Marincess Deck #760182 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link-engine Marincess board (Great Bubble Reef 2600 ATK, Marbled Rock 2500 ATK, Worldsea Dragon Zealantis 2500 ATK) built from hand starters and Link Summons, protected by a dense negation package; Recurring GY Marincess monsters through Blue Slug, Marbled Rock and Sea Angel search and Link Summon loops
• Turn 1 (going first): Open a Marincess starter (Springirl or Sea Horse once a Marincess is in GY, or Blue Tang or Pascalus) and Link Summon a Link-1 (Sea Angel or Blue Slug) to search; hold 1 or 2 hand traps (Ash Blossom, Ghost Belle, Maxx C) for the first opposing play
• Turn 2 (going second): Use hand traps (84 percent chance of at least one in a 6-card hand) to blank the opponent's first engine play, then continue through the same starters and Links
• Recovery: Rebuild from GY Marincess monsters via Blue Slug, Marbled Rock or Coral Anemone effects and use Dive or Battle Ocean to re-summon
• After siding: None: Side Deck size is 0, so there is no post-side plan at all

Why it scores here

The deck opens reliably enough on paper: the archetype core (22 copies) gives roughly a 93 percent chance of at least one core card in a 5-card opening hand, and five monsters can start from hand, though Springirl and Sea Horse need a Marincess already in the GY. Its strongest system trait is interaction density: about 15 negation-text cards, including Ash Blossom, Ghost Belle, Ghost Ogre, Maxx C, Droll and Lock Bird, and three Solemn cards, give layered responses on the opponent's turn. Conversion and closing are plausible on Link-3 and Link-4 bosses at 2500 to 2600 ATK, but no recorded boards exist, so the ceiling and median are text-only inference. The list is structurally weak in places: 14 hand traps and 25 tech or removal cards produce dead-hand risk, two floodgates (Gozen Match, Anti-Spell Fragrance) hit the deck's own board, and it has no side deck. Two Forbidden cards make the list illegal, so the score is capped low and labelled theoretical or structural only. The score reflects the system (consistency, interaction, resilience, closing) and not the average of individual card scores, and archetype popularity earned no points.

Dimension scores

How the score was computed

Strategy profile: Stun (meta-neutral: D13 dropped and weights renormalised over 86). Structural ≈ 54, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 46. Modifiers: banlist exposure (-6); engine conflicts (-3); weak post-side plan (-3). Final formula: Illegal list (2 Forbidden copies): no normal Final score. Reference uncapped value = 0.80*Structural(54) + 0.20*TournamentReliability(46) + modifiers(-12) = about 40, capped to 30 and labelled theoretical or structural-only. Meta Power provisional; no dated metagame sample supplied.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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 package: Ash Blossom x2, Ghost Belle x2, Ghost Ogre x2, Maxx C, Droll and Lock Bird, Solemn Judgment, Solemn Warning x2, Dominus Impulse x2
• Several hand-startable Marincess monsters give redundancy in the opening hand
• Link-1 searchers (Sea Angel, Blue Slug) and Blue Tang and Pascalus searchers support consistency
• Extra Deck covers Link-1 through Link-4 with high-ATK bosses

Weaknesses

• Illegal: two Forbidden copies (Triple Tactics Talent, Bahamut Shark)
• No side deck, so no post-side plan
• 14 hand traps and 25 tech or removal cards risk dead cards in hand
• Gozen Match and Anti-Spell Fragrance hinder the deck's own engine
• Low archetype purity (41.4 percent exact-name copies) and a bloated main deck of 32 distinct cards

Critical choke points

• A Marincess must be in the GY before Springirl or Sea Horse can be summoned from hand
• Link fodder must be available for every Link Summon
• Forbidden Triple Tactics Talent and Bahamut Shark must be removed before any legal play
• Gozen Match and Heavy Storm wipe the own board

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, with two Forbidden copies in the list (Triple Tactics Talent main, Bahamut Shark extra); Main 55, Extra 15, Side 0 against OCG size rules; Copy histogram 16 singletons, 9 doubles, 7 triples; Extra Deck: 13 Link and 2 XYZ; Probabilities: 0.93 archetype-core group in 5-card hand, 0.84 hand-trap in 6-card hand, 0.45 searcher in hand 5
• Inferred: Starter reliability and brick rate from hypergeometric estimates and card text; Interaction density and layering from negation text and the card list; Closing power from Link and XYZ ATK values combined with card text; Going-first and going-second scores from weighted dimension blends
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (no tournament link)
• Data gaps: No recorded combos: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry (going-first, going-second, matchup, brick or starter rates) Meta Power provisional: no dated metagame sample usage statistics in this deck flags disagree with the card list for several Extra Deck cards (Great Bubble Reef, Coral Anemone, Coral Triangle, Aqua Argonaut, Crystal Heart, Sea Angel); the card list was used as the source of truth, and the usage flags should be checked Marincess Mandarin appears in usage core stats but not in the card list; its legality is unknown
