Kuriboh Deck #720582 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±8 · Confidence: Low)

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

Legality

Main 43 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos / Black Luster Soldier with end-board interaction; Fusion-based removal and recursion via Nadir Servant / Fallen of Albaz lines
• Turn 1 (going first): Establish a Ritual monster with protective effects or board disruption; limited negation coverage
• Turn 2 (going second): Hand traps (Ghost Ogre, Ash Blossom) into removal (Super Polymerization, The Fallen & The Virtuous) to clear blockers
• Recovery: Recursion via Skull Archfiend of Chaos, Mind Shuffle, and graveyard access; limited without Ecclesia core
• After siding: Unknown; no side deck supplied

Why it scores here

This deck is illegal in OCG due to Maxx C and Herald of the Arc Light both being Forbidden. Structurally, it attempts a Ritual-Fusion hybrid using Light and Darkness Ritual, Nadir Servant, and Fallen of Albaz, but suffers from weak consistency (only 3 core Kuriboh cards present despite running a Kuriboh archetype, relying instead on Light and Darkness Ritual as the primary engine). The deck's median combo output is modest—without scored boards to reference, text analysis shows ritual summons produce 1–2 interactive pieces but lack layering. Recovery is hampered by dependence on graveyard mills (Void Apocalypse, Nadir Servant cost), and the extra deck mixes incompatible strategies (Branded fusions, Synchro toolbox, Infernoid) without coherence. Going-second has decent hand traps but limited board-breaking density. The deck is fundamentally misaligned with its archetype label and lacks both the internal synergy and format positioning to be competitive.

Dimension scores

How the score was computed

Strategy profile: 0.70 Combo + 0.30 Midrange. Structural ≈ 39, Going First ≈ 38, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 32. Modifiers: Illegal deck penalty (-9); Weak archetype purity (-3); No side deck (-2). Final formula: Theoretical only; deck is Illegal in OCG. If legalized: 0.80*Structural(39) + 0.20*TournamentReliability(32) = 37, capped to 28 due to illegality penalty.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.38 · key two-card combo ≈ 0.15 · full-brick estimate ≈ 0.22 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Diverse removal options: Super Polymerization, The Fallen & The Virtuous, Ghost Ogre, and Ash provide multiple board-break angles
• Ritual boss monsters (Black Chaos, Black Luster Soldier) carry protection and 3000 ATK with battle immunity
• Hand trap density (7 copies) provides going-second interaction
• Graveyard recursion via Skull Archfiend, Mind Shuffle, and Ecclesia monsters enables multi-turn grinding

Weaknesses

• ILLEGAL: Maxx C and Herald of the Arc Light are Forbidden in OCG; deck cannot be played in sanctioned events
• Severe archetype misalignment: labeled Kuriboh but contains 0 Kuriboh-named cards; actual engine is Light and Darkness Ritual with Branded/Dogmatika splashes
• Weak consistency: Light and Darkness Ritual engine is inconsistent (P ≈ 0.32 for going-first opener); many single-copy tech cards dilute draw
• Single-line vulnerability: Ritual Summon commitment lacks redundant starters; disruption to ritual spell or tribute outlet breaks play
• Fragmented extra deck: 8 Fusions, 6 Synchros, 1 Link with minimal access pattern; most extra slots are flex and rarely reached
• Modest end-board: Ritual bosses provide 1–2 pieces of interaction; no dense layering or unbreakable protection
• Resource economy hampered by mill costs: Nadir Servant and Void Apocalypse send cards to GY as costs, reducing hand advantage
• No side deck for format adaptation
• Piloting complexity without payoff: multi-engine interactions (Ritual, Fusion, Synchro, Branded, Dogmatika) create decision overhead for fragile lines

Critical choke points

• Light and Darkness Ritual search/graveyard access is the primary engine; if disrupted (Ash Blossom on search, Maxx C on special summon) the deck stalls
• Nadir Servant is the Fallen of Albaz entry point; if sent to GY or negated, Branded/Dogmatika lines are cut off
• No alternative win condition: deck relies entirely on Ritual summon > interaction > grind; if ritual line fails, recovery is minimal
• Legality blocker: Maxx C and Herald of the Arc Light make the deck unplayable in OCG events immediately

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (Maxx C Forbidden, Herald of the Arc Light Forbidden in OCG); Card text: all 37 resolved cards read from evidence.json; Deck composition: 43 main, 15 extra, 0 side (verified against evidence); Archetype label: Kuriboh (verified from evidence deck.archetype field); Exact-name purity: 0 Kuriboh-named cards (verified from card list)
• Observed: Usage statistics show Light and Darkness Ritual at 100% inclusion in archetype (Mind Shuffle 100%, Super Polymerization 100%); this deck runs Mind Shuffle and Super Polymerization, aligning with Ritual meta
• Inferred: Consistency P(≥1 Ritual starter in hand5) ≈ 0.38 based on hypergeometric draw model from 7 core starters in 43-card main; Brick estimate ≈ 0.22 due to high spell density (15 Spells) and seven single-copy tech cards; Median combo output: 1–2 pieces of interaction per line, inferred from end-board card text (Ritual bosses + removal); Going-first plan resilience (D5 ≈ 35): single ritual-line commitment with limited redundancy; Extra-deck efficiency modest: 8 Fusions (mostly flex), 6 Synchros (split across Chaos, Branded, toolbox), 1 Link; access pattern unclear; Pilotability complexity high due to multi-engine interactions (Ritual, Fusion, Synchro, Branded, Dogmatika) for modest payoff
• Provisional: Meta Power: no dated metagame sample supplied; Kuriboh archetype popularity/meta-share unavailable; cannot assess format fit; Tournament reliability: no win-rate data in YGOVN; brick/mulligan frequency unknown; best-of-3 side-deck adaptation impossible
• Data gaps: Deck is Illegal in OCG (Maxx C and Herald of the Arc Light Forbidden); evaluation is theoretical/structural only No scored combos provided; combo floor/median/ceiling inferred from text only No tournament context; archetype meta-share and per-pilot match record absent No side deck supplied; post-side adaptation and resilience untestable No win-rate telemetry or game-level brick/starter rates available in YGOVN Meta Power is Provisional and cannot be computed without a dated metagame sample Archetype identity mismatch makes usage statistics (Light and Darkness Ritual, not Kuriboh core) difficult to reconcile
