: both battle bonuses come from your hand after Mediclius is on the field, and the Division and the Union's revive puts a monster under it, which is all the 1+ effect needs. Watch for: only one arrow is filled, so Mediclius isn't unaffected yet. Ash Blossom on Medius's Deck summon, or Nibiru after your fifth summon, ends the line.

Line 2 · Going first

Three-Arrow Board

Hand
Medius the Pure, Ars Magna the Finite and the Infinite
Needs
Theorealized Medius, the Corruption and the Purification, the Division and the Union, Ars Magna "Citrinitas", Theorealize Past Lull and a second Medius the Pure in the Deck; Purification Power Patron and Mediclius in the Extra Deck
End board
Mediclius pointing to the Finite and the Infinite, the Corruption and the Purification and Medius the Pure, plus Citrinitas face-up: an unaffected boss, a monster banish and a Spell/Trap banish as Quick Effects, and a full-board banish on their turn

Why it works: each Ars Magna cost banishes the card face-up, so Theorealized Medius adds another Ars Magna card, and the Purification Link Summon calls the banished ones back. Citrinitas counts as an Artmage card, which turns on Theorealize Past Lull for the third monster. Watch for: Mediclius sits on the field for their whole turn, so a Kaiju can Tribute it before they make their plays.

Line 3 · Going first, pays off on their turn

Opponent's-Turn Mediclius

Hand
Medius the Pure, Ars Magna the Finite and the Infinite
Needs
The same Deck and Extra Deck cards as Line 2
End board
Your turn: Purification Power Patron, Medius the Pure, the Corruption and the Purification and Citrinitas, with the Finite and the Infinite and the Division and the Union banished. Their Main Phase: Mediclius pointing to all three Ars Magna monsters.

Why it works: Purification's Quick Effect Link Summons in either player's Main Phase while you control another DARK Fairy. That Link Summon returns both banished Ars Magna monsters, so Mediclius arrives with all three arrows filled and its board banish ready that turn. The Corruption and the Purification can banish a Spell/Trap all turn, since Purification is a Power Patron Link Monster too. Watch for: the Quick Effect only works in the Main Phase, so Infinite Impermanence on Purification in their Standby Phase stops it.

Loading the interactive combo lines…

Rules That Decide Your Turn

Extra Monster Zone only

All three arrows point down. In a Main Monster Zone they point at your Spell & Trap Zone, where monsters never go, so it has no effects there. Link Summon it to an Extra Monster Zone, not to a zone another Link Monster points to.

The count is checked live

Each tier depends on how many monsters it points to right now. Remove one of three and the board banish is gone. Remove two and it's no longer unaffected. The pointed monsters get no protection from Mediclius.

Bonuses after the summon

The Finite and the Infinite's tripled ATK and the Division and the Union's three attacks apply to the Power Patron Link Monsters you control. In our lines, you banish them from your hand only once Mediclius is on the field.

The board banish takes it too

The 3-arrow Quick Effect banishes Mediclius along with your opponent's cards. After that you no longer control a Power Patron Link Monster, so fire the Ars Magna removal effects first. Ars Magna "Philosophorum" only returns a Power Patron Link Monster from the GY, so it can't bring a banished Mediclius back.

What "unaffected" doesn't cover

It only ignores activated effects. Tributing it for a Kaiju or Lava Golem isn't an effect, so that still works. Their continuous effects still apply, and cards that negate the activation of its effect, like Solemn Strike, still negate it.

Medius the Pure isn't a Power Patron card

Theorealized Medius can only Special Summon itself from your hand if a Power Patron card is on the field, and Medius the Pure doesn't count. Use Medius's own effect to Special Summon Theorealized Medius from the Deck instead: it is always treated as a Power Patron card.

Also worth knowing: the zones Mediclius points to count as linked zones, so a face-up Pendulum Monster from your Extra Deck, such as Vidolium the Unstable Power Patron of Unity, can be Special Summoned into them.

Where It Fits

With the Ars Magna engine

The three Ars Magna monsters pay their costs by banishing themselves from your hand, then return when a Link Monster is Special Summoned. Mediclius is the Power Patron Link Monster their removal and battle effects ask for, and its own Link Summon is what brings them back. The Ars Magna guide covers the engine card by card.

With Purification Power Patron

Purification is a Link-2, so it and one more monster are all Mediclius needs. It also searches a Theorealize card when it's Link Summoned with a Power Patron monster in your GY, and its Quick Effect lets you make Mediclius on your opponent's turn. Run them together.

With the Trinity deities

Nerva, Jupiter and Junora are Fusion, Xyz and Synchro Monsters, so they can be summoned from the Extra Deck to any Main Monster Zone. When you build the lock from the Vidolia Lock tab (in the TCG the Field Spell is Plundered Power Patron Plane - Vidolia), place them in the three zones under Mediclius: the lock pieces become its three pointed monsters.

Outside Power Patron

Its materials only ask for one Fusion, Synchro, Xyz or Link Monster, so any deck that makes a Link-2 can make it, and every tier works there too. What those decks miss is the Ars Magna payoff: without the returning monsters, filling three zones under it is a lot harder.

Counterplay & Failure Modes

How opponents beat it

  • Remove what's under it. Destroying or banishing one pointed monster turns off the board banish; two turns off the immunity. Those monsters have no protection.
  • Kaiju and Lava Golem. Tributing Mediclius is part of their summon, not an activated effect, so it gets past the 2+ immunity.
  • Hand traps on the way in. Ash Blossom stops Medius's Deck summon and each Ars Magna search. Droll & Lock Bird stops every search after the first. Every line reaches five summons before Mediclius points to 2 monsters, so Nibiru, the Primal Being can still clear your field.
  • Negating Purification early. In Line 3, Infinite Impermanence on Purification during their Standby Phase stops the Quick Link Summon, because that effect only works in the Main Phase.

Mistakes to avoid

  • Summoning it to a Main Monster Zone. It points at nothing there and has no effects.
  • Board banish first, removal second. Mediclius leaves with their cards, and the Ars Magna removal effects need a Power Patron Link Monster on your field.
  • Halving too late. The 1+ effect only works in your Main Phase and only reaches face-up monsters. Use it before the Battle Phase, and use the Finite and the Infinite's banish on face-down monsters.
  • Filling the wrong zones. From the left Extra Monster Zone it reads zones 1 to 3. Returning Ars Magna monsters and Past Lull's Medius should land there.

Verdict

Mediclius is the payoff the Beyond the Brave Medius cards were built around. From Medius the Pure and one Ars Magna monster, it's a 9000 ATK breaker going second, or going first, a three-arrow board that is unaffected by your opponent's activated effects and can banish their field on their turn.

Its limit is the zones under it. Every tier depends on monsters it doesn't protect, so decks with plenty of removal, or a Kaiju, get around it. Play it as the finisher of the Ars Magna package, not as a replacement for the Trinity lock.

  • Our pick: 1 in the Extra Deck
  • Pair with 1 Purification Power Patron
  • Best with the full Ars Magna package

Critical Choke Points

  • The Threat of Droll & Lock Bird Because the entire framework demands multiple sequential searches (via Terminus, Vidolia, and Pendulums), a well-timed Droll unceremoniously terminates the turn, leaving Medius stranded.
  • Susceptibility to Nibiru Establishing the Trinity Lock takes 6-8 Special Summons. Unless you aggressively route to Artmage Diactorus (omni-negate) early, the board is highly vulnerable.
  • Preemptive GY Floodgates Despite Vidolium punishing the GY, the deck *needs* the GY for setup (Theorealize, Terminus). Dimension Shifter or Macro Cosmos effectively turns off the core engine.

Metagame Strengths

  • Absolute Immunity to Spot Removal Vidolium is unaffected by non-Power Patron monster effects. Terminus in the GY bypasses battle protection. This invalidates staples like S:P Little Knight or Mirrorjade.
  • The Non-Activating GY Lock Top tier decks (Fiendsmith, Snake-Eye, Maliss) rely on GY activations. Vidolia's lock is continuous, meaning it cannot be outed by standard monster negates like Impermanence or Veiler. Opponents must draw unsearchable backrow removal.
  • Bypassing Targeted Negation By using Shade the Obscure from the hand to trigger the Shadow Pendulums directly in the Extra Deck, you bypass on-field monster negation entirely.

Strategic Dominance (Pre-BLZD)

  • The Bridge Theory: Unlike decks locked to one mechanic, Power Patron fluidly adapts. If Artmage (Fusion) is stopped, it pivots seamlessly to DoomZ (Xyz).
  • Recursion: Medius shuffling itself back means you never run out of grind game.

Meta Considerations

  • Medius Dependency: While powerful, the deck relies heavily on resolving Medius. A well-timed Droll & Lock Bird or banishing Medius (Bystials) can halt the engine.
  • Complexity: The non-linear combo lines require high pilot skill.
