Deck — Deck Power Evaluation
Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

|---|---|
| Structural Deck Power | 61.2 |
| Going First | 66 |
| Going Second | 62 |
| Meta Power | provisional |
| Tournament Reliability | 55 |

Legality
Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).
Identity & game plan
- Win condition: Extra-Deck boss plays (Poseidra, Icejade Gymir, Adamancipator Risen - Dragite, Poseidra Abyss) after hand-trap and Mermail/Atlantean searches; Mulcharmy draw-engine attrition from a near-empty board
- Turn 1 (going first): Open Mermail Abyssteus / Abysspike / Atlantean searchers to set up Neptabyss or Abyssrhine lines and reach a Level 7 or 8 boss; keep Ash Blossom and Droll for the first hand-trap window
- Turn 2 (going second): Hold Ash Blossom, Evenly Matched, Dominus Impulse and Gameciel to break the opponent's first summon chain, then convert with Poseidra, Coelacanth or Gymir
- Recovery: Mulcharmy Fuwalos/Purulia draw plus GY-cost revival (Abyssteus, Dragoons, Greethys) rebuild a board from a hand of 1-2 cards
- After siding: Not evaluable: the list has no Side Deck, so no post-side plan exists
Why it scores here
This 59-card list is Illegal: five cards exceed their TCG copy limit (Forbidden Called by the Grave and Trishula, plus Semi-Limited and Limited overages), so it receives only a structural, theoretical score capped at 40. Structurally the deck reliably opens a Mermail or Atlantean starter (about 92% for at least one archetype-core card in a 5-card opening, Inferred) and has enough hand traps and searchers to interrupt and rebuild, which earns the resilience and interaction dimensions. Conversion and floor are scored from text alone because no recorded boards exist, so the ceiling (Level 7-8 bosses at 2800-3000 ATK) is not treated as the typical output. Popularity of the Mermail archetype and the 15-card hand-trap suite were not credited as power; the score comes from the deck's system of engine, interaction and boss conversion, not from averaging card scores. The deck has no Side Deck, which costs it heavily on best-of-3 adaptability, and high Mermail/Atlantean purity is absent (about 9.5% exact-name), so the engine is spread over sub-archetypes.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(>=1 archetype-core card in 5-card hand) ≈ 0.92; searcher text ≈ 0.78 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 58 | 15 hand traps, 16 tech and 27 distinct main-deck cards create conflicting openers; Moulinglacia needs 5 WATER in GY (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | No parseable recorded boards; ceiling read from Poseidra/Gymir/Dragite board text only (Inferred) |
| D4 | Combo Floor & Median Output | 52 | No combo median available; floor set near average from text and starter diversity (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 68 | Four overlapping lines (Mermail, Atlantean, Mulcharmy, Abyss) and 15 hand traps give multiple recovery routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Mulcharmy draw and GY-cost revivals recover card economy; no measured resource data (Inferred) |
| D7 | End-Board & Interaction Quality | 74 | Ash Blossom, Evenly Matched, Dominus Impulse, Droll and Gameciel layer negation and removal (Verified text + Inferred) |
| D8 | Going-Second & Board-Breaking Power | 72 | Hand-trap group reaches 84% for going-second six-card hands; board-breaking from Gameciel and Coelacanth (Inferred) |
| D9 | Offensive Pressure & Closing Power | 70 | Level 7-8 bosses at 2800-3000 ATK plus Icejade, Dragite and Poseidra Abyss end-boards (Verified stats) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 59 main cards with 27 distinct and only 9.5% exact-name Mermail purity dilutes engine coherence (Observed composition) |
| D11 | Extra Deck Efficiency & Coverage | 65 | 15 Extra cards, 14 distinct, with three link, synchro and xyz engines covered by two-copy boss lines (Verified composition) |
| D12 | Side Deck Adaptability | 15 | Side deck is empty; best-of-3 has no post-side plan (Verified: side count 0) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample; archetype share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 60 | Multiple conditional revival and discard triggers and sub-archetype routing demand careful sequencing (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 61.2, Going First ≈ 66, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist_exposure (-12). Final formula: Structural 61.2 → 0.80*61.2 + 0.20*55 = 60.0; banlist modifier -12 → 48; Illegal-deck cap → 40 (theoretical/structural-only, no normal Final). Meta provisional.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.92 · 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
- Archetype-core access is high (about 92% at least one in a 5-card opening, Inferred)
- Layered hand traps and negations (15 hand traps, 12 negation-text cards) cover both turns
- Multiple independent lines (Mermail, Atlantean, Mulcharmy, Abyss) give interruption recovery
Weaknesses
- Illegal list: five copy-limit violations including two Forbidden cards
- No side deck, so no best-of-3 adaptation
- Low purity (9.5% exact-name) and 59 main cards dilute the engine
- No recorded boards, so conversion and floor are text-only
Critical choke points
- Forbidden cards Called by the Grave and Trishula must be removed before any legal score can be assigned
- Moulinglacia and Greethys depend on specific GY or hand counts
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave and Trishula, Dragon of the Ice Barrier | Legal replacements (for example one extra Atlantean or Mermail searcher) | Forbidden cards make the list illegal; a legal list is required for a normal Final score |
| 2 | One copy each of Ash Blossom, Dominus Impulse and one Droll & Lock Bird | Legal filler or a second Mermail/Atlantean searcher | Brings copy counts to their Semi-Limited/Limited caps |
| 3 | Low-impact tech cards | A 10–15 card side deck | Gives best-of-3 post-side adaptability (D12 currently 15) |
Evidence & confidence
- Verified: Legality: five copy-limit violations and two Forbidden cards; Main 59, Extra 15, Side 0 against TCG size rules; Card stats and text as supplied in evidence
- Observed: Exact-name Mermail purity 9.5% and archetype spread from composition
- Inferred: Hypergeometric starter access of about 92%; Structural dimension scores D1–D14; Going-first and going-second power estimates
- Provisional: Matchup fit (D13) and meta position: no dated metagame sample
- Data gaps: No recorded combos: combo ceiling, median and floor are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry; going-first and going-second splits are Inferred Meta Power provisional without a dated metagame sample Title is null, so the deck is identified by archetype and id only
