Target 1 "Fusion" or "Polymerization" Normal or Quick-Play Spell in either player's GY; banish that Spell, then apply that Spell's effect when that card is activated. You can only activate 1 "Fusion Duplication" per turn.
Fusion Duplication — Power Evaluation
Final Score: 61 ± 6 · Confidence: Medium
- Intrinsic: 55 · Deck: 64 · Meta: provisional
- Primary role: Combo enabler · Secondary: Recovery/Recursion
Why it scores here
Fusion Duplication is a recursion-style enabler: it banishes a Fusion or Polymerization Spell from either graveyard and then applies that Spell's effect, so its value is reusing an existing Fusion route rather than generating its own card advantage. It appears in all 400 sampled decks at about 1.17 copies each, across 39 archetypes, and 100% of its recorded boards, which supports a real, practical role. The high-power example boards (power index about 100) reflect the Fusion engines around the card, not the card itself, and the combo role counts are all zero, so the score does not credit those boards. Its effect interaction is minimal and its material value is nil, which keeps the score in the middle band.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 70 | Live in 400/400 decks, but it depends on a Fusion or Polymerization Spell being in a graveyard and cannot be searched (observed decks; inferred from text). |
| Combo & Conversion | 62 | Present in 10/10 recorded combos with an average power index of 83.2, but no starter, searched or payoff role is tagged, so the conversion credit is modest (observed; inferred). |
| Resource Economy | 50 | It banishes a graveyard Spell and re-uses its effect, a one-for-one reuse with no net card advantage stated in the text (verified text; inferred). |
| Effect & Interaction | 15 | No opponent interaction is described in the card text (verified). |
| Material Utility | 25 | It is a Trap Card, so it provides no monster body or material (verified from card type). |
| Resilience & Flexibility | 40 | Usable across both graveyards and appears in multiple archetypes, but as a Trap it is exposed to set-turn and activation-response risk; no counter evidence was supplied (verified text; inferred). |
| Deck-Building Efficiency | 75 | Averages 1.17 copies per deck with no garnet or lock restriction in the evidence, a cheap, redundancy-tolerant slot (observed; inferred). |
Calculation
Weight profile: 0.7 Starter/Combo enabler + 0.3 Recovery/Recursion. Intrinsic ≈ 55, Deck ≈ 64, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Present in every sampled deck, confirming a real and practical role
- Reuses an existing Fusion or Polymerization route from either graveyard
- Cheap to run: about one copy per deck, no garnet or lock restriction in evidence
- Broad archetype reach (39 distinct archetypes)
Weaknesses
- Conditional on a Fusion or Polymerization Spell being in a graveyard
- Trap timing and activation-response exposure
- No material value and no direct opponent interaction
- Combo evidence carries no role tags, so its exact conversion role is inferred
Counters / choke points
- Trap-activation negation (inferred; no counter evidence supplied)
Best use
Recursion of a Fusion or Polymerization Spell from either graveyard, enabling the Fusion route. Decks: Branded, Despia, Bystial/Byssted, Predaplant, Dogmatika, Relinquished, Phantom Beast (Chimera). Suggested copies: 1.
Evidence & gaps
- Verified: Card text: targets a Fusion or Polymerization Normal or Quick-Play Spell in either GY, banishes it, and applies its effect; Once per turn restriction; Card type: Trap Card
- Observed: Appears in 400/400 sampled decks, 1.17 copies average, 39 archetypes; Appears in 10/10 recorded combos, average power index 83.2; Top partners at 89.8% to 93.8% co-occurrence
- Inferred: Recovery/Recursion role from the banish-and-reuse effect; Conditional access depends on a Fusion or Polymerization Spell in a graveyard; Activation-response exposure as a Trap
- Data gaps: no guides supplied no banlist token, assumed unlimited (3 copies) combo role tags (starter, searched, material, payoff) all zero, so conversion role is inferred from text no counter or interaction evidence supplied
