NEXUS

Executive Summary

The Endymion archetype is a highly complex and powerful Pendulum strategy centered on the generation and manipulation of Spell Counters. Its playstyle revolves around building an overwhelming board of spellcaster monsters that can place multiple negates and interruptions, creating a nearly unbreakable field. The deck is renowned for its high skill ceiling and its ability to convert simple spell activations into immense board presence, culminating in the summon of its formidable boss monster, Endymion, the Mighty Master of Magic.

The Font of Power: Spell Counters

The entire Endymion strategy is fueled by Spell Counters. Every Spell Card activated becomes a resource, placing a counter on each face-up card that can hold one. These counters are then spent to activate the powerful effects of the Endymion monsters and to Special Summon them from the Pendulum Zone. Mastering the deck means mastering the flow of these counters, ensuring that every spell played contributes to the source of all magic and the eventual lockdown of the opponent.

The Magical Citadel's Roster

The Masters of Magic

Endymion, the Mighty Master of Magic

The ultimate boss monster. Provides a powerful Spell/Trap negate and is immune to targeting and destruction while it has a Spell Counter.

Servant of Endymion

A key combo enabler. Its Pendulum Effect can Special Summon itself and another monster from the deck, starting the main combo sequence.

Reflection of Endymion

A crucial extender and disruption piece. Can bounce cards on summon and is revived by Selene on the opponent's turn for interruption.

Magister of Endymion

An extender that can Special Summon a monster from the Extra Deck or Pendulum Zone, enabling access to powerful generic monsters.

The Arcane Tomes

Spell Power Mastery

The deck's primary one-card starter. Searches for an Endymion monster and places a Spell Counter, beginning the resource loop.

Magical Citadel of Endymion

The Field Spell that acts as a bank for Spell Counters, protecting them from removal and enabling explosive turns.

Mythical Institution

A continuous spell that searches for key "Mythical Beast" engine pieces and provides additional spell counter generation.

  • Easy to Summon: Typically brought out by overlaying two Level 7 monsters (like Mighty Master) into Odd-Eyes Absolute Dragon, then linking Absolute away.

Competitive Analysis

Strengths

  • High Power Ceiling: Can create some of the most oppressive end boards in the game.
  • Resilience: Can play through some hand traps due to multiple extenders and searchers.
  • Non-Once Per Turn Effects: Several key cards lack a "once per turn" clause, allowing for explosive, non-linear combos.

Weaknesses

  • High Complexity: Difficult to pilot optimally, punishing small mistakes heavily.
  • Floodgate Vulnerability: Extremely weak to anti-spell cards like Anti-Spell Fragrance and monster floodgates like There Can Be Only One.
  • Key Choke Points: A well-timed negate on Servant of Endymion's Pendulum effect can often end the turn.

External Engines

  • Mythical Beasts: A small engine (Master Cerberus, Jackal King) that generates and uses Spell Counters, providing synergy and more combo routes.
  • Heavymetalfoes Electrumite: The deck's *actual* go-to Link-2. It is essential for generating resources, fixing scales, and triggering Pendulum effects.
  • Selene, Queen of the Master Magicians: The primary Link-3 extender that bridges plays and enables Quick-Effect disruption.

Common Traps: The "Magistus" Confusion

Card to AVOID

Endymion, the Crescent Magistus

A Note on "Endymion, the Crescent Magistus"

Players new to the archetype often see "Endymion, the Crescent Magistus" and assume it belongs in the deck. This is incorrect.

  • Lore vs. Mechanics: This card shares the "Endymion" name for lore reasons (as a younger version of the character), but it is mechanically a "Magistus" archetype card.
  • No Synergy: Its effects revolve around equipping "Magistus" monsters and recycling Equip Spells. It has zero interaction with Spell Counters, which are the entire focus of this deck.
  • Resource Negative: Summoning this card is a waste of two monsters. Those resources are critical for summoning the *actual* essential Link-2, Heavymetalfoes Electrumite, which generates advantage.

Verdict: Do not play this card in an Endymion Pendulum deck. It is a "brick" that actively hinders your strategy.

Banlist Impact

While the Endymion core remains untouched, the archetype's High support reliance on key cards like Spell Power Mastery as the primary one-card starter, Servant of Endymion for combo enabling, and Magical Citadel of Endymion for Spell Counter banking. The deck requires precise sequencing of spell activations to generate enough counters for its plays. means restrictions on generic support cards do have an impact.

Affected Synergistic Cards

Forbidden

  • Apollousa, Bow of the Goddess

Limited

  • Chicken Game
  • Anti-Spell Fragrance
  • There Can Be Only One

Meta Implications: Despite restrictions on support cards, Endymion's Moderate adaptability with the Mythical Beast engine providing alternative combo routes and the ability to use generic Spellcaster Link monsters like Selene and Heavymetalfoes Electrumite for board extension. The deck can pivot between aggressive Pendulum Summon strategies and control-oriented plays depending on the situation. allows the deck to remain viable with alternative tech choices.
