Marincess Deck #759430 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Tempo
• Format: duel-links

Legality

Main 30 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link-4 boss monsters (Marincess Aqua Argonaut, Marincess Wonder Heart, Marincess Great Bubble Reef) built from a Link-based WATER engine, supported by Marincess Battle Ocean's ATK boosts; Recursion-driven Link Summons and resource replacement through Marincess Sea Horse, Pascalus, Basilalima and Ghost Belle from the GY
• Turn 1 (going first): Open Springirl, Blue Tang and Basilalima/Pascalus searchers to reach a Link-1 or Link-2 floor, then Link Summon toward Argonaut or Great Bubble Reef while holding Wave and Ghost Belle or Ghost Ogre for the opponent's response
• Turn 2 (going second): Use the 5 hand traps (3x Ghost Belle, 2x Ghost Ogre) and Marincess Wave to break the opponent's first board, then rebuild the Link engine from the GY via Sea Horse and Pascalus
• Recovery: Recycle WATER monsters from the GY through Sea Horse, Sea Angel, Blue Slug and Coral Anemone, and reuse Ghost Belle's GY effects to add or Special Summon monsters
• After siding: Not applicable: the deck runs zero side cards, so there is no post-side plan (Duel Links allows 0 to 9)

Why it scores here

The deck reliably opens a functional Marincess engine: three Springirl and three Blue Tang give roughly a 43% chance of at least one of each in a 5-card opening hand (Inferred hypergeometric estimate), and five searcher-text cards add redundant access to the Link-1 and Link-2 floor. Its conversion ceiling comes from Link-4 bosses (Aqua Argonaut, Wonder Heart, Great Bubble Reef) that the card text describes as resistant to opposing effects, supported by Battle Ocean's ATK boosts. Interaction is layered across five hand-trap-style cards, Wave, Cascade and the Link monsters' negation text, and the GY recursion (Sea Horse, Pascalus, Ghost Belle) lets the deck continue after one disruption. Points were not earned from the archetype's usage share or from averaging card scores; the score reflects the system's consistency, recursion and interaction, and the absence of a side deck and of any recorded combos holds it back.

Dimension scores

How the score was computed

Strategy profile: Midrange profile weights, with D13 kept but provisional. Structural ≈ 62.4, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: No side deck (-3); Off-archetype Mulcharmy copies (-1); Banlist exposure (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*62.4 + 0.20*58 = 61.5, then -4 modifiers = 57.5, rounded to 58

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.43 · 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

• Engine has redundant searchers (5 searcher-text cards) and multiple Link routes
• Five hand traps give strong going-second interaction, reaching about 70% in a 6-card hand
• Link-4 bosses have high ATK and resist opposing effects per card text
• GY recursion (Sea Horse, Pascalus, Ghost Belle) recovers the engine after disruption
• Legal list with no violations; the Limited card is run at its legal count

Weaknesses

• No side deck, so no post-side adaptation in best-of-3
• Four Mulcharmy cards and seven generic off-archetype copies lower engine coherence
• Mulcharmy Fuwalos and Purulia depend on an empty field to activate
• No recorded combos, so the floor and median are text-only inference
• Marincess Battle Ocean has only one copy against a typical copy count of 2

Critical choke points

• Battle Ocean and the Link-1 or Link-2 floor depend on one of Springirl or Blue Tang being drawn, roughly 43% in a 5-card hand
• Link-4 conversion needs the WATER Link route to stay intact through the opponent's first response

Recommended changes

Evidence & confidence

• Verified: Main 30, Extra 9, Side 0 are within Duel Links limits (main 20 to 30, extra 0 to 9, side 0 to 9); Marincess Wonder Heart is Limited with one legal copy, and the deck runs one; Copy histogram 1x10, 2x1, 3x6 and archetype purity of 71.8% (exact name); Battle Ocean typical copies 2 versus 1 in the deck (usage statistics); Guide snippet describes a stable Link-4 engine around Aqua Argonaut
• Inferred: Opening-hand estimates of 0.4335 for 3-copy cards (5-card hand) and 0.7017 for hand traps (6-card hand); Ceiling and floor reads from card text (no recorded boards); Going-first and going-second strength from hand-trap and recursion text; Interaction breadth from negation and removal text
• Provisional: Meta Power (null) and d13 matchup fit, since no dated metagame sample or tournament link exists; Going-second versus going-first split
• 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 are absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Data inconsistency: usage_statistics marks Marincess Aqua Argonaut, Great Bubble Reef, Coral Anemone, Crystal Heart, Coral Triangle, Blue Slug, Sea Angel and Wonder Heart as absent (copies_in_deck 0) even though the cards array lists them in the Extra Deck, so core_present_pct (52.4) is unreliable
