Identity & game plan

• Win condition: Fusion-based OTK via Dragonne Kroah and Dragonecro Nethersoul Dragon; Graveyard recursion and board control with Skull Servant engine
• Turn 1 (going first): Set up Skull Servant core, search Dragonne Kroah or Wight components, establish board control and aim for turn 4-6 OTK
• Turn 2 (going second): Defend against early threats, use hand traps and disruption to survive until Dragonne Kroah can be searched and combo closed
• Recovery: Return key components from GY via Skull Servant recursion or Called by the Grave to rebuild the combo line
• After siding: Side into broad removal and floodgates; rely on Zombie World and hand traps to stabilize post-side

Why it scores here

The deck runs a clear Combo engine centered on Skull Servant and Dragonne Kroah with above-average ceiling (D3 70) but suffers from legality issues and inconsistency (D1 60, D2 45), leading to a low median floor (D4 50). Disruption capability is moderate (D7 65) while resource sustainability is weak (D6 40), and the format mismatch and brick risk keep the overall score in the 40–50 band.

Dimension scores

How the score was computed

Strategy profile: Balanced (Combo-primary). Structural ≈ 42, Going First ≈ 48, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: format_legality_penalty (-10); brick_rate_penalty (-8); extra_deck_coverage_bonus (5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex 82, median 61, board-per-starter 2.6
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High ceiling OTK potential with Dragonne Kroah + Dragonecro Nethersoul Dragon
• Strong Extra-Deck coverage and monster density
• Good removal and hand-trap disruption for the archetype
• Consistent 3-card Skull Servant core in 77.8% of builds

Weaknesses

• Illegal status due to Called by the Grave over limit
• Low consistency floor and brick risk (~13.7%)
• Poor resource economy and grind potential
• No side deck adaptability data and format mismatch
• High dependency on specific search targets

Critical choke points

• Search consistency for Dragonne Kroah / Wightlord
• Survivability vs targeted hand traps and backrow removal
• Lack of sustainable card advantage

Recommended changes

Evidence & confidence

• Verified: Card legality and banlist status from evidence.legality; Deck composition and Extra-Deck breakdown; Best line PowerIndex 82 from combos_evidence
• Observed: Archetype core presence (7/9 cards) in usage_statistics.core_cards; Hand trap and removal counts from composition.functional_counts
• Inferred: Consistency floor, brick rate, and open-probability from hypergeometric probabilities; Combo ceiling and median from best_line and board_per_starter; Format fit and meta parity due to absent tournament_context
• Provisional: Meta Power and matchup evaluations; Side deck adaptability
• Data gaps: No win-rate telemetry or matchup data in YGOVN No tournament link or per-pilot match record No post-side performance metrics Combo median/ceiling inferred rather than empirically recorded
