• Format: tcg

Legality

Main 45 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz Summon a Gunkan or Ryzeal boss (Ryzeal Detonator 3000 ATK, Gunkan Suship Uni-class Super-Dreadnought 2900 ATK, Ikura-class Dreadnought 2200 ATK) from a Shari-based opening, then press with the resulting board.; Extend off Ryzeal and Gunkan Xyz with Ice/Sword Ryzeal and Node Ryzeal bodies, backed by 1-of disruption (Raigeki, Lightning Storm, Harpie's Feather Duster).
• Turn 1 (going first): Turn 1: Gunkan Suship Shari or Painful Decision/Primite Lordly Lode to find a Shari or Gunkan enabler, Special Summon Gunkan Suship Uni or Shari Red, and build toward a Gunkan or Ryzeal Xyz Summon on turn 2.
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Nibiru or Primite Drillbeam to stop the opponent's first engine or board, then Xyz or Link Summon from the resulting board.
• Recovery: Searchers (Painful Decision, Bonfire, Ext Ryzeal, Gunkan Suship Ikura, Gunkan Suship Catch-of-the-Day) and Ryzeal Cross recursion rebuild a starter after a broken hand; Ryzeal Plugin and Ice Ryzeal reuse Ryzeal bodies from the GY.
• After siding: No Side Deck is registered (side_count 0), so there is no post-side plan; any adjustment is limited to replacing Main Deck cards.

Why it scores here

The deck reliably opens its Gunkan and Ryzeal starters: 15 archetype-core copies give an estimated 0.88 chance of at least one in a 5-card opening hand (Inferred), and 15 searcher-text cards add redundancy. It converts those openings into Xyz bosses at 2200-3000 ATK, and its interaction package (6 hand traps, 12 negation-text cards and 6 removal-text cards) gives it real end-board and going-second value. Its weaknesses are the 26.7% exact-archetype purity, which mixes Gunkan, Ryzeal, Primite, Utopia, Mulcharmy and generic tech into one engine, and the 1-of Raigeki, Lightning Storm and Harpie's Feather Duster slots, which can be dead in openings. No combos were supplied, so the median and ceiling reads are text-based and Inferred. Popularity was not credited; the score comes from consistency, interaction and closing power on the system, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 62, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-2); weak post-side plan (-2); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers (-6)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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

• Archetype core is dense: 15 copies with ~0.88 chance of at least one in an opening hand
• Six hand traps and about 12 negation-text cards give layered going-second interaction
• Extra Deck closers reach 2900-3000 ATK, with several Xyz routes from the same Shari/Ryzeal material

Weaknesses

• Low exact-archetype purity (26.7%) spreads the engine across Gunkan, Ryzeal, Primite, Utopia and Mulcharmy
• Several one-of situational cards (Raigeki, Lightning Storm, Harpie's Feather Duster, Bonfire) can be dead in an opening
• No Side Deck registered, so the list cannot adapt between games

Critical choke points

• The Shari or Gunkan enabler in hand, because Xyz boss access depends on it (verified in card text)
• Ryzeal Detonator and Ext Ryzeal are single copies at the Limited cap, so losing them to disruption removes a closing route

Recommended changes

Evidence & confidence

• Verified: Legal status: 45 Main, 15 Extra, 0 Side, all copy limits respected; Banlist statuses for Limited and Semi-Limited cards; Archetype purity and composition counts
• Inferred: Archetype-core opening probability (0.88) and hand-trap probability (0.60); Interaction and closing-power reads from card text; Structural and final score
• Provisional: Meta power (no dated metagame sample); Matchup fit (no tournament data); Post-side plan (no Side Deck)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck registered (side_count 0)
