Activate this card by targeting 1 Level 4 or higher monster you control; Special Summon this card as an Effect Monster (Rock-Type/EARTH/Level 4/ATK 1000/DEF 1000), then equip that face-up monster to this card. (This card is also still a Trap Card.) If Summoned this way, this card gains ATK and DEF equal to the ATK of the monster equipped to it by this effect, also if it attacks, change it to Defense Position at the end of the Damage Step.
Metamorphortress — Power Evaluation
Final Score: 46 ± 5 · Confidence: Medium
- Intrinsic: 47 · Deck: 47 · Meta: provisional
- Primary role: Utility · Secondary: Material body, Board control
Why it scores here
Metamorphortress is a defensive utility piece that converts an existing board presence into a stat-boosted, immobilized form. While it provides a generic Level 4 Rock body and modest board control via Defense Position locks, it generates no card advantage, requires setup, and lacks combo multipliers or recovery. Its 1-copy inclusion across eight archetypes confirms modest splashability, but the absence of combo evidence and guides limits confidence in deep impact.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 47 | Requires pre-existing Level 4+ monster on-field; available as a Trap that can be set, but setup-dependent (inferred) |
| Combo & Conversion | 27 | Converts one equipped monster into a defensive, stat-boosted body; no combo examples supplied and no multiplication of resources (inferred) |
| Resource Economy | 42 | No card draw or advantage generated; equips one monster (removing it from active play) in exchange for a new Effect Monster form (verified) |
| Effect & Interaction | 17 | Forces Defense Position after attacking, providing soft board control; lacks negation, removal, or hard disruption (verified) |
| Material Utility | 60 | Becomes a generic Level 4 Rock-Type EARTH Effect Monster suitable for Fusion/Synchro/Xyz material requirements (verified) |
| Resilience & Flexibility | 45 | Protected as a Trap Card while face-down; Effect Monster form is vulnerable to spell/trap removal; no recovery or recursive effects (verified) |
| Deck-Building Efficiency | 52 | Runs 1 copy per deck across 8 distinct archetypes; requires pre-existing Level 4+ monsters, but broadly splashable (observed) |
Calculation
Weight profile: Utility (default, no single primary role). Intrinsic ≈ 47, Deck ≈ 47, Meta = provisional. Modifiers: Unusual dual Trap/Monster mechanic (-1). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Becomes a live Effect Monster from Trap activation via hand
- Gains ATK equal to equipped monster (scales with board presence)
- Generic Level 4 Rock-Type body for material requirements
- Splashable across multiple archetypes (8 distinct homes observed)
- Protected when set as a Trap Card
Weaknesses
- Requires pre-existing Level 4+ monster to activate (setup cost)
- Immobilizes the equipped monster in defensive form
- Forces this card to Defense Position after attacking (removes aggressive play)
- Generates no card advantage, search, or resource multiplication
- Vulnerable to spell/trap removal once summoned as Effect Monster
- No recovery or recursive effects
- Limited 1-copy inclusion suggests lower priority or lack of tutoring
Counters / choke points
- Spell/trap removal (Harpie's Feather Duster, Mystical Space Typhoon)
- Monster removal or destruction (breaks the equip relationship)
- Effect negation (negates activation or stat gain)
- Archetype-specific floodgates (Shadow-Imprisoning Mirror on Rock-Types)
- Hand traps that block Level 4+ monster summons
Best use
Defensive form-shifting and board utility. Decks: Fossil, Greed, Hole, Adamancipator. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: activates by targeting Level 4+ monster you control, becomes Level 4 Rock-Type EARTH Effect Monster with base 1000 ATK/DEF, gains ATK equal to equipped monster's ATK, forces Defense Position after attacking; Continuous Trap type with dual Trap/Monster nature; Deck usage: 15 decks, 1 copy per deck, across 8 archetypes; Formats: TCG, OCG, MasterDuel, DuelLinks; No archetype affiliation
- Observed: 8 distinct archetypes run this card (Fossil 40%, Greed 13.3%, Hole 13.3%, Adamancipator 13.3%, others 20%); Top partners include Triple Tactics Talent (53.3%), Miracle Rupture (46.7%), Harpie's Feather Duster (40%); 60% of decks focus on gameplay type 4 (control/tempo), 26.7% on type 7, 13.3% on type 6; Fossil archetype shows strong co-deck synergy (6 co-decks of 15)
- Inferred: Requires Level 4+ monster setup to activate (board state dependency); Material utility for Level 4/Rock/EARTH requirements; Soft board control via Defense Position lock (disruption without stopping opponent actions); Splashability across 8 archetypes suggests moderate generic utility; 1-copy inclusion suggests focused role rather than staple status
- Data gaps: No combos supplied — combo conversion impact and board-building efficiency are text-only inferences No guides supplied — no human expert context on optimal use or role clarification No banlist token — assumed unlimited, but 1-copy usage suggests otherwise No usage statistics (StatisticsCard) — archetype inclusion % inferred from 15-deck sample only No Fossil archetype synergy clarification — unclear if Fossil is the primary home or secondary use No ruling edge cases for the dual Trap/Monster mechanic
