- Intrinsic: 56 · Deck: 61 · Meta: provisional
- Primary role: Extender · Secondary: Searcher/Tutor, Combo enabler
Why it scores here
Metamorphosis is a reliable Fusion enabler that converts on-field monsters into powerful Extra Deck summons, confirmed by its presence in 400 recent decks across 123 archetypes including Fairy Tail, Magistus, and Dark Magician strategies. The card's strength lies in resource efficiency—tributing a weaker body for a better Fusion—and splashability into any deck running Fusion monsters. However, it lacks direct disruption or card advantage generation, is vulnerable to hand traps that negate spell effects, and the absence of recorded combo boards limits validation of its true conversion value.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 70 | Played in 400 recent decks across 123 archetypes at 1.54 avg copies, confirming reliable access in Fusion strategies; requires deck setup (monster to tribute) and Fusion targets (observed). |
| Combo & Conversion | 65 | No combo boards recorded; inferred from text to convert 1 tribute into 1 Fusion summon; deck co-inclusion with Super Polymerization (56.5%) and Mulcharmy cards (54.2%) suggests solid extender value in known lines (observed). |
| Resource Economy | 60 | Tribute cost is offset by Fusion summon; exchanging low-value bodies for high-value Fusions improves board efficiency, but card itself generates no card advantage or refuel (inferred). |
| Effect & Interaction | 5 | Zero disruption, negation, or removal in card text; all interaction value comes from the Fusion summoned, not from this card itself (verified). |
| Material Utility | 0 | Spell Card type cannot serve as Synchro, Xyz, Link, or Fusion material; zero material utility even when effect is negated (verified). |
| Resilience & Flexibility | 45 | Resolves once and leaves control to the Fusion; vulnerable to hand traps including Ash Blossom (71.8% co-inclusion) and Droll (69%) before resolution; post-resolution protection depends on Fusion's resilience (observed). |
| Deck-Building Efficiency | 75 | Requires Fusion Extra Deck and tribute targets; minimal garnet risk in Fusion-focused decks; run at 1–3 copies with player preference for 2–3, indicating near-free inclusion in natural homes (observed). |

Evidence & gaps
- Verified: Card text: Tribute 1 monster, Special Summon 1 Fusion with same Level from Extra Deck; Card type: Normal Spell (no once-per-turn clause stated); Legal in: TCG, OCG, MasterDuel; Assumed legal copies: 3 (no banlist token provided); Spell type cannot be used as material for Synchro, Xyz, Link, or Fusion summons
- Observed: Included in 400 recent decks (June–Sept 2026), 100% main deck; Played across 123 distinct archetypes; highest in Fairy Tail (8.5%), Magistus (5%), Mitsurugi (3.5%); Avg 1.54 copies per deck; 56.5% single, 33.5% double, 10% triple; Co-run with Super Polymerization (56.5%) and Mulcharmy cards (54.2%); 100% inclusion in 7+ archetypes including Gravekeeper's, Monarch, Ninja, Gaia
- Inferred: Card enables Fusion summons outside normal summoning routes, extending combo lines; Tributing a low-value body for a high-value Fusion improves board efficiency; No card advantage generation beyond the inherent effect of the Fusion summoned; Accessibility depends on deck having Fusion targets and available tribute material; Single-use effect leaves ongoing board control to the summoned Fusion
- Data gaps: No combos supplied — combo conversion is text-only inference; cannot validate boardstate power from recorded examples No guides supplied — cannot confirm community consensus on optimal role or use cases No banlist token — assumed 3 copies unlimited (no impact on current legal formats)
