Shaddoll Core — Power Evaluation

Final Score: 62 ± 6 · Confidence: Medium

  • Intrinsic: 60 · Deck: 64 · Meta: provisional
  • Primary role: Material body · Secondary: Recovery/Recursion, Combo enabler

Why it scores here

Shaddoll Core earns its score as an archetype-locked utility piece: it becomes a Level 9 DARK body usable as a Fusion substitute on a "Shaddoll" Fusion Monster and, when sent to the GY by a card effect, adds a "Shaddoll" Spell/Trap back from the GY — a real grindy recursion that shows up in 100% of the recorded Shaddoll combo boards and in all 400 sampled decks. Its 1450/1950 body and Trap-into-monster stats earn nothing here; the value comes from the substitute-material function and the GY recovery, which lift resource economy and material utility well above its near-zero direct interaction. Because it is an unsearchable Trap that must be drawn or set and is never the engine (starter role 0%), it cannot carry a line on its own, so it lands solidly mid-range rather than top-tier.

Axis scores

Axis Score Evidence
Accessibility 50 It runs in 400/400 sampled decks at ~1 copy, but it is an unsearchable Trap that must be drawn or set and shows 0% starter role and 0% searched-for role in the recorded combos (observed).
Combo & Conversion 55 It appears in 5/5 recorded combos carrying an average power index of 79.4, yet is never the starter (avg starter count 0.6), so it supports the line rather than driving it (observed).
Resource Economy 67 Its GY trigger adds a "Shaddoll" Spell/Trap from the GY to the hand, and the boards it appears in show net card advantage of +3 to +5 (observed).
Effect & Interaction 28 The card has no negation or removal text of its own; any disruption is indirect, coming only through recovering a "Shaddoll" Spell/Trap such as Schism (verified).
Material Utility 70 Summoned as a Level 9 DARK Spellcaster, it can substitute for 1 Fusion Material that lists an Attribute on a "Shaddoll" Fusion Monster, giving clean fusion-material value even when its own effects are irrelevant (verified).
Resilience & Flexibility 60 It functions both as a monster on the field and as a GY trigger whenever it is sent there by a card effect, giving it multi-zone utility that survives being destroyed by an effect (verified).
Deck-Building Efficiency 63 It costs an average of 1.03 copies per deck with 390 of 400 decks playing exactly one and no locks or costs attached, a cheap slot inside its archetype (observed).

Calculation

Weight profile: 0.7 Material body + 0.3 Recovery/Recursion. Intrinsic ≈ 60, Deck ≈ 64, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Turns into a Level 9 DARK Spellcaster body that can substitute for an Attribute-listing Fusion Material on a "Shaddoll" Fusion Monster
  • GY trigger recovers a "Shaddoll" Spell/Trap (e.g. Shaddoll Fusion, El Shaddoll Fusion, Schism), giving repeated value
  • Very low slot cost: 1.03 average copies and no locks or discard costs
  • Works from two zones (field monster and GY) and triggers even when destroyed by a card effect

Weaknesses

  • Unsearchable Trap that must be drawn or set, so it is slow and unreliable as an opening play
  • Provides no direct negation, removal, or disruption of its own
  • Heavily archetype-locked — near-worthless outside Shaddoll builds
  • Low body stats (1450/1950) make it a poor stand-alone monster

Counters / choke points

  • Called by the Grave / D.D. Crow to banish it before the GY recovery trigger resolves
  • Cosmic Cyclone or other Spell/Trap removal that banishes it instead of sending it to the GY
  • Macro Cosmos / Dimension Shifter-style graveyard hate that prevents it reaching the GY
  • Negating the Fusion summon it is substituting into removes its main material value

Best use

Fusion substitute material and GY recursion utility. Decks: Shaddoll, Shaddoll Invoked, Shaddoll Eldlich. Suggested copies: 1.

Evidence & gaps

  • Verified: Card text: can be Special Summoned as an Effect Monster (Spellcaster/DARK/Level 9/1450 ATK/1950 DEF) while remaining a Trap; Card text: when Summoned this way it can substitute for 1 Fusion Material that lists an Attribute on a "Shaddoll" Fusion Monster; Card text: if sent to the GY by a card effect, it can add a "Shaddoll" Spell/Trap from the GY to the hand (except "Shaddoll Core"); Card is a Continuous Trap, archetype Shaddoll, legal in TCG/OCG/MasterDuel/DuelLinks with no banlist restriction token
  • Observed: Runs in 400/400 sampled decks, average 1.03 copies (390 decks play exactly 1, max 3); Appears in 5/5 recorded combos (100% appearance) with average power index 79.4 and average starter count 0.6; 0% starter role, 0% searched-for role, 0% material role, 0% payoff role, 0% end-board appearances across recorded combos; Boards it appears in report net card advantage of +5, +3, and +4 in the worked examples; Top partners co-occur at 94-97% (El Shaddoll Construct, Shaddoll Fusion, Reeshaddoll Wendi)
  • Inferred: As an unsearchable Trap, its access depends on drawing it or sending it to the GY by effect rather than on a searcher route; Its practical function is support material plus GY recursion rather than a starter, consistent with the 0% starter role signal
  • Data gaps: no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from the 400-deck sample only combo data is very thin (5 combos) and all role tags (starter/searched/material/payoff/end-board/end-hand) are empty, so the exact role in the line is not directly confirmed
