An Archetypal Overture

The Solfachord archetype, once a novel "pet deck," has been fundamentally transformed by recent support. New cards have solved all its core weaknesses (consistency, recovery, and end-board power), elevating it into a hyper-consistent and explosive Pendulum "engine."

Because this new support lacks any restrictive locks, the archetype's primary metagame role has shifted. It now functions as a powerful, generic "bridge" to enable other top-tier strategies, most notably "Solfachord Yummy" and "Solfachord K9" builds. This guide analyzes the new core and the combos that make the entire Solfachord orchestra perform at a peak competitive level.

The New Trio: The Core Engine

Solfachord Primoa
Missing: 11688916

Solfachord Primoa

The One-Card Starter. The new heart of the deck. Its Normal Summon effect searches the power-spell "Solfachord Happiness," turning this single card into a full combo. It also provides negation protection for your other "Solfachord" effects.

Solfachord Happiness
Missing: 93481594

Solfachord Happiness

The Explosive Power-Spell. A multi-modal spell that is the deck's main payoff. Its primary effect searches any two "Solfachord" Pendulums and Special Summons one, all for the cost of a discard. Its second effect grants a *second* Pendulum Summon.

Solfachord Solfegia
Missing: 84693918

Solfachord Solfegia

The Extender & High Scale. The "perfect" Scale 9, it pairs with Primoa (Scale 0) for a full Pendulum range. It's also a vital extender that Special Summons itself from the hand for free and provides crucial recovery by summoning monsters from the GY or Extra Deck.

Key Legacy Performers

DoSolfachord Cutia
Missing: 55226153

DoSolfachord Cutia

The Core Searcher. The original starter, Cutia remains essential for searching any "Solfachord" Pendulum monster, ensuring you can always find the scale or combo piece you need. It is a primary target for "Happiness."

SolSolfachord Gracia
Missing: 91598270

SolSolfachord Gracia

The Spell/Trap Searcher & K9 Bridge. Gracia searches key Spells/Traps like "Solfachord Elegance." Critically, it is a Level 5 monster, making it the essential, searchable "bridge" into the "K9" archetype's Rank 5 plays.

The deck's new starter, Primoa, enables multiple powerful combo lines. The "New" line is archetype-focused, while the "Old" line uses generic Pendulum support.

Set the Scales

Activate Solfachord Elegance. Use its effect to place Cutia from your hand to the Extra Deck, then place Gracia (Scale 1) and Cutia (Scale 8) from your hand/Extra Deck into your Pendulum Zones.

Combo Result

From one card, you now have Primoa and Gracia on field, perfect scales set, and Cutia in the Extra Deck, ready to be Pendulum Summoned for further plays.

The Crescendo: A Multi-Disruption End Board

The swarming capability from "Solfachord Happiness" (especially the extra Pendulum Summon) allows the deck to build massive, generic negate boards. A high-roll end board can establish 9 or more disruptions, funded entirely by the Solfachord engine.

Facing the Critic

Strengths (Solved)

  • Solved Consistency: Primoa is a reliable one-card starter, and Happiness searches any scales needed.
  • Solved End Board: The extra swarm from Happiness enables massive, generic multi-negate boards.
  • Solved Recovery: Primoa and Solfegia provide recursion from the GY and Extra Deck, enabling a strong grind game.

Weaknesses

  • Normal Summon Reliant: The main "Primoa" combo still relies on the Normal Summon, though the "Diviner" line provides an alternative.
  • Floodgate Vulnerability: Highly susceptible to floodgates that restrict Pendulum or Special Summoning.
  • Key Choke Points: A well-timed negation on Primoa or Happiness can be devastating if no extenders are available.

Metagame Engine Role

  • Yummy Engine: The Solfachord engine's non-locking swarming ability is used to fund the Synchro and Link summons for "Yummy" boss monsters.
  • K9 Engine: The ability to search and Special Summon SolSolfachord Gracia (Level 5) makes the deck a hyper-consistent bridge for the "K9" Rank 5 strategy.
  • Fairy Engine: The classic Diviner of the Herald + Trias Hierarchia line is now even stronger, as Diviner's tribute effect can Special Summon Solfachord Primoa directly from the deck.

Banlist Impact

The Solfachord archetype itself is largely untouched by the TCG banlist, but key synergistic cards it relies on are affected.
