Kuriboh Deck #763253 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Chaos Angel, Red Nova Dragon - Burning Soul, The Crimson King, Black Chaos, Black Luster Soldier) reached through Ritual and Synchro lines; theoretical only because the list is illegal; Mulcharmy draw-engine card advantage and Kuriboh-style hand-trap interaction stalling the opponent until a boss lands
• Turn 1 (going first): Open on a Droll & Lock Bird / Mulcharmy / Ash Blossom starter and search a Light and Darkness Ritual line; no verified turn-1 sequence exists in the evidence (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Maxx C, Infinite Impermanence and Solemn effects to answer the opponent's first summon or activation, then rebuild through the GY-recursion route (Inferred)
• Recovery: Mulcharmy and Skull Archfiend recursion plus Ritual Spell GY recovery (Light and Darkness Ritual) provide some rebuild paths; the density is unverified (Inferred)
• After siding: Not assessable: the list runs zero Side Deck cards, so there is no post-side plan in the evidence

Why it scores here

The deck is illegal in OCG because it runs one copy each of two Forbidden cards (Charmer Quartet in Bloom and Red-Eyes Dark Dragoon), so its structural score is recorded for reference only and the final score is capped at 20. Structurally it is a loosely connected toolbox: 29 distinct main-deck cards with only 4.3% exact Kuriboh-name purity, spread across Light and Darkness Ritual, Mulcharmy, Solemn, Dominus and Resonator pieces, so the engine coherence is weak. Its real strengths are interaction density (7 hand traps and roughly 10 negation texts) and a 15-card Extra Deck with several 3000+ ATK bosses, which give it some going-second and closing power. The evidence has no recorded boards and no side deck, so median and ceiling output, post-side adaptation and matchup fit stay unscored or provisional. Popularity did not earn points: the 92% inclusion of Droll and Lock Bird confirms the list is real, not that it is strong, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 44, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*44 + 0.20*38 - 12 = 31 pre-cap; Illegal cap (Forbidden cards run in OCG) sets Final = 20; structural-only, theoretical

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense interaction package: 7 hand traps plus Solemn and Dominus-style negations
• Large Extra Deck of boss monsters at 3000+ ATK (Chaos Angel, Red Nova Dragon, The Crimson King)
• Real searcher density (21 searcher-text cards), so the list usually finds something to do

Weaknesses

• Illegal in OCG: two Forbidden cards are run, so the list cannot be played as built
• Very low archetype purity (4.3%), with the Kuriboh core split across Ritual, Mulcharmy and Solemn engines
• No side deck, so there is no adaptation for best-of-3

Critical choke points

• Light and Darkness Ritual pieces are needed to reach the strongest bosses and conflict with the Kuriboh core
• Forbidden cards occupy two Extra Deck or Main Deck slots that the line depends on

Recommended changes

Evidence & confidence

• Verified: Two Forbidden cards are run (Charmer Quartet in Bloom and Red-Eyes Dark Dragoon); Main 55, Extra 15, Side 0; sizes are within the OCG range; Droll & Lock Bird is in 92% of archetype usage; Mulcharmy Fuwalos is in 65%
• Inferred: The Ritual and Synchro lines reach the boss monsters; The interaction density gives going-second strength; Consistency is limited by the split engines
• Provisional: Matchup and meta fit (no dated meta sample); Median output (no recorded boards)
• 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: going-first/second, matchup, brick and starter rates are Inferred or unknown Meta Power is provisional without a dated metagame sample no Side Deck supplied
