Scareclaw Deck #771483 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 50 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Kashtira Ogre / Kashtira Unicorn / Scareclaw Kashtira beatdown, backed by Kashtira Shangri-Ira Xyz pressure (Inferred from card text); Red-Eyes Flare Metal Dragon, Number 11: Big Eye (control steal), Dark Armed (removal-Xyz) as Extra Deck pressure (Inferred)
• Turn 1 (going first): Open a Kashtira or Scareclaw starter, search or Special Summon a second Kashtira body, and keep Ash Blossom / Ghost Belle / Ghost Ogre up as hand traps (Inferred)
• Turn 2 (going second): Use 6-card hands with multiple hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Infinite Impermanence, Droll & Lock Bird) to answer the opponent's first board, then rebuild through Kashtira Birth and Shangri-Ira (Inferred)
• Recovery: Kashtira Birth and Mulcharmy/Kashtira searchers return banished or GY Kashtira monsters to the field (Inferred from text)
• After siding: Not applicable: no Side Deck is registered, so the deck cannot side (D12 scored at floor)

Why it scores here

The deck is scored on its structure only, because the list is illegal in OCG: it runs 3 copies of Kashtira Fenrir (Forbidden), 3 Kashtira Unicorn and 3 Tearlaments Kashtira (Limited, 1 legal copy each), and 3 Ash Blossom (Semi-Limited, 2 legal copies). Opening odds are modest: P(at least one archetype-core card in a 5-card opening hand) is about 0.55, so the Kashtira engine is live on the first turn only about half the time (Inferred). Hand-trap density is the deck's strongest feature, with 16 hand traps and about 0.92 odds of at least one going second in a 6-card hand (Inferred), which lifts interaction and going-second scores. The rest of the system is weak: there are no recorded boards, no combo floor or median, no Side Deck, and the off-archetype spread (Mulcharmy, Broken World, Red-Eyes, Mecha Phantom Beast) means the engine is not coherent. Popularity and archetype usage did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: 100% Midrange; Toolbox traits noted but not blended. Structural ≈ 49, Going First ≈ 42, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); illegal-deck cap applied: 35 pre-cap to 20

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.55 · key two-card combo ≈ — · full-brick estimate ≈ 0.45 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 16 hand traps and 3 floodgate-style cards give strong going-second interaction (Inferred)
• Kashtira searchers and recursion give some continuity (Inferred from text)
• Extra Deck has 15 cards with flexible Xyz options (Verified count)

Weaknesses

• Illegal in OCG: Kashtira Fenrir Forbidden and three Limited/Semi-Limited cards run over the copy limit (Verified)
• Low core-engine access: about 0.55 chance of a live starter in the opening 5 (Inferred)
• No Side Deck, so no post-side plan (Verified)
• Off-archetype spread dilutes the engine (Verified count)

Critical choke points

• Kashtira core cards (Unicorn, Tearlaments, Fenrir) are over the legal copy limit, so the deck cannot be built as listed
• Single-starter openings are common; about 45% of opening hands have no core starter (Inferred)

Recommended changes

Evidence & confidence

• Verified: Illegal: 4 cards over the copy limit under the OCG ban list (Verified); No Side Deck registered (Verified); Extra Deck is 15 cards: 12 Xyz, 3 Link (Verified)
• Inferred: Opening-hand odds for core starters (Inferred, hypergeometric); Going-second hand-trap coverage of about 0.92 (Inferred, hypergeometric); Interaction density from text scaffold (Inferred, semantic)
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry for OCG; brick, starter and matchup rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck registered; post-side adaptability cannot be assessed deck is Illegal; score is capped and treated as theoretical/structural-only
