Kuriboh Deck #725482 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Ritual Summoning, Synchro Spam
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ritual and Synchro beatdown via Level 8 monsters; Synchro spam into multiple interaction layers
• Turn 1 (going first): Ritual Summon Black Chaos or Black Luster Soldier; support with Synchro Monsters for interruption
• Turn 2 (going second): Synchro-based board breaking via Stardust Dragon and Chaos Archfiend
• Recovery: Graveyard recursion through Skull Archfiend of Chaos and Mind Shuffle; resummoning via Ritual effects
• After siding: No side deck present; no post-side adaptation possible

Why it scores here

This deck is illegal in OCG (Maxx "C" Forbidden), making it unplayable in its intended format. Beyond that fundamental issue, the list suffers from severe structural problems: it runs only 8% of the standard Kuriboh/Light-and-Darkness Ritual core, mixing conflicting engines (Branded, Ritual, Synchro, generic beatsticks) with no clear synergy. The opening consistency is weak (only 4 core starters, P(≥1 live) ≈ 43%), brick risk is high, and the combo floor is low—most draws produce disjointed plays rather than coherent boards. While the Extra Deck offers reasonable Synchro interaction, the main deck is bloated with underutilized cards, and the absence of a side deck means zero post-game adaptation. The deck is fundamentally broken in construction and illegal as written.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 32, Going First ≈ 38, Going Second ≈ 28, Meta = provisional, Tournament Reliability ≈ 22. Modifiers: Illegality (Maxx "C" Forbidden) (-15); No side deck (-5); Conflicting engines / low coherence (-8). Final formula: Illegal deck — structural capped at 32; no meta sample available. Final = 0.80·32 + 0.20·22 = 25.6 + 4.4 = 28 (rounded), with illegality penalty holding score low.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.43 · key two-card combo ≈ 0.18 · full-brick estimate ≈ 0.35 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Extra Deck is well-constructed with 10 Synchro Monsters offering multiple interaction points (negation, removal, recursion)
• Ritual Summoning engine (Black Chaos, Black Luster Soldier) provides robust Level 8 bodies with protective text
• Moderate hand-trap density (Ash Blossom, Droll & Lock Bird, Griffoh) for going-second disruption
• Graveyard-centric recursion via Skull Archfiend and Mind Shuffle enables some resource recovery

Weaknesses

• Deck is Illegal (Maxx "C" Forbidden in OCG); cannot be played in the intended format
• Only 8% archetype-core inclusion; massive deviation from standard Kuriboh/Light-and-Darkness Ritual decks signals either experimental build or fundamental misconstruction
• High brick rate (~35-40%); conflicting engines (Ritual tributes vs Synchro materials vs Normal Summon constraints) leave many hands unplayable
• Opening consistency very poor: P(≥1 live starter) ≈ 43%; only 4 dedicated starters + 2 ritual spells create fragile bootstrap
• No clear synergy between Ritual Summoning, Synchro, Branded, and generic components; deck identity incoherent
• Single choke point: if Ritual Summon is interrupted and no backup Synchro line is active, turn often ends with no board
• Lacks dedicated going-second board-breaking tools; Synchro removal slow and conditional
• No side deck (0/15); impossible to adapt in best-of-3 play
• Low pilotability: multi-engine sequencing is error-prone; decision trees steep

Critical choke points

• Interrupted Ritual Summon with no active Synchro summon leaves field empty; single-choke-point recovery
• Limited hand-trap density (only 3 relevant copies: Ash ×2, Droll ×1); opposing deck can play through
• Maxx "C" running Forbidden renders entire deck Illegal before play begins
• No side deck means zero metagame flexibility; cannot pivot strategy post-Game 1

Evidence & confidence

• Verified: Legality status: Illegal (Maxx "C" Forbidden in OCG); Main/Extra/Side deck sizes: 40/15/0 (legal size, illegal card present); Archetype purity: 0% exact Kuriboh, 8% core Light-and-Darkness Ritual (from usage_statistics); Card text snippets: all card excerpts resolved
• Observed: 4 dedicated starters (Fydraulis, Griffoh, Black Chaos, Skull Archfiend); High duplicate Level 8 density across 8 cards; Synchro Extra Deck well-distributed: 10 Synchro, 3 Fusion, 1 XYZ, 1 Link
• Inferred: P(≥1 core ritual/synchro starter in opening 5) ≈ 43% from hypergeometric; archetype-core availability group P = 0.4271 (Inferred); Brick rate estimate ~35-40% from conflicting engine densities and duplicate roles (Inferred); Combo ceiling ≈ 2-3 interruption layers based on Synchro interaction text; no parsed boards (Inferred); Going-first power ≈ 38: Ritual Summon + Synchro backup enables moderate protection; going-second ≈ 28: removal conditional and slow (Inferred); Tournament Reliability ≈ 22: high brick rate, single choke point, illegality, no side deck (Inferred); Pilotability low: multi-engine sequencing error-prone; decision trees steep for ritual/synchro balancing (Inferred)
• Provisional: Meta Power: null (no dated metagame sample supplied; archetype meta-share unknown; deck is Illegal so format alignment moot); Matchup coverage: Provisional without dated meta; illegal deck status voids all tournament context
• Data gaps: No parsed combo boards; all ceiling/floor/median power is text-only Inferred No tournament context; archetype meta-share absent (available: false in evidence) No win-rate telemetry; going-first/second, matchup, brick/starter rates are Inferred only No dated metagame sample; Meta Power remains Provisional/null Guides evidence empty (0 guides supplied) No side deck (0/15); post-side plans impossible to evaluate
