Executive Summary

The Melffy archetype is a reactive, control-based strategy that thrives on disrupting the opponent during their own turn. The deck's core mechanic revolves around its Level 2 Beast monsters returning to the hand to trigger powerful effects, such as searching, summoning, and resource recovery. This unique playstyle, best described as "your turn is my turn," subverts traditional gameplay by punishing an opponent's actions rather than preemptively negating them. While a "Pure Melffy" build is viable, the archetype's true strength is unlocked when integrated with other powerful engines like Spright and Tri-Brigade.

Typical End Board

A typical Melffy end board is not about creating a wall of negates, but rather a field of interactive threats that punish your opponent's plays. The goal is to have multiple "Melffy" monsters on the field, ready to bounce back to the hand and trigger their effects. Come and play hide-and-seek with our fluffy friends!

Competitive Analysis

Strengths

  • Resource Loop: The ability to constantly recycle resources makes the deck excel in longer, grind-based games.
  • High Ceiling with Hybrids: When combined with engines like Spright or Tri-Brigade, the deck can produce oppressive end boards.
  • Unexpected OTK Potential: Joyous Melffys allows for direct attacks, which can quickly end the game.

Weaknesses

  • Reactive Nature: Relies on the opponent to make a move, making it vulnerable to floodgates.
  • Vulnerability to Backrow: Limited in-engine ways to deal with powerful Spell and Trap cards.
  • Identifiable Choke Points: Key starters like Rescue Cat and Obedience Schooled are vulnerable to hand traps.

Live TCG Banlist Status

Banlist Impact

While the Melffy core remains untouched, the archetype's High reliance on external Beast support - the deck heavily depends on generic Beast enablers like Rescue Cat and Obedience Schooled for consistency, and benefits enormously from Spright (Level 2 synergy) and Tri-Brigade (Beast-type Link synergy) engines to achieve competitive power levels. means restrictions on generic support cards do have an impact.

Affected Synergistic Cards

Forbidden

  • Spright Elf

Limited

  • Obedience Schooled

Meta Implications: Despite restrictions on support cards, Melffy's Exceptional adaptability through hybrid builds - Melffy excels when combined with Spright (sharing Level 2 for Xyz plays) and Tri-Brigade (sharing Beast typing for Link plays). The small, self-sufficient Melffy core allows flexible ratios to accommodate multiple engines simultaneously. allows the deck to remain viable with alternative tech choices.
