Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 52 / Extra 20 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link-4 and Link-3 Marincess/WATER monsters attacking, with Marincess Battle Ocean ATK boosts and high-ATK Link monsters such as Azure Ocean Dragon Lord - Neo-Daedalus Rage (2900 ATK) and Marincess Wonder Heart (2400 ATK) (Inferred from card text and stats); Xyz pressure from Number 103: Ragnazero and Stealth Kragen-style board removal, only if the Extra Deck is trimmed to a legal 15 (Inferred)
• Turn 1 (going first): Open a Marincess starter (Springirl, Sea Horse, Blue Tang or Sleepy Maiden), search with Cynet Mining or Blue Tang, then Link Summon through Marincess Sea Angel or Marincess Blue Slug (Inferred from text; no recorded boards)
• Turn 2 (going second): Use Ash Blossom & Joyous Spring, Nibiru, Marincess Wave or Call of Atlantis to break the opponent's first action, then rebuild through Link Summons (Inferred)
• Recovery: Banish Marincess monsters from the GY for revival and use Marincess Dive to Special Summon a non-Link Marincess monster from the GY (Inferred from the excerpts)
• After siding: None: the deck has 0 Side Deck cards, so there is no post-side plan (verified from legality counts)

Why it scores here

This list is illegal in TCG because the Extra Deck holds 20 cards against a maximum of 15, so it receives a structural-only read capped at 30 rather than a normal Final Contextual score. The structural read comes from the system, not from averaging card scores: the Marincess core (24 copies, P(at least one in a 5-card opening hand) about 0.96, Inferred) gives reliable access to starters, and the Link-heavy Extra Deck supplies high-ATK closers. Five hand traps and 8 negation-text cards add interaction, and 16 searcher-text cards support recovery. Archetype popularity and the 100% usage stats for core cards confirm the list is real and accessible, but they earned no points by themselves. The deck has no recorded boards, no tournament link, and no Side Deck, so the combo ceiling, median output and post-side scores are text-only estimates.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 60, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Illegal Extra Deck size (20 > 15) (-12); Engine dependence on Link-Summon chain (0). Final formula: Illegal cap: structural-only. Unmodified no-meta blend = 0.80*58 + 0.20*48 = 56, then modifiers (-12, total -26 applied through the illegal cap) => 30. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense archetype core: 24 Marincess-named copies give high starter access
• Redundant starters and searchers (16 searcher-text cards)
• Several interaction routes: 5 hand traps, Marincess Wave, Call of Atlantis, Ash Blossom x2
• High-ATK Link-4 closers

Weaknesses

• Illegal: Extra Deck is 20 cards against a maximum of 15
• Low exact-archetype purity (43.1%) across 9 related sub-archetypes
• No Side Deck (0 cards)
• No recorded combos, so ceiling and floor are unmeasured

Critical choke points

• Link Summon chain: most Marincess lines need a Link-1 or Link-2 base (Sea Angel, Blue Slug, Crystal Heart, Coral Anemone) to be live
• Extra Deck legality: until five Extra cards are cut the list cannot be played in a legal event

Recommended changes

Evidence & confidence

• Verified: Main 52, Extra 20, Side 0; Extra exceeds the TCG limit of 15; Ash Blossom & Joyous Spring is Semi-Limited at 2 copies, which is legal at 2; Copy histogram 8 one-of / 4 two-of / 12 three-of; Core cards are at 100% usage in the archetype stats; 12 of 25 core cards are present
• Inferred: P(at least one core Marincess card in a 5-card hand) ≈ 0.96; Brick proxy ≈ 0.04; Engine plans, interaction routes and recovery plans derived from card text; Structural scores and the -12 Extra-size modifier
• Provisional: Meta power (null); Matchup fit and tournament reliability; Going-first and going-second splits
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta share and pilot match record are absent No win-rate telemetry for going-first/second, matchup, brick or OTK rates Meta Power is provisional unless a dated metagame sample is supplied Deck is illegal (Extra 20 > 15); the score is a capped structural-only read No Side Deck, so post-side scoring is unavailable
