Myutant Expansion

Myutant Expansion — Power Evaluation

Final Score: 47 ± 6 · Confidence: Medium

• Intrinsic: 45 · Deck: 48 · Meta: provisional
• Primary role: Searcher/Tutor · Secondary: Combo enabler, Recovery/Recursion

Why it scores here

Myutant Expansion converts into exactly one Level 4 or lower Myutant — added to hand or Special Summoned — plus a one-time shield that keeps a Level 8 or higher Myutant from being destroyed by card effect. That is real, archetype-locked utility, but it is a Continuous Trap: it must be drawn and set before it does anything, so it is a slow follow-up rather than a turn-one starter, and the combo evidence records zero appearances to show a larger payoff. Its accessibility is limited by the trap timing and by the card not being shown to be searchable within its own archetype, so it lands in the mid-range. High ATK/DEF is irrelevant here — the card has none and none was counted; the score is driven by reliability, timing cost, and deck fit.

Axis scores

Calculation

Weight profile: 0.7 Searcher/Tutor + 0.3 Combo enabler. Intrinsic ≈ 45, Deck ≈ 48, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• Tutors any Level 4 or lower Myutant, choosing flexibly between adding it to hand or Special Summoning it
• Second clause is a free shield: banish this face-up trap to stop a Level 8 or higher Myutant from being destroyed by card effect
• No locks, no garnets, and redundancy is fine — played at ~1.94 copies on average with a clean 3-of option
• Near-universal in Myutant lists (Myutant ST-46 co-occurs at 100%, usage statistics show ~66.7% inclusion at 3 typical copies)
• Once resolved it can remain face-up, keeping the protection live across multiple turns

Weaknesses

• It is a Trap: it must be drawn and set a turn before it can resolve, so it is a slow follow-up rather than a reliable turn-one starter
• Effect is hard once-per-turn, so extra copies cannot be chained for a second search or Summon
• Card itself is not shown to be searchable inside the Myutant archetype — it must be naturally drawn
• Provides zero interaction with the opponent's plays; the protection only covers destruction by card effect
• Tutor is restricted to Level 4 or lower Myutant monsters, so it cannot fetch the Level 8+ bosses

Counters / choke points

• Spell/Trap removal before activation (Mystical Space Typhoon, Twin Twisters, Cosmic Cyclone)
• Negating the activation (Solemn Judgment and other Counter Traps) turns it into a wasted set
• Ash Blossom & Joyous Spring negates the Deck search/summon effect
• The protection only covers destruction by card effect — banish, negate, or return-to-hand removal ignores it
• Graveyard-hate floodgates (e.g. Macro Cosmos style effects) interact poorly with Myutant lines that rely on GY banishing

Best use

Archetype search / trap-based extender and boss protector. Decks: Myutant. Suggested copies: 3.

Evidence & gaps

• Verified: Card text: on activation, optionally take 1 Level 4 or lower Myutant from Deck, add to hand or Special Summon it; Card text: can banish this face-up card to prevent a Level 8 or higher Myutant from being destroyed by card effect; Card text: only 1 'Myutant Expansion' can be activated per turn; Card attributes: Continuous Trap, archetype Myutant, legal in TCG, OCG and Master Duel
• Observed: 225 decks run it, all in the main deck, at an average of 1.94 copies (distribution 1:83, 2:73, 3:69); 26 distinct archetypes appear alongside it, but the dominant homes are Myutant variants (~80% combined); Myutant ST-46 co-occurs in 100% of decks; M-05 97.3%; Emergency Teleport 91.6%; Ash Blossom & Joyous Spring 62.2%; Usage statistics: ~66.7% inclusion in Myutant archetype decks at 3 typical copies; combo data records 0 appearances, 0 as starter, 0 as material, 0 as payoff
• Inferred: Because it is a Trap, its search/Summon arrives a turn late and cannot function as a true turn-one starter; Trading the trap for one Myutant searched or Summoned is approximately card-neutral; Its protection clause contributes resilience for a Level 8+ Myutant rather than any opponent interaction; Special Summon mode supplies a Level 4 or lower Myutant body usable as material for Myutant Fusion plays
• Data gaps: no combos supplied — combo conversion is text-only inference no banlist token — assumed 3 copies (unlimited) no Myutant-specific guide coverage; the two guide mentions come from Thunder Dragon engine writeups no dated metagame sample, so meta power is provisional/null
