Identity & game plan

  • Win condition: Extra Deck WATER bosses: Abysstrite, Poseidra Abyss, Icejade Gymir Aegirine, Swordsoul Supreme Sovereign - Chengying, White Aura Whale and Monoceros; Level 7 WATER Synchro/Xyz boards backed by Mermail Abyssgaios negation and Coelacanth
  • Turn 1 (going first): Search Neptabyss, Abyssteus, Atlantean Dragoons or Poseidra for the Level 7 / Level 4 WATER base, then Synchro or Xyz into a 2800-3000 ATK boss, using Abyssrhine as a tribute or search engine
  • Turn 2 (going second): Reset the board with Raigeki, Lightning Storm, Feather Duster or Forbidden Droplet, or stop it with Infinite Impermanence, then rebuild through the GY-recursion and searcher chains into a boss
  • Recovery: GY recursion: Mermail Shadow Squad, Mermail Abysspike, Deep Sea Aria and Atlantean Dragoons return searchers and tuners from the Graveyard, while the 15-card Extra Deck is rebuilt from the surviving WATER monsters
  • After siding: None: the deck runs zero side-deck cards, so there is no post-side plan

Why it scores here

The deck reliably opens a functional plan: 16 searcher-text copies give roughly a 93.5% chance of at least one searcher in a 5-card opening hand, and only about 6.5% of such hands lack one (Inferred). Conversion rests on a 15-card Extra Deck of Synchro, Xyz and Link bosses, but only three main-deck tuners plus Deep Sea Prima Donna are available for six Synchro monsters, and no recorded boards exist to confirm the ceiling or median. Interaction is real (Raigeki, Lightning Storm, Feather Duster, Forbidden Droplet, Infinite Impermanence, Virtue Stream, Abyss-sting Triaina) and carries the going-first and going-second plans, but the list has zero side-deck cards, so there is no post-side plan to earn points on. Usage statistics confirm the archetype is real and accessible and show the list skips high-inclusion staples such as Atlantis, City of the Sea Dragon (69%), but popularity earned no points, and card scores were not averaged into the deck score. The result is 60 +/-6 at Medium confidence, with Meta Power left provisional.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 72 P(>=1 searcher-text card in 5) ~0.935 and P(>=1 starter-group card in 5) ~0.919; Synchro access is bottlenecked by only three main-deck tuners plus Deep Sea Prima Donna (Inferred)
D2 Opening-Hand Quality & Brick Management 68 About 6.5% of going-first 5-card hands lack a searcher; 13 single-copy slots, including tech singles, raise brick risk (Inferred)
D3 Combo Conversion & Ceiling 68 No parseable boards; the ceiling is read from card text only, through Abysstrite, Poseidra Abyss, Icejade Gymir and Chengying boards with negation support (Inferred)
D4 Combo Floor & Median Output 60 No recorded boards, so floor and median are unknown and placed conservatively at 60 (Provisional)
D5 Interruption Resilience & Route Redundancy 70 Five starter or searcher species plus Graveyard recursion (Shadow Squad, Abysspike, Dragoons, Aria) give several independent lines after disruption (Inferred)
D6 Resource Economy, Recovery & Grind 66 Searcher chains and GY recursion regenerate resources, but the 15 Extra Deck bosses form a finite base (Inferred)
D7 End-Board & Interaction Quality 74 Six interaction spells and traps (Raigeki, Lightning Storm, Feather Duster, Forbidden Droplet, Infinite Impermanence, Virtue Stream) plus negation text on Mermail Abyssgaios and Coelacanth (Inferred)
D8 Going-Second & Board-Breaking Power 66 Going-second hand-6 P(>=1 starter) ~0.954 and Droplet, Impermanence and Duster help against an established board; no going-second split data exists (Inferred)
D9 Offensive Pressure & Closing Power 72 Extra bosses at 2800-3000 ATK: Poseidra Abyss 3000, Icejade Gymir 3000, Chengying 3000, White Aura Whale 2800, Coelacanth 2800 (Verified card stats)
D10 Main Deck Efficiency & Flexibility 62 40 main cards with 24 distinct; 13 singles and 2 Limited singles dilute consistency; 27 main-deck monsters (Verified composition)
D11 Extra Deck Efficiency & Coverage 64 15 Extra: 6 Synchro, 6 Xyz, 3 Link; the Synchro slots are tuner-limited while Xyz access is flexible (Verified composition, Inferred)
D12 Side Deck Adaptability 15 Zero side-deck cards, so there is no post-side plan (Verified)
D13 Matchup Coverage & Format Fit 50 No tournament link and no dated meta sample; neutral placeholder of 50 (Provisional)
D14 Pilotability & Error Tolerance 60 Multi-step Synchro and Xyz lines with Mermail effect sequencing give several decision points per turn (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 64.6, Going First ≈ 71, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: Tuner-bottlenecked Synchro engine (-2); No side deck (-2); WATER monotype coherence (1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*64.6 + 0.20*56 - 3 = 59.9, rounded to 60

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Searcher density: 16 searcher-text copies give about 93.5% odds of a searcher in a 5-card opening hand (Inferred)
  • Extra Deck of 15 boss monsters at 2800-3000 ATK across Synchro, Xyz and Link
  • Six interaction spells and traps plus negation text, giving layered answers for both turns
  • Legal in OCG; only two single-copy Limited cards, each run at its legal limit

Weaknesses

  • Zero side-deck cards, so no post-side adaptation
  • Synchro bottleneck: six Synchro monsters against three main-deck tuners plus Deep Sea Prima Donna
  • Low exact archetype purity (23.6%) with staple gaps: Atlantis, City of the Sea Dragon (69% usage inclusion) is absent
  • No recorded boards to verify the combo ceiling or median

Critical choke points

  • Going-first 5-card hand with no searcher (about 6.5%)
  • Tuner availability for Synchro summons
  • Two Infinite Impermanence as the only single-card answer to a face-up monster before the Extra Deck comes online
Priority Remove Add Reason
1 A side deck of up to 15 cards covering the matchups the list expects to face Zero side cards removes all best-of-3 adaptation; D12 is the weakest dimension (Verified)
2 1 Abyss-sting Triaina A third WATER Tuner Six Synchro monsters need tuners and only three main-deck tuners exist; Triaina is a single-copy Spell that adds no tuner access (Inferred)

Evidence & confidence

  • Verified: Legal in OCG with 40 main and 15 Extra cards, zero side cards; Harpie's Feather Duster and One for One are Limited at 1 copy each, run at the legal limit; 16 searcher-text copies and 13 removal-text copies counted from card text; Usage statistics available: 36 rows, Atlantean archetype core-card inclusion
  • Inferred: P(>=1 searcher in 5-card opening) ~0.935 and P(>=1 starter) ~0.919 (hypergeometric); Interaction density and negation layering from card text; Synchro tuner bottleneck from the Extra Deck and main-deck tuner count; Going-first and going-second scores from the dimension inputs
  • Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (placeholder 50, no tournament link)
  • Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry in YGOVN for going-first/second, matchups, brick or starter rates Meta Power is provisional without a dated metagame sample Usage statistics 'in this deck' flags look main-deck-only: Abysstrite, Mermail Abyssgaios, LeVirtue Dragon, Poseidra Abyss, Marincess Coral Anemone and Icejade Gymir are in the Extra list but flagged false, so core-card presence (28%) is unreliable and extra-deck core inclusion was not scored from it Deck has no title (null), so the deck name is unknown
