Identity & game plan

Win condition: Link Summon a Link-4 or Link-2 Marincess board (Aqua Argonaut, Great Bubble Reef, Wonder Heart) and attack through a field that is locked or stripped of interaction; Recurring Marincess monsters from the GY through Link Summon triggers (Blue Tang, Springirl, Pascalus, Basilalima, Sea Horse) to rebuild the board
Turn 1 (going first): Open a WATER starter (Blue Tang, Springirl, Pascalus, Mandarin), search or excavate a Marincess Link-1/2 route, and Link Summon toward Link-4 while holding Wave or Lancea for the opponent's first interaction
Turn 2 (going second): Use Artifact Lancea as a hand trap or Marincess Wave to negate the opponent's first board, then rebuild from the GY via Springirl and Sleepy Maiden
Recovery: Banish Basilalima or Mandarin from the GY to re-enter Marincess monsters; Sea Horse and Pascalus recover Spells/Traps and rebuild the Link chain
After siding: No side deck is run (side 0), so there is no post-side plan; the deck cannot adapt between games

Why it scores here

The deck reliably opens a Marincess starter: the 19-copy archetype core gives a near-certain (≈0.997) chance of at least one Marincess card in a 5-card opening hand, although any single 3-copy starter appears only ≈43% of the time going first. Its strength is on the system rather than on card quality: 9 Link monsters in the Extra Deck feed Marincess recursion from the GY, so a board can be rebuilt after a single interruption. Interaction is layered across negation (Marincess Wave, Aqua Argonaut), removal-style text (Cascade, Mandarin, Basilalima), and three hand traps, which gives the end board some durability. The deck has no recorded boards, so the floor and median are text-only inferences and the ceiling is not averaged from card scores. Popularity (archetype usage stats) and the single guide only confirm that the list is real and accessible; they added no points, and no card scores were averaged into the deck score.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	62	P(≥1 of a 3-copy starter in 5 cards) ≈ 0.43 going first; archetype core 19 copies gives P(≥1) ≈ 0.997 (Inferred)
D2	Opening-Hand Quality & Brick Management	60	Full-brick proxy ≈ 0.003 from the core group; 12 level-0 spells/traps and 9 Extra-only Link pieces create some redundancy risk (Inferred)
D3	Combo Conversion & Ceiling	52	No parseable recorded boards; ceiling read from text of Aqua Argonaut (Link-4, 2300 ATK, negation text) and Great Bubble Reef (Link-4, 2600 ATK) (Inferred semantic)
D4	Combo Floor & Median Output	48	No combos_evidence median or power distribution is available, so the floor is inferred from starter diversity alone (Provisional)
D5	Interruption Resilience & Route Redundancy	66	Multiple GY recursion routes (Basilalima, Mandarin, Sea Horse, Sleepy Maiden) and 7 searcher-text cards give independent rebuild lines (Inferred)
D6	Resource Economy, Recovery & Grind	64	GY recursion and search text (7 searcher-text cards, Blue Tang and Pascalus excavation/recovery) support grind; no resource telemetry (Inferred)
D7	End-Board & Interaction Quality	70	3 hand traps (Lancea x3), 3 negation-text cards, 17 removal-text hints and Aqua Argonaut field lock give layered interaction (Inferred semantic)
D8	Going-Second & Board-Breaking Power	60	Going-second hand-6 probability for the 3-copy hand-trap group ≈ 0.50; Marincess Wave and Cascade break boards (Inferred)
D9	Offensive Pressure & Closing Power	66	End-board ATK from Link-4 monsters (2600/2400/2300) plus Battle Ocean's +200 ATK bonus; no damage telemetry (Inferred)
D10	Main Deck Efficiency & Flexibility	62	30 Main Deck cards, 16 distinct, 7 singletons; 18 Effect Monsters with several level-0 Spells/Traps adding flexibility (Inferred)
D11	Extra Deck Efficiency & Coverage	66	All 9 Extra slots used by Link monsters (8 distinct); Link access is limited by the Main Deck WATER monsters (Verified composition, Inferred access)
D12	Side Deck Adaptability	20	Side deck is empty (0 of 9 slots used) so there is no post-side adaptation (Verified composition)
D13	Matchup Coverage & Format Fit	50	No tournament_context or dated metagame sample, so archetype share is unavailable and fit is neutral (Provisional)
D14	Pilotability & Error Tolerance	50	Multi-step Link chains and many optional GY-trigger decisions raise pilot demands moderately; no step-count data (Inferred)

How the score was computed

Strategy profile: Midrange primary with Combo secondary (disclosed as a blend; weights taken from the Midrange profile). Structural ≈ 59, Going First ≈ 60, Going Second ≈ 57, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: No side deck (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*59 + 0.20*55 - 3 ≈ 55

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.43 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
Combo output: best PowerIndex —, median —, board-per-starter —
Turn order: 0 going-first lines vs 0 going-second lines

Strengths

Dense 19-copy archetype core gives near-certain access to some Marincess card in the opening hand
Recursion from the GY through several monsters and Link Summon triggers supports multi-turn rebuilds
Layered interaction with negation, field lock and three hand traps
All 9 Extra Deck slots are used, with Link-4 threats that have high ATK

Weaknesses

No side deck, so the deck cannot adapt across games
A single 3-copy starter is live going first only about 43% of the time
No recorded boards, so the combo floor and median cannot be measured
Heavy reliance on a Limited Link-4 (Wonder Heart) and on specific Link routes

Critical choke points

Link Summon requires WATER monsters on the field; losing them to a single removal can stall the chain
Going second, the hand-trap count is 3, so a turn-1 negation may not be available

Recommended changes

Priority	Remove	Add	Reason
1	Spell Shattering Arrow (1 copy)	Marincess Sea Angel (1 copy) or a second Marincess Blue Tang	Arrow is narrow removal against Spells; a starter or Link-1 route would raise the going-first starter rate
2	none (deck is already at 30 Main)	1–2 side-deck cards (e.g., a Spell/Trap answer)	A side deck would let the deck adapt between games; the current list has no post-side plan

Evidence & confidence

Verified: Legal: 30 Main (range 20–30), 9 Extra (range 0–9), 0 Side; Marincess Wonder Heart is Limited with 1 legal copy and 1 run; Core inclusion data: 19 archetype copies in the Main Deck
Inferred: Going-first and going-second starter probabilities (hypergeometric); Interaction and recursion quality from card text; Link-chain pilot complexity
Provisional: Meta Power is null: no dated metagame sample; Matchup fit (D13) is neutral pending a meta sample
Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
