Deck — Deck Power Evaluation

Final Contextual Deck Power: 63/100 (±6 · Confidence: Medium)

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

Legality

Main 27 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link Summon into a Link-4 Water field (Marincess Aqua Argonaut / Great Bubble Reef / Wonder Heart) and attack or sustain it behind hand-trap and negation backing; Recursion grind through Marincess GY effects (Pascalus, Mandarin, Sea Horse, Dive) to rebuild Link monsters after disruption
• Turn 1 (going first): Open a 2-card Water starter (Springirl, Blue Tang, Pascalus, Sea Horse or Mandarin), Special Summon into a Link-1 to Link-2 bridge, then Link Summon Aqua Argonaut or Great Bubble Reef while holding a hand trap (Effect Veiler, D.D. Crow, Forbidden Droplet) for the opponent's first interaction
• Turn 2 (going second): Use the 6-card hand to hold Effect Veiler or D.D. Crow for the opponent's main phase, then convert to the same Link-4 board; Marincess Wave and Droplet stop follow-up interaction
• Recovery: Banish Marincess monsters from the GY for their GY-triggered Special Summons and Link Summons, search Marincess Sea Angel / Blue Slug / Coral Triangle for the next Link
• After siding: Not applicable: Duel Links has no side deck, so there is no post-side plan

Why it scores here

The deck scores as a connected Marincess Link system, not as an average of its card scores. Its nine Water starters (two copies each of Springirl, Blue Tang and Pascalus, plus Sea Horse, Mandarin and Sleepy Maiden) give an estimated 0.89 chance of at least one starter in a 5-card opening hand (Inferred hypergeometric), which earns the high accessibility mark. Its 12 interaction cards (hand traps Effect Veiler, D.D. Crow, Forbidden Droplet and Marincess Wave, plus Aqua Argonaut's negation text) keep the Link-4 board alive through the opponent's first turn, which carries the endboard and going-second scores. Score is held back by the lack of any recorded combo boards (combo ceiling and median are text-only inferences), 3-copy non-engine cards that brick in a hand, and no meta-share or match telemetry, so Meta stays provisional. Meta-share and popularity did not earn points; the 'stable Link-4 fortress' claim in the guide is treated only as context.

Dimension scores

How the score was computed

Strategy profile: 0.85 Midrange / 0.15 Control (rounded, disclosed; Midrange weights used for the structural score). Structural ≈ 64, Going First ≈ 66, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: engine compactness (1); banlist exposure (-1); off-archetype dilution (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*64.1 + 0.20*62 - 1 = 62.7, rounded to 63

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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

• Nine Water starters with 2-copy redundancy give high Link-1 to Link-4 access
• Six hand traps plus Marincess Wave and Aqua Argonaut negation cover the opening turns
• Link-4 extra-zone monsters are immune to many effects, so the board survives single disruption
• Strong GY recursion through Marincess monsters supports grind

Weaknesses

• No recorded boards, so combo ceiling and median are unmeasured
• Three-copy non-engine cards (Droplet, Crow, Veiler) can be dead in a hand
• Off-archetype tech dilutes the Marincess engine (12 off-archetype copies)
• No side deck and no meta or matchup telemetry

Critical choke points

• Link-1 or Link-2 bridge from the first starter: losing Springirl or Blue Tang to a board breaker stalls the Link-4 route
• Single Wonder Heart (Limited-1) as the strongest Link bridge; running the copy lowers the ceiling if removed
• Hand-trap dependence on a going-second turn if the hand has no Veiler, Crow or Droplet

Recommended changes

Evidence & confidence

• Verified: Legal status: 27 main (20-30), 9 extra (0-9), Wonder Heart Limited-1 with 1 copy run; Archetype purity 66.7 percent and archetype spread; Usage statistics for core cards and inclusion percentages; Guide describes the Link-4 fortress and interaction plan as Vietnamese context
• Inferred: P(≥1 starter in 5) ≈ 0.89 from hypergeometric counts; P(≥1 hand trap in 6 going-second) ≈ 0.82; Link-4 fortress ceiling and hand-trap interaction density from card text; Going-first and going-second power estimates
• Provisional: Meta Power (null) and matchup fit (D13) lack a dated metagame sample; Median output (D4) and side adaptability (D12) lack recorded data
• 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 Data inconsistency: usage_statistics marks 8 core Extra-Deck cards (Sea Angel, Crystal Heart, Blue Slug, Coral Triangle, Wonder Heart, Great Bubble Reef, Aqua Argonaut, Coral Anemone) as in_this_deck=false and missing_core, but the cards list runs them at 1 to 2 copies each in zone=extra; core_present_pct 45.8 is therefore understated (corrected count 19/24 ≈ 79.2 percent)
