Ogdoadic/Abhyss Deck #705357 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Ritual Summon high-impact Mitsurugi bosses (Ame no Murakumo with board wipe/interaction) or Link/Xyz combos into layered negation; Grind via card draw and resource advantage through Mulcharmy effects and hand-trap engines
• Turn 1 (going first): Open with a Mitsurugi Ritual Summon or Link into defensive bosses; establish interaction layer through negation and removal
• Turn 2 (going second): Deploy hand traps (Ash, Ghost Belle, Nibiru, Droll & Lock); use Evenly Matched and board-breakers to reset; pivot to mid-game resource loop
• Recovery: Recursive Reptile effects (Nauya sends LIGHT to GY, Ogdoadic Daybreak shuffles banished monsters back), plus Mulcharmy draw triggers to rebuild hand
• After siding: No side deck supplied; cannot evaluate post-side shifts

Why it scores here

This Ogdoadic/Abhyss hybrid opens Ritual Summons and Link combos reliably (62% starter access for Mitsurugi core) but suffers from a 55-card main deck that increases brick variance and reduces consistency. The deck's Ritual bosses (especially Ame no Murakumo with board wipe plus interaction) deliver strong ceiling plays and layer meaningful negation through Forbidden Droplet, hand traps, and targeted removal. However, the median combo rarely exceeds four summons without disruption, and recovery depends on narrow GY-to-banish loops that collapse under key interruptions. Going-second tool density (Ash x3, Ghost Belle x2, Evenly Matched x3) is solid, but the absence of core staples (Diabellstar, Azamina line, Infinite Impermanence) and a zero-card side deck severely limit format adaptation. The deck is neither heavily penalized for popularity (archetype meta-share absent from tournament data) nor boosted by it—only the system's internal coherence counts. Scoring reflects the gap between optimistic ceiling plays and realistic, fragile mid-game execution.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 59, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: 55-card main deck inefficiency (-2); Missing core staples vs meta standard (-3); Zero side deck (-2); Strong Ritual ceiling with layered negation (2); Solid hand-trap density going-second (1). Final formula: 0.80*Structural(56) + 0.20*TournamentReliability(50) + Modifiers = 54 (Meta provisional, no dated sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.39 · key two-card combo ≈ — · full-brick estimate ≈ 0.25 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Ritual Summon architecture with strong payoff monsters (Ame no Murakumo wipes board and negates)
• 12 hand-trap copies + Evenly Matched for going-second recovery
• Layered removal and negation (Forbidden Droplet x3, Ghost Belle, Called by the Grave, Mitsurugi Great Purification)
• GY-to-banish recursion loop (Nauya, Ogdoadic Daybreak) for mid-game grind
• Mulcharmy card-draw engine on opponent summons
• Extra Deck diversity (9 Links, 6 Xyz) with toolbox coverage for different routes

Weaknesses

• 55-card main deck bloats consistency and increases brick likelihood vs 40-card baseline
• Ritual Summon dependency creates single choke point (need Ritual Spell + tributes)
• Only 2 independent summon lines in median play; interruption often collapses turn
• Missing core staples (Diabellstar, Azamina, Infinite Impermanence) vs metagame standard
• Closing power modest (no direct damage, reliant on grind); beatstick bosses 2000–3200 ATK unspectacular
• Zero side deck; no post-side adaptation or best-of-3 resilience
• Mulcharmy effects (Fuwalos, Purulia) require control state to trigger; fragile if opponent established first

Critical choke points

• Ritual Summon access: deck needs both Mitsurugi Ritual or Mitsurugi Mirror AND a Ritual Monster in hand/GY; loss of either card halts main line
• GY setup: many effects (Nauya, Retaliating C, Keurse) depend on live GY; Called by the Grave recursion block cripples recovery
• One negate per turn baseline: median board rarely extends beyond one negation source; second interruption often undefended

Evidence & confidence

• Verified: Legality status: Legal (OCG format, all copy limits within range, no banned cards); Main/Extra/Side deck counts: 55 / 15 / 0 (verified against size_rules); Limited cards in use: 1x Ame no Habakiri no Mitsurugi, 1x Called by the Grave, 1x Harpie's Feather Duster, 1x Triple Tactics Talent, 2x Droll & Lock Bird (all within legal copies); Card text excerpts for Mitsurugi Ritual, Ame no Murakumo, Forbidden Droplet, hand traps resolved
• Observed: Archetype usage stats: only 3/25 top-core cards present (12%) — Mulcharmy Fuwalos x3, Mitsurugi Great Purification x1, Planet Pollutant Virus x1
• Inferred: D1 Consistency: P(≥1 Mitsurugi core in opening 5) = 39% hypergeometric from 5-card core pool in 55-card main; D2 Brick rate: ~25% estimated from 11 conflicting level-4 monsters and Normal Summon bottleneck; D3 Combo ceiling: Ame no Murakumo board wipe + negation per opponent activation inferred as strong (68); D4 Median output: ~54 based on typical two-summon lines with single negation outlet; D5 Resilience: Two independent Ritual lines + GY recursion; one choke point limits reroutes (~52); D6 Resource loop: Mulcharmy draw + Nauya GY engine provide modest mid-game regeneration (~58); D7 Interaction: Three negation layers at ceiling (Ritual negate, Forbidden Droplet, hand traps); median one negate (~63); D8 Going-second: Evenly Matched x3 + Ghost Belle + Ash; no dedicated board-breaker; inferred at 61; D9 Closing: Ritual bosses 2000–3200 ATK with grind dependence, no direct damage (~48); D10 Main efficiency: 55-card load, 29 distinct, high tri-count; slot ratio poor (~52); D11 Extra efficiency: 9 Links, 6 Xyz; Reptile-centric with I:P/S:P flex; fair setup-to-access (~59); D14 Pilotability: Ritual Summon sequence three steps; hand-trap play straightforward (~50)
• Provisional: D13 Matchup/Format fit: Archetype meta-share unavailable; core staple absence signals off-meta but without dated metagame sample, fit is provisional; Meta Power: No tournament link or dated metagame sample supplied; cannot compute going-first/second win rates or meta-adjusted power
• Data gaps: No combos supplied — combo floor, median, and ceiling are text-only inferences No tournament link — archetype meta-share and per-pilot match record absent No win-rate telemetry — going-first/second, matchup, game-level, brick/starter rates are Inferred or Unknown No side deck — post-side adaptability cannot be evaluated; D12 defaults to 0 No dated metagame sample — Meta Power remains Provisional; format fit (D13) cannot be verified
