Marincess Deck #690152 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Link Summon Marincess Link monsters (Coral Anemone, Marbled Rock, Great Bubble Reef, Aqua Argonaut) and convert board presence into attacks and banish-based pressure; Link Summon Worldsea Dragon Zealantis or Shootingcode Talker as a late-game board breaker, plus Mulcharmy and hand-trap disruption
• Turn 1 (going first): Open Marincess starters (Springirl, Sea Horse, Blue Tang, Pascalus) and Cynet Mining for a Link-1 or Link-2 base, then extend into a Link-3 or Link-4 Marincess monster
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Effect Veiler, Infinite Impermanence and Red Reboot to negate the opponent's first summon or board, then rebuild from the GY via Marincess recursion
• Recovery: Recycle Marincess monsters and Spells from the GY through Blue Slug, Sea Angel, Marbled Rock and Coral Triangle effects
• After siding: No side deck is registered, so no post-side plan can be evaluated

Why it scores here

The deck reliably opens a Marincess starter: three copies each of Springirl, Sea Horse, Blue Tang and Pascalus give roughly a 32% chance of at least one in a 5-card opening hand, and the archetype core group reaches about 90% for at least one core card. Its interaction is the strongest part of the list, with 12 hand traps and about 15 negation-text and 14 removal-text cards giving a 0.89 chance of at least one hand trap on a going-second 6-card hand. Recursion through the Marincess GY effects and several Link monsters supports resilience, but there are no recorded combos, so the conversion and median scores rest on text reading only. The score is capped low because the list is Illegal: two Forbidden cards (Called by the Grave and Triple Tactics Talent) are run, and no side deck is registered. Popularity was not rewarded, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 63, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-12). Final formula: Structural 57 and TournamentReliability 52 give 0.80*57 + 0.20*52 = 56, minus 12 for banlist exposure = 44; Illegal deck capped to 25 (theoretical/structural-only), Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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-copy Marincess starters give a reliable opening rate
• Dense hand-trap and negation package with strong going-second interaction
• Link-based recursion gives a real route after disruption
• Broad Extra Deck coverage from Link monsters

Weaknesses

• Two Forbidden cards make the list Illegal as built
• No side deck registered
• No recorded combos, so the ceiling and median are unmeasured
• Tech density dilutes the core (Called by the Grave and Triple Tactics Talent)

Critical choke points

• Marincess Blue Tang and Springirl access, since most lines depend on a 4-level Marincess starter
• Link Summon chain depends on specific Link-1 and Link-2 monsters (Blue Slug, Sea Angel, Crystal Heart)

Recommended changes

Evidence & confidence

• Verified: Two Forbidden cards (Called by the Grave, Triple Tactics Talent) run in the main deck; Main 42 and Extra 15 are within OCG size limits; Limited and Semi-Limited copy limits are respected; Archetype purity 56.1% exact-name Marincess
• Inferred: P(at least one 3-copy starter in 5 cards) ≈ 0.32; Core archetype group ≈ 0.91 for one in hand; Hand-trap access on going-second 6-card hand ≈ 0.89; Interaction density rated high from card text
• Provisional: Meta power and format fit (no dated sample or archetype share)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry for OCG; going-first, matchup and brick rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered
