Legality
Main 52 / Extra 13 / Side 0 — status: Illegal. 7 violation(s).
Identity & game plan
- Win condition: Board pressure from Atlantean, Mermail and Abyss-named Xyz/Synchro/Link monsters (Poseidra Abyss, Abysstrite, Mermail Abyssgaios) and Deep Sea boss-level monsters; Floodgate and hand-trap pressure (Barrier Statue, Gozen Match, Droll and Lock Bird) to lock the opponent's summons
- Turn 1 (going first): Search a Mermail or Atlantean searcher through Neptabyss, Mermail Abyssteus, Abysspike or Dragoons, then extend into a Level 7 Xyz or Synchro boss; floodgate is not a reliable T1 play
- Turn 2 (going second): Hold hand traps (Ash Blossom, Evenly Matched, Droll, Dominus Impulse) for the opponent's first summon, then convert with the surviving searcher line
- Recovery: Recover through searchers that add a new starter from the Deck, plus Atlantean Heavy Infantry and Butterfly Fish as GY recursion
- After siding: Not evaluable: the list has zero Side Deck cards, so there is no post-side plan
Why it scores here
The deck is Illegal in TCG: four Forbidden cards (Barrier Statue of the Torrent, Called by the Grave, Triple Tactics Talent, Gozen Match) are run, and Ash Blossom, Dominus Impulse and Droll & Lock Bird exceed their copy limits, so the score is a theoretical, structural-only read capped at 25 and does not represent a playable deck. Structurally it opens reliably: 14 searcher-text cards give an estimated P(at least one searcher in a 5-card opening hand) of about 0.81 (Inferred), and 8 hand traps give about 0.65 chance of at least one in a 6-card going-second hand (Inferred). Its weaknesses are its spread: only 5 cards (7.7%) are the exact Abyss- archetype name, 60 of 65 copies are off-archetype across Atlantean, Mermail, Mulcharmy, Dominus and other sub-archetypes, and no sideboard exists. The score comes from consistency and interaction on the system, not from the Abyss- name or from averaging the individual card scores. Without combo data, median and ceiling output are text-only inference.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 66 | P(>=1 searcher in 5-card hand) about 0.81 across 14 searcher-text cards; 2-card bootstrap plausible (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Redundant searchers but mixed sub-archetypes and 16 single-copy slots raise conflicting-summon and brick risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | Text-only read of Abysstrite, Poseidra Abyss and Mermail Abyssgaios boards; no recorded combos supplied (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No parseable boards, so floor and median are not measured and are estimated conservatively (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 60 | 8 hand traps and multiple searchers give independent recovery routes after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Searchers and GY recursion (Atlantean Heavy Infantry, Butterfly Fish) regenerate resources, with no measured netCardAdvantage (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Ash Blossom, Dominus Impulse, Evenly Matched, Virtue Stream and Droll give layered interaction; semantic read only (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 55 | Going-second hand-trap coverage is strong, but board-breaking depends on Forbidden floodgates that are illegal here (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Multiple Level 7 to 10 bosses at 2800 to 3000 ATK (Poseidra Abyss, Icejade Gymir, Adamancipator Dragite) give closing power (Verified stat) |
| D10 | Main Deck Efficiency & Flexibility | 40 | Exact-name purity is 7.7% and 60 of 65 copies are off-archetype across 15 archetypes, with 4 Forbidden and 3 over-limit slots (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 13 Extra cards across Xyz, Synchro and Link with multiple mandatory-looking Atlantean and Mermail summon routes (Inferred) |
| D12 | Side Deck Adaptability | 10 | Zero Side Deck cards, so no post-side adaptability exists (Verified) |
| D13 | Matchup Coverage & Format Fit | 35 | No tournament link, archetype share or dated meta sample; Forbidden cards also remove format fit (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multi-engine decision tree with many hand-trap timing choices is demanding for a repeatable pilot (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-10); engine conflicts (-2). Final formula: Illegal cap: min(0.80*Structural + 0.20*TournamentReliability + ContextModifiers, 25); Meta provisional. Pre-cap 52*0.80 + 48*0.20 - 12 = 39.2, capped to 25
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.81 · 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
- 14 searcher-text cards make a starter in the opening hand likely (Inferred)
- Eight hand traps plus Harpie's Feather Duster give layered interaction on the opponent's turn (Inferred)
- Several Level 7 to 10 bosses reach 2800 to 3000 ATK (Verified)
Weaknesses
- Illegal: four Forbidden cards and three over-limit cards (Verified)
- Low archetype purity: 7.7% exact-name copies and 60 off-archetype copies (Verified)
- No Side Deck, so zero post-side adaptability (Verified)
Critical choke points
- Atlantean or Mermail searcher and Level 7 boss route depends on a single WATER-monster Graveyard cost, which is fragile against hand traps (Inferred)
- Forbidden floodgates (Barrier Statue, Gozen Match) are the main non-engine lock and are illegal, leaving the lock plan unavailable (Verified)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Barrier Statue of the Torrent, Called by the Grave, Triple Tactics Talent, Gozen Match | Legal engine or hand-trap slots from the Atlantean or Mermail core (for example a third Mermail Abysspike or a legal Abyss- Spell) | Four Forbidden cards make the list illegal; this is required before any normal score applies |
| 2 | One copy each of Ash Blossom & Joyous Spring, Dominus Impulse and one Droll & Lock Bird | Legal copies: Ash Blossom and Dominus Impulse at 2, Droll & Lock Bird at 1 | Clears the over-limit violations on Semi-Limited and Limited cards |
| 3 | Scattered single-copy off-archetype cards (for example Gluttonous Reptolphin Greethys, Ravenous Crocodragon Archethys) | Additional copies of the core Atlantean or Mermail searchers | Raises archetype purity and brick-free searcher density |
| 4 | A 10 to 15 card Side Deck | Zero Side Deck cards leaves best-of-3 adaptation unscored |
Evidence & confidence
- Verified: Illegal status: four Forbidden cards and three over-limit copy violations; Main 52, Extra 13, Side 0 within size rules; Exact-name archetype purity 7.7%; Zero Side Deck cards
- Inferred: Searcher start probability about 0.81 in a 5-card hand; Hand-trap probability about 0.65 in a 6-card going-second hand; Engine conflict and brick risk from mixed sub-archetypes; Interaction breadth from card text
- Provisional: Meta Power is null: no dated metagame sample; Matchup and format fit: no tournament link
- Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no archetype usage statistics: core and meta-standard comparison unavailable no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry: going-first, going-second and matchup rates are unknown Meta Power is Provisional without a dated metagame sample Deck title is null
