Gunkan Deck #764589 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange
• Format: ocg

Legality

Main 40 / Extra 13 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Gunkan Xyz Monsters (Shirauo-class Carrier, Ikura-class Dreadnought, Uni-class Super-Dreadnought) built from Gunkan Level 4/5 starters, closing with 2200-2900 ATK bodies and direct-attack or double-attack text.; Fusion Summons via Super Polymerization (Garura, Starving Venom, Mudragon, Predaplant Dragostapelia) and AA-ZEUS as a late-game Xyz finisher.
• Turn 1 (going first): Open Gunkan Suship Shari plus a Gunkan starter (Shari Red, Uni, Ikura, Shirauo), search with Painful Decision or Catch-of-the-Day, and Xyz Summon a Gunkan Xyz. Theoretical only: the list is illegal as built.
• Turn 2 (going second): Use Nibiru, Change of Heart and Raigeki to clear or steal the opponent's board, then rebuild Gunkan Xyz Monsters from the hand. Support is thin: 3 hand traps and no floodgates.
• Recovery: Recover through Gunkan searchers (Ikura excavate, Shirauo, Catch-of-the-Day) and Shirauo-class Carrier's card advantage. The number of distinct recovery lines is not measured, since no combos were supplied.
• After siding: None. The deck runs 0 side cards, so it has no post-side plan.

Why it scores here

The deck is Illegal as submitted: it runs 3 copies of Super Polymerization against an OCG Semi-Limited limit of 2, so this is a theoretical, structural-only read and the final score is capped low. Structurally, the Gunkan starter density (3 Shari, 3 Shari Red, 2 each of Uni, Ikura, Shirauo and Catch-of-the-Day) gives a moderate chance of a live starter, and the three Gunkan Xyz Monsters provide a strong closing body. Hypergeometric odds for a single 3-copy starter in the opening 5 are about 0.34, so the engine is real but not reliable. No recorded combos, tournament context or guides were supplied, so the median and floor are inferred rather than measured. The score comes from the engine structure, a limited hand-trap and removal suite, and a 13-card Extra Deck on the system; it does not come from averaging card scores or from Gunkan being a popular archetype.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12); dependence on one Extra-Deck family (0); no side plan (0). Final formula: No-meta formula: 0.80*Structural(52) + 0.20*TournamentReliability(40) + modifiers(-12) = 37.6, then the Illegal cap applies: final = min(37.6, 25) = 25. Structural-only, theoretical read.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Gunkan starter density with 3-copy Shari and 3-copy Shari Red gives a real engine entry.
• Three Gunkan Xyz Monsters at 2200 to 2900 ATK with direct-attack and double-attack text.
• Searchers (Painful Decision, Catch-of-the-Day, Ikura) and Carrier's draw/search support grind.

Weaknesses

• Illegal as built: 3 Super Polymerization against an OCG limit of 2.
• No side deck, so there is no post-side adaptation.
• Only 41.5% exact-name archetype purity: 31 off-archetype copies such as Lava Golem, Nibiru, Raigeki and Super Polymerization.

Critical choke points

• Super Polymerization is the only Fusion enabler, and it is over the copy limit, so the 4 Fusion monsters cannot be reached legally.
• A 3-copy starter gives about 34% odds of at least one in the opening 5, so the engine is not reliable on its own.

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 13 / Side 0 counts are within the OCG size rules.; Super Polymerization runs 3 copies against an OCG Semi-Limited limit of 2, so the deck is Illegal.; Archetype purity is 41.5% exact-name; 9 Xyz monsters and 4 Fusion monsters are present.; No combos, tournament link, guides or win-rate telemetry are supplied.
• Inferred: A 3-copy starter has about 34% odds of at least one in the opening 5 (hypergeometric).; Gunkan Xyz bodies give a strong closing ceiling if the starter lands.; Interaction density is moderate (Raigeki, Change of Heart, 3 negation-text effects).
• Provisional: Meta power and format fit: no dated metagame sample supplied.
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot record are absent. No win-rate telemetry exists for going-first/second, matchup, brick or starter rates. Meta Power is provisional without a dated metagame sample. Side deck is empty, so D12 cannot be measured from post-side data.
