Deck — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (Confidence: Low)
- Primary strategy: Midrange
- Secondary strategies: Control, Toolbox
- Format: ocg
Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Atlantean/Atlantis/Umi board built from Neptabyss, Warchief, Poseidra and Levia-Dragon searches, closed by Poseidra and Link-based boards; Mulcharmy draw-and-discard chip damage and Daedalus removal (Levia-Dragon - Daedalus, Daedalus Maelstrom)
- Turn 1 (going first): Search-driven T1 starter (Neptabyss, Warchief, Mermail Abysspike) into Atlantis or Umi, backed by Ash Blossom and Dimensional Barrier
- Turn 2 (going second): Hand-trap stack (Ash Blossom, Droll and Lock Bird, Maxx C, Ghost Belle, Infinite Impermanence, Nibiru) to stop the opponent's first summon, then rebuild through searchers
- Recovery: Mulcharmy Fuwalos and Purulia draw on opponent summons; Atlantean searchers and Warchief GY revival rebuild the board
- After siding: Not evaluable: the deck has no Side Deck in the export
Why it scores here
This list is Illegal in OCG because it runs one copy each of Bahamut Shark and Triple Tactics Talent, both Forbidden, so the score is capped low and reflects structural potential only. Structurally the deck has a dense searcher network (17 searcher-text cards, 3 Neptabyss, 3 Warchief) that makes an Atlantean/Umi board likely to become live by turn 2 (P(at least one of the archetype core in the opening 5) is about 0.94, Inferred). Interaction is its strongest trait: 13 hand traps and 15 negation/removal texts give it a real answer to opposing starters, especially when going second (P(at least one hand trap in the opening 6) is about 0.82, Inferred). Weaknesses are a conflicting engine (six Mulcharmy cards want an empty field while the Atlantis and Umi cards want a full one), 15 Level-0 Spell/Trap slots that add no board, and no Side Deck. No combos, guides, tournament link or win-rate data exist, so combo conversion and matchup fit are text inference or Provisional, and the score did not come from popularity or from averaging card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one starter in opening 5) about 0.94 for the archetype core; many searchers but a Mulcharmy/Atlantis conflict (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 13 hand traps and 14 tech cards plus 15 non-level spell/trap slots raise brick risk without a full engine (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No parseable combo boards; ceiling is a text-only read of Umi/Atlantis lines (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded boards, so median output is unknown and set conservatively (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 50 | Recursion via Warchief and Mulcharmy plus two Daedalus Link routes give some redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | 17 searcher-text cards and Mulcharmy draw chip support card economy (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | 13 hand traps and 15 negation/removal texts, with Dimensional Barrier and Daedalus Maelstrom (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 65 | Hand-trap density is strongest on the going-second hand (P about 0.82, Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Poseidra 2800 and Levia-Dragoon 2600 Link threats; no end-board data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 55 Main cards with 21 singletons and 6 Mulcharmy triplets; Level-0 Spell/Trap slots dilute the engine (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 58 | 15 Extra cards with Link and Xyz bridges; Bahamut Shark is Forbidden and counts against this (Verified legality) |
| D12 | Side Deck Adaptability | 15 | No Side Deck in the export, so post-side adaptability cannot be scored (Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated metagame or tournament link; archetype share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step Umi/Atlantis/Daedalus interactions with several conflicting conditions (Inferred) |
