Legality
Main 43 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Extra Deck WATER boss monsters (Poseidra Abyss, Graydle Dragon, Icejade Gymir Aegirine, Azure Ocean Dragon Lord, Abysstrite) reached through the Atlantean/Mermail search-and-summon engine; Umi-field Link and Synchro lines (Worldsea Dragon Zealantis, Levia-Dragoon, Levia-Dragon - Daedalus) enabled by Atlantis, City of the Sea Dragon
- Turn 1 (going first): Open a searcher such as Neptabyss, Mermail Abysspike or Mermail Abyssteus, search the next Atlantean or Mermail piece, and reach a Level 7 Xyz or Synchro boss; this is text-only inference because no recorded boards exist
- Turn 2 (going second): Use Ash Blossom, Dominus Impulse or Mulcharmy draw effects to slow the opponent's first board, then rebuild through searchers; the six-card hand has about a 37 percent chance of containing a hand trap
- Recovery: Recover through searchers and graveyard effects (Mermail Abysspike, Atlantean Heavy Infantry, Warchief of Atlantis) to rebuild the Extra Deck boss
- After siding: None. The deck has no Side Deck, so there is no post-side plan.
Why it scores here
The deck is Illegal in OCG: Ash Blossom & Joyous Spring and Dominus Impulse are each run three times against a Semi-Limited limit of two, so the score is capped and labelled structural-only. The engine is searcher-dense (20 searcher-text cards, about 96 percent to have at least one in a five-card hand per the proxy) and its Extra Deck offers several 2800 to 3000 ATK bosses, which earns the consistency and closing scores. Interaction is layered across hand traps and negation text, but the deck has no Side Deck and no recorded boards, so the combo median, post-side and matchup dimensions stay low or provisional. Popularity was not used as a score input: the Umi archetype has 0 percent exact-name purity and the deck's 58 off-archetype copies were scored as a system, not averaged from card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | Searcher-text cards (20) give about 0.96 P(at least one in hand of 5) and the archetype core group about 0.88 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | Core-group proxy brick rate about 0.12; First Penguin and Mulcharmy board-empty conditions conflict with an Atlantean board (Inferred) |
| D3 | Combo Conversion & Ceiling | 62 | No recorded boards; best line is a text-only read of Atlantis plus Umi Link/Xyz boss routes (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No combo median is available; floor is unknown and kept near the midpoint (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 66 | Three hand traps, Ash Blossom and Dominus Impulse, plus multiple searchers give independent recovery lines (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 62 | Mulcharmy draw effects and searcher density support grind; the off-archetype mix dilutes card economy (Inferred) |
| D7 | End-Board & Interaction Quality | 68 | Eleven removal and nine negation text hits, with Mermail Abyssgaios negation and Daedalus Maelstrom (Inferred from card text) |
| D8 | Going-Second & Board-Breaking Power | 60 | Going-second hand-trap coverage is about 0.37 for at least one hand trap in six cards; no board-breaker count is verified (Inferred) |
| D9 | Offensive Pressure & Closing Power | 72 | Multiple Level 7 or higher bosses at 2500 to 3000 ATK (Verified stats) |
| D10 | Main Deck Efficiency & Flexibility | 58 | Main Deck is legal at 43 cards, but 58 off-archetype copies and nine three-of slots reduce coherence (Verified composition, Inferred efficiency) |
| D11 | Extra Deck Efficiency & Coverage | 65 | Extra Deck is full at 15 with 14 distinct cards spread across Xyz, Synchro and Link summons (Verified) |
| D12 | Side Deck Adaptability | 10 | Side Deck is empty (0 cards), so there is no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link or dated metagame sample exists; Meta Power is null (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step Umi and Atlantean lines with many decision points and an illegal list that must be fixed first (Inferred) |
How the score was computed
Strategy profile: Combo profile primary; Midrange not blended into the weights (structural only). Structural ≈ 61, Going First ≈ 62, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: No reliable metagame: 0.80*Structural(60.6) + 0.20*TournamentReliability(50) = 58.5; modifiers -12 gives 46.5; Illegal-status cap applied gives 35 (theoretical/structural only)
