Marincess Deck #770161 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link Summon Marincess Link monsters (Coral Anemone, Marbled Rock, Aqua Argonaut, Great Bubble Reef, Zealantis) into boss-size attackers, with Battle Ocean boosting Marincess ATK; Synchro/XYZ boss (Icejade Gymir Aegirine 3000 ATK, Stealth Kragen) and Marincess recursion from the GY to rebuild Link material
• Turn 1 (going first): Turn 1: Special Summon Marincess Springirl or Sea Horse from hand, use Cynet Mining or Blue Tang to set up searchers and the Link-2/3 engine; Link Summon Marincess Blue Slug or Sea Angel to search a Marincess spell or monster
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Dominus Impulse and Marincess Wave for the opponent's Special Summons and activations, then rebuild through Pascalus and Dive from the GY
• Recovery: Banish Marincess Mandarin or Blue Slug from the GY to re-enter Link material, use Marincess Dive or Pascalus to recur monsters, and rebuild the Link chain on the next turn
• After siding: No side deck is registered, so no post-side plan can be evaluated; any sideboarding would be a new build

Why it scores here

The score is a structural read of the list as a system and is capped low because the list is illegal: Ash Blossom and Dominus Impulse are each run three times against a Semi-Limited limit of two. The deck reliably opens a Marincess starter, since the archetype core has a proxy hypergeometric chance of about 0.98 of at least one card in a five-card opening hand. Its engine converts through Link Summons into strong boss-size attackers (Marbled Rock 2500, Zealantis 2500, Gymir 3000), and its hand-trap suite gives it real going-second interaction. It survives disruption through Marincess recursion from the Graveyard (Dive, Pascalus, Blue Slug, Mandarin). However, there is no combo data, no side deck, no tournament link and no win-rate telemetry, so combo floor and matchup fit remain inferred or provisional. Popularity was not credited and card scores were not averaged; the score comes from consistency, interaction and recovery on the system.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56.5, Going First ≈ 58, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-4). Final formula: Illegal list: theoretical/structural-only. Uncapped 0.80*Structural(56.5)+0.20*TournamentReliability(45)=54.2, then modifiers, then capped to 35 for copy-limit violations (Ash Blossom x3 and Dominus Impulse x3 vs legal 2); Meta Power null (Provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Consistent Marincess starter density (3-copy staples)
• Strong Link end-board attackers (Marbled Rock, Zealantis, Gymir)
• Layered hand-trap and negation suite for going second
• Graveyard recursion for resilience

Weaknesses

• Illegal copy limit on Ash Blossom and Dominus Impulse
• No side deck
• Two core Extra Deck Links (Great Bubble Reef, Coral Triangle) missing
• Single-copy spells (Dive, Mandarin, Wave, Sleepy Maiden) add dead-draw risk

Critical choke points

• Illegal copy count must be fixed before the list can be competitively evaluated
• Link Summon chain depends on a few Link-2/3 monsters (Coral Anemone, Marbled Rock) in the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Main deck 40 cards and Extra deck 15 cards are within OCG size rules; Ash Blossom and Dominus Impulse are each run 3 times against a Semi-Limited limit of 2 (Illegal); Monster Reborn is Limited and run at 1 copy (legal); Exact Marincess name purity is 60 percent; Core Extra Deck Links Great Bubble Reef and Coral Triangle are absent
• Inferred: Starter consistency from hypergeometric odds (0.98 archetype core proxy; 0.65 hand trap in hand 6); Link route coverage and recursion resilience from card text; Going-second interaction from hand-trap and negation text; Scores for D1 to D14 from composition and card text
• Provisional: Meta Power (no dated metagame sample); Matchup fit and tournament reliability (no tournament link)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No side deck registered: post-side plan cannot be evaluated No win-rate telemetry (going-first/second, matchup, starter or brick rates) Meta Power is Provisional until a dated metagame sample is supplied
