Kuriboh Deck #771899 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Control
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual and Extra Deck boss monsters (Black Chaos, Magician of Dark Chaos - Black Chaos, Black Luster Soldier, Chaos Angel, Galaxy-Eyes Photon Lord) that must survive a hand-trap-heavy opponent turn (Inferred from card text); Link and Fusion boards (A Bao A Qu, Accesscode Talker, Dark Paladin, Dark Cavalry) built from the Mulcharmy draw engine (Inferred)
• Turn 1 (going first): Open on Dark Magician / Magician's Rod / Dark Magical Curtain or Light and Darkness Ritual searches toward a ritual boss; hold Ash Blossom, Kuriboh - Multiply! and Solemn for the opponent's first Summon or activation (Inferred)
• Turn 2 (going second): Use hand traps (Ash, Kuriboh - Multiply!, Nibiru, Droll & Lock Bird, Solemn Judgment) to break the opponent's first board, then convert the 6-card hand into a ritual or Extra Deck summon (Inferred)
• Recovery: Mulcharmy Fuwalos / Purulia draw when the field is empty, plus Witch of the Black Forest and Dark Magical Circle for searches (Inferred)
• After siding: No Side Deck is run (Side Deck size 0), so there is no post-side plan; the deck cannot adapt between games (Verified)

Why it scores here

The deck is scored on its system, not by averaging its cards. Its interaction suite (three Solemn Warning, Ash Blossom, Dominus Impulse, Kuriboh - Multiply!, Droll & Lock Bird, Solemn Judgment, Harpie's Feather Duster) gives it real end-board and interruption resilience, which is why D5 and D7 are the strongest dimensions. Engine access is weak: P(at least one 3-copy starter in a 5-card opening hand) is about 0.23, and the Light and Darkness Ritual, Dark Magician and Mulcharmy engines pull in different directions (the Mulcharmy draw effects want an empty field), so the core is not reliably live on turns 1 to 2. No recorded boards exist, so the combo ceiling and median are text-only inferences and are rated low-confidence. The deck is Illegal as built (Ash Blossom and Dominus Impulse each run 3 copies against a Semi-Limited limit of 2), so the score is capped and labelled structural-only. Its popularity and the archetype label 'Kuriboh' (only 3 Kuriboh-named copies) did not earn points.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 49, Going First ≈ 46, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Banlist exposure (illegal copy counts) (-6); Engine conflicts (-4); No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (-12) = 36, then capped to 30 because the deck is Illegal (over copy limit on Ash Blossom and Dominus Impulse); Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.23 · 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

• Layered negation and hand-trap suite (Ash, Kuriboh - Multiply!, Solemn x3, Droll, Nibiru, Solemn Judgment)
• Several 3000+ ATK boss monsters that can close a game if they land

Weaknesses

• Illegal as built: Ash Blossom and Dominus Impulse exceed the Semi-Limited copy limit
• Weak starter density (P ~0.23 for a 3-copy starter in hand5)
• No Side Deck, so no post-side adaptation
• Engine split across Ritual, Dark Magician and Mulcharmy lines

Critical choke points

• The Light and Darkness Ritual line depends on 2 Light and Darkness Ritual Spells and Black Chaos being live
• Ash Blossom and Dominus Impulse counts must drop to 2 each before the list is legal

Recommended changes

Evidence & confidence

• Verified: Illegal: Ash Blossom and Dominus Impulse each run 3 copies, OCG Semi-Limited allows 2; Main 60, Extra 15, Side 0 are within OCG size rules; Droll & Lock Bird, Harpie's Feather Duster, S:P Little Knight and Solemn Judgment are Limited and run at 1 copy each (legal)
• Inferred: P(>=1 3-copy starter in hand5) ~0.23 hypergeometric estimate; Interaction suite strength from card text; Going-first and going-second splits from hand-trap and boss density
• Provisional: Meta Power (no dated meta sample); Matchup fit (no tournament data)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot records absent No win-rate telemetry (going-first, going-second, matchup, brick and starter rates) Meta Power is Provisional without a dated metagame sample
