Gunkan Deck #768117 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Medium)

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

Legality

Main 40 / Extra 13 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz Summon a Gunkan Xyz (Shirauo-class Carrier, Ikura-class Dreadnought or Uni-class Super-Dreadnought) off Gunkan Suship Shari and Shari Red, then attack with the 2200-2900 ATK Xyz and use its on-summon draw and search effects; Fusion or Xyz beatdown from Garura, Mudragon, Starving Venom or Predaplant if the opening engine is interrupted
• Turn 1 (going first): Normal Summon Shari or Shari Red, use Unexpected Dai or Painful Decision to reach a second Gunkan piece, then Xyz Summon a Gunkan Xyz; Small World and Gunkan Suship Catch-of-the-Day supply searches
• Turn 2 (going second): Hold Shari Red as a negation or revive threat, use Raigeki or Change of Heart on the opponent's board when it matters, and rebuild through Ikura and Uni searches
• Recovery: Gunkan Suship Uni and Ikura search or summon further Gunkan pieces, and Catch-of-the-Day and Shirauo rebuild the Gunkan resource pool from hand and Deck
• After siding: Not evaluable: the deck runs no Side Deck, so no post-side plan exists in the evidence

Why it scores here

This list is Illegal: it runs 3 copies of Super Polymerization against a Semi-Limited limit of 2, so the score is structural-only and capped at 35. Structurally, the deck has a real Gunkan engine: Shari and Shari Red (3 copies each) give a 33.8% chance of at least one Shari starter in a 5-card opener, and Dai, Small World, Catch-of-the-Day, Ikura, Uni and Shirauo add searches and extra summon routes. Its Xyz Extra Deck (Shirauo-class Carrier, Ikura-class Dreadnought, Uni-class Super-Dreadnought, all 2 copies) gives a credible ceiling with direct-attack and draw effects. The deck has only 3 hand traps plus Raigeki and Change of Heart as interaction, with no side deck, so its floor and going-second plan are weak. Popularity of the Gunkan archetype in the usage stats confirms the list is real, not that it is strong. No card scores were averaged and no combo boards were recorded, so the ceiling is text-based.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-12); illegal-deck cap (-4.6). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 51.6; banlist exposure modifier -12 gives 39.6; illegal-deck cap sets final 35 (theoretical/structural-only)

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

• Three Gunkan Shari starters plus Shari Red give a consistent Shari-based opening
• Four Gunkan searchers/summoners (Uni, Ikura, Shirauo, Catch-of-the-Day) provide redundant routes
• Xyz Extra Deck gives credible closing pressure with 2200-2900 ATK and draw effects

Weaknesses

• Illegal: 3 copies of Super Polymerization exceed the Semi-Limited limit of 2
• No Side Deck, so no post-side adaptability
• Lava Golem and Raigeki are dead cards without an opponent board

Critical choke points

• Shari or Shari Red in hand or Deck: the engine depends on two Gunkan Shari-named monsters

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: 3 copies of Super Polymerization against a Semi-Limited limit of 2; Main 40, Extra 13, Side 0 within OCG size rules; P(>=1 Shari in a 5-card opener) = 0.3376 (hypergeometric); Gunkan archetype usage stat: core Shari and Unexpected Dai at 100% inclusion
• Inferred: Engine consistency from Shari and Shari Red plus Dai and searchers; Xyz ceiling from card text; Interaction density from Raigeki, Change of Heart, Shari Red negation and hand traps
• Provisional: Meta power and matchup fit: no dated metagame sample or tournament link; Going-first and going-second split: no recorded boards or win-rate telemetry
• Data gaps: no combos supplied, so floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot record are absent no win-rate telemetry in YGOVN for going-first/second, matchup or brick rates no Side Deck, so post-side plan cannot be assessed deck title is null
