Marincess Deck #767176 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 46 / Extra 18 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Poseidra Abyss, Neo-Daedalus Rage, Abysstrite, Mermail Abyssgaios) reached through the Atlantean/Umi engine; Synchro and Xyz beatsticks (White Aura Whale, Icejade Gymir Aegirine, Swordsoul Supreme Sovereign) once the board is established
• Turn 1 (going first): Open on a searcher-heavy hand (P(at least one searcher in 5) ≈ 0.91), summon a 1-card starter such as Neptabyss or First Penguin, and bridge into Atlantis/Umi Level-based Synchro or Xyz summons. Requires an unverified combo path because no boards were supplied (Inferred).
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Maxx "C", and Dominus Impulse as interaction in a six-card hand (P(at least one hand trap in 6) ≈ 0.44), then rebuild through searchers. Inferred from card text only.
• Recovery: Rebuild from the Graveyard through Warchief of Atlantis, Atlantean Dragoons, and Sea Stealth/Umi effects that add or recycle monsters. Inferred from card text only.
• After siding: No side deck is registered, so no post-side plan can be evaluated. The deck is illegal as built and would need a side deck to be legal in best-of-3 play.

Why it scores here

This deck is scored as a connected Atlantean/Umi system, not as an average of its card scores. Its consistency is moderate: the searcher density is high (P(at least one searcher in a 5-card opening hand) ≈ 0.91), but the core engine copies are only 2–3 each and 21 of 32 distinct main-deck cards run a single copy, so the bridge from starter to engine is fragile (Inferred). Interaction is the most credible strength: four hand traps, Dominus Impulse, Ice Barrier, and several negate and removal texts give it layered answers. Conversion and median output cannot be measured because no recorded boards exist, so the ceiling and floor are text-only inferences. Popularity did not earn points: the archetype label is Marincess, but only one card carries that exact name, and the core Marincess cards are absent, so the deck is not the archetype-standard list. The deck is illegal as built (two Forbidden cards, Extra Deck of 18 against a limit of 15), which caps the final score and makes it a structural-only read.

Dimension scores

How the score was computed

Strategy profile: 0.7 Midrange / 0.3 Combo. Structural ≈ 44, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-6); extra_deck_over_limit (-3); illegal_deck_cap (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*44 + 0.20*35 - 12 ≈ 30 (Meta provisional; illegal-deck cap applied)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.3 · 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

• Dense searcher text (17 cards) gives high odds of finding an engine piece
• Layered interaction: four hand traps plus Dominus Impulse, Ice Barrier, Maxx "C", and Droll & Lock Bird
• Multiple high-ATK Extra Deck bosses across WATER Synchro, Xyz, and Link routes

Weaknesses

• Illegal as built: two Forbidden cards and 18 Extra Deck cards against a 15-card limit
• No side deck, so no post-side plan and no answer to matchup problems
• Engine coherence is weak: 1.6% exact-name Marincess purity, with 21 of 32 main cards single-copy
• No recorded boards, so the combo ceiling and floor are unmeasured

Critical choke points

• Starter access depends on one or two copies of each engine card, so a single dead opening hand is hard to recover
• Extra Deck over the limit means at least three cards must be cut before the deck is playable

Recommended changes

Evidence & confidence

• Verified: Illegal status: Bahamut Shark and Barrier Statue of the Torrent are Forbidden in OCG; Extra Deck count is 18 against a maximum of 15; Main deck is 46 cards, within the 40–60 range; No side deck is registered; Searcher-text count of 17 and copy histogram come from the evidence pack
• Inferred: Opening-hand and draw odds (hypergeometric estimates); Starter and engine consistency; Interaction breadth from card text; Going-first and going-second estimates from card text
• Provisional: Meta Power is null: no dated metagame sample is supplied; D13 format fit is provisional without a tournament link
• Data gaps: No combos supplied: floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry for OCG: going-first, going-second, matchup, and brick rates are Inferred or Unknown No side deck registered Meta Power is Provisional unless a dated metagame sample is supplied
