Gunkan Deck #771791 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Gunkan Extra Deck boss monsters (Uni-class Super-Dreadnought, Ikura-class Dreadnought) built from the Shari / Shari Red / Uni engine, backed by Kaiju and Extra Deck finishers.; Going-second disruption into Kaiju Special Summons (Gameciel, Dogoran) and Lava Golem pressure.
• Turn 1 (going first): Open a Shari or Uni starter with Small World / Ikura search, then Xyz or Synchro into a Gunkan boss. Interaction is held back for the opponent's turn because the list is hand-trap heavy.
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Infinite Impermanence, Droll & Lock Bird) and Solemn / Lightning Storm to break the opponent's board, then rebuild with Gunkan Extra Deck summons.
• Recovery: Recursion through Gunkan Shari Red and Uni searches, and Ghost Belle GY recovery. Recovery depends on a Gunkan monster surviving the interruption.
• After siding: Not evaluable: the deck has an empty Side Deck, so there is no post-side plan in the evidence.

Why it scores here

This list is Illegal as submitted: it runs 2 copies of Kashtira Fenrir, which is Forbidden in OCG, so the score is capped at a theoretical, structural-only value and is not a normal final score. Structurally the system opens a Gunkan starter about 25% of the time in a 5-card hand (hypergeometric, Inferred), and the 15 archetype-core copies give about 81% at least one in hand (Inferred). Its strength is interaction density: 10 hand traps, 18 negation texts and 20 removal texts, which earn the interaction and resilience dimensions. Its Extra Deck finishers are strong, but only 13 of 55 Main Deck copies are exact-name Gunkan (18.6% purity) and the Side Deck is empty, so consistency and post-side scores stay low. No combo boards, tournament link or metagame data exist, so popularity and archetype usage earned no points. The score comes from the system's consistency, interaction and closing structure, not from averaging the card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun interaction emphasis noted in text but not blended into weights. Structural ≈ 52, Going First ≈ 40, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: off_archetype_density (-4); no Side Deck (-2). Final formula: Structural 52 and TournamentReliability 45 give 0.80*52 + 0.20*45 = 50.6 (theoretical); Illegal cap applied, final = 20 (Meta provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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: 10 hand traps plus negation and removal text across 18 and 20 cards
• Strong Extra Deck closers with 2900-3000 ATK bosses across Xyz and Synchro
• Archetype-core group reaches about 81% at least one copy in a 5-card hand

Weaknesses

• Illegal as submitted: 2 copies of Forbidden Kashtira Fenrir
• Low exact-name Gunkan purity (18.6%) with many off-archetype staples
• Empty Side Deck, so no post-side plan
• No combo boards, so ceiling and median are unmeasured

Critical choke points

• A Gunkan Shari or Uni starter in opening hand (about 25% per 3-copy card, Inferred)
• Dependence on Gunkan Extra Deck bosses that require the engine to survive interruption

Recommended changes

Evidence & confidence

• Verified: Illegal status: Kashtira Fenrir x2 is Forbidden in OCG (0 legal copies); Main 55 and Extra 15 are within the OCG size rules; Side 0; Archetype purity 13 exact-name of 70 Main/Extra copies (18.6%); Probability figures recomputed from the resolved list
• Inferred: Engine accessibility and brick estimates from hypergeometric draws; Interaction density from card-text hints; Going-second hand-trap coverage (0.719 at least one in 6 cards)
• Provisional: Meta Power and matchup fit (no dated metagame sample)
• Data gaps: Illegal list: Kashtira Fenrir x2 must be removed before a normal score is possible No combo boards supplied: combo floor, median and ceiling are text-only No tournament link: archetype meta-share and per-pilot record absent Usage stats say Gunkan Suship Ikura-class Dreadnought (75215744) is missing from the deck, but the card list shows 1 copy in the Extra Deck; resolve before recommending No win-rate telemetry for OCG Gunkan Side Deck empty, so no post-side evidence
