Marincess Deck #772426 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link and Xyz pressure from WATER Link Monsters (Azure Ocean Dragon Lord - Neo-Daedalus Rage, Levia-Dragoon - Daedalus) with Marincess / Umi / Atlantis support; Synchro and Xyz boards (Icejade Gymir Aegirine, LeVirtue Dragon, Xyz Armor Torpedo) once the Link base is established
• Turn 1 (going first): Open a starter (First Penguin, Trickstar Aqua Angel, Fish Sonar, Advent of Atlantis or Marincess Blue Tang), search an Umi/Atlantis piece, and extend into a WATER Link Summon
• Turn 2 (going second): Use the 15 hand traps (Ash Blossom, Infinite Impermanence, Evenly Matched, Droll & Lock Bird, Nibiru, Artifact Lancea) to disrupt the opponent's first board, then rebuild through Marincess and Umi searchers
• Recovery: Recover through Marincess Sea Angel, Marincess Blue Slug, Levia-Dragon / Atlantis recursion and Warchief of Atlantis from the GY; the deck has very few explicit recursion pieces left in the main deck list
• After siding: No Side Deck is registered, so there is no post-side plan; the build is fixed for every game of a best-of-3

Why it scores here

The deck is Illegal as registered: three copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of two, so the score is a theoretical, structural-only read and does not receive a normal Final Contextual score. The 56-card main deck has several reliable starters (First Penguin, Trickstar Aqua Angel, Fish Sonar, Advent of Atlantis, Marincess Blue Tang), and the hypergeometric estimate of at least one searcher-type card in a five-card opener is about 0.87, so the engine is reachable on paper. Interaction is the strongest part of the system: 15 hand traps and 13 negation-text cards give going-second disruption and layered protection. Consistency and conversion are held back by brick risk from 18 tech cards and low archetype purity (19.7% exact name), and by the absence of any recorded combo boards, so the median and ceiling output are text-only inferences. The score comes from the system (access, interaction, going-second disruption) and not from Marincess being a popular archetype, and the card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Toolbox secondary; the Midrange profile is applied as-is. Structural ≈ 53, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: illegal_copy_limit_cap (-16); banlist exposure (-2); no Side Deck (-2). Final formula: Illegal deck: theoretical/structural-only cap applied (Final = 0.80*Structural + 0.20*TournamentReliability would be about 51, capped to 35 for the copy-limit violation); Meta Power null (Provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• 15 hand traps and 13 negation-text cards give layered going-second interaction
• Several reliable starters (First Penguin, Trickstar Aqua Angel, Fish Sonar, Advent of Atlantis, Blue Tang) give multiple routes
• Extra Deck has multiple high-ATK Link and Xyz bosses

Weaknesses

• Illegal copy count on Ash Blossom & Joyous Spring (3 vs 2)
• No Side Deck, so no post-side plan
• Low archetype purity (19.7%) and 18 tech cards raise brick risk
• No recorded combo boards, so ceiling and median are unmeasured

Critical choke points

• Starter access depends on a small number of starters; P(>=1 Blue Tang in opener) is only about 0.25
• Link chains depend on specific Marincess/Umi pieces that are not fully present in the main deck

Recommended changes

Evidence & confidence

• Verified: Main deck 56 cards, Extra Deck 15 cards, Side 0 (within OCG size rules); Ash Blossom & Joyous Spring run at 3 copies against a Semi-Limited limit of 2; Droll & Lock Bird and Foolish Burial are Limited and each run at 1 copy
• Inferred: Starter access and consistency estimates from hypergeometric probabilities; Hand-trap and interaction quality from card text; Brick risk from tech density and purity
• Provisional: Meta Power is null because no dated metagame sample is supplied; Matchup fit (D13) is a placeholder
• Data gaps: No combos supplied, so combo 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 exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck registered, so post-side performance is unknown
