Deck — Deck Power Evaluation
Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 60 |
| Going First | 60 |
| Going Second | 55 |
| Meta Power | provisional |
| Tournament Reliability | 50 |
- Primary strategy: Midrange
- Secondary strategies: Stun, Control
- Format: tcg
Legality
Main 54 / Extra 14 / Side 0 — status: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Extra Deck beaters and Kozmo Special Summon pressure (Dark Eclipser, Forerunner, Dark Destroyer, Gaia Dragon, Panzer Dragon) once the board is established; Recursion of Kozmo monsters from the Graveyard and banish-based Special Summons
- Turn 1 (going first): Open a Kozmo monster and Kozmo Tincan or Farmgirl, then use hand-summon effects to reach a Level 7+ Kozmo beater while Call of the Haunted and Solemn cards protect the board; legal-copy results only, as the list is illegal
- Turn 2 (going second): Use Effect Veiler and the Solemn traps to answer the opponent's first summon or effect, then rebuild through Kozmo hand-summons and GY recursion; Dark Hole and Raigeki are the board-wipe backstop
- Recovery: Banish Kozmo monsters from the Graveyard to Special Summon Kozmo monsters from the Deck, and use Kozmotown to shuffle hand Kozmo monsters back for draws
- After siding: No side deck is registered (side_count 0), so no post-side plan can be evaluated
Why it scores here
The deck is scored as a system: a Kozmo hand-summon engine (25 archetype-core copies, about 96% chance of at least one in a 5-card opening hand, Inferred) supported by Solemn and Call of the Haunted interaction, Effect Veiler, and a Level 7+ Extra Deck finish. Structural strength comes from consistent engine access, layered negation and removal, and graveyard recursion, which together carry the midrange profile. The score is held back by a 33-copy Spell/Trap count with 21 Main Deck monsters (brick risk), no recorded boards (floor and median are text-only inferences), and the absence of any side deck. The list is illegal: three Forbidden copies and three Reasoning copies over the Limited cap cap the score at 35 under the rubric, so this is a theoretical, structural-only read. Popularity and archetype usage did not earn points, and card scores were not averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(≥1 archetype-core card in a 5-card opening hand) ≈ 0.96; Kozmo hand-summon starters are numerous (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 60 | Spell/Trap count 33 of 54 Main Deck cards and only 21 monsters imply a moderate brick risk; no measured brick rate (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | Ceiling comes from Dark Eclipser, Forerunner, Dark Destroyer and Gaia Dragon, but no recorded boards exist to confirm it (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No combos_evidence rows, so the median is unmeasured and set below the ceiling as a conservative estimate (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 65 | Graveyard Kozmo recursion and multiple negation routes (Solemn Strike, Solemn Warning, Effect Veiler, Breakthrough Skill) give alternatives after disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Kozmotown and Tincan/Farmgirl searches plus GY recursion regenerate resources, offset by 500 LP and 1000 LP costs (Inferred) |
| D7 | End-Board & Interaction Quality | 75 | Solemn Strike, Solemn Warning, Effect Veiler, Mask of Restrict, Call of the Haunted and Dark Hole/Raigeki give layered interaction (Verified card text, Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 60 | Dark Hole and Raigeki are board breakers, and Dark Eclipser is a large going-second threat, but going-second boards are unmeasured (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Level 7+ beaters reach 2600–3000 ATK with direct and piercing text on some Extra Deck monsters; no closing-rate data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 54 Main Deck cards with 33 non-monster slots and 3-copy Kozmo staples are compact but heavy on non-engine cards (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 14 Extra Deck cards cover Xyz, Synchro, and Fusion options, with Abyss Dweller and Trishula illegal and removed from the evaluation (Verified/Inferred) |
| D12 | Side Deck Adaptability | 45 | No side deck is registered, so post-side adaptability cannot be assessed (Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated metagame or tournament link; the Solemn archetype share is unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 55 | Multi-step Kozmo hand-summon chains with banish costs and LP-cost effects raise decision load (Inferred) |
How the score was computed
Strategy profile: Midrange weight profile used as primary; Stun is secondary and was not blended into the weights. Structural ≈ 60, Going First ≈ 60, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-8); Unresolved passcode (-2). Final formula: Uncapped: 0.80*60 + 0.20*50 + modifiers(-10) = 48; Illegal cap applied per rubric Step 2, final 35 (theoretical/structural-only); Meta provisional
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.96 · 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
- Kozmo hand-summon engine gives high starter access
- Layered negation and removal (Solemn Strike, Solemn Warning, Effect Veiler, Call of the Haunted)
- Graveyard recursion of Kozmo monsters gives resilience
Weaknesses
- Illegal copy and banlist violations (Reasoning x3, three Forbidden cards)
- Large non-monster share (33 Spell/Trap) raises brick risk
- No recorded boards, so floor and median are unmeasured
- No side deck
Critical choke points
- Kozmo starter in hand for the turn-1 plan
- Solemn Warning and Solemn Strike LP costs (2000 and 1500)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Trishula, Dragon of the Ice Barrier; Abyss Dweller; Vanity's Emptiness | Legal replacements of the same role (Extra Deck beater or Main Deck interaction) | These are Forbidden in TCG and make the list illegal |
| 2 | 2 of the 3 copies of Reasoning | A legal Main Deck card of the same role | Reasoning is Limited (1 legal copy) and is run 3 times |
| 3 | None | A side deck (up to 15 cards) | Side count is 0, so the deck has no post-side plan |
Evidence & confidence
- Verified: Legality: 4 violations (3 Forbidden or over-limit cards, Reasoning x3 vs limit 1); Main 54 and Extra 14 are within TCG size rules; Card text for Solemn Strike, Solemn Warning, Effect Veiler, Dark Hole and Raigeki
- Inferred: At least one archetype-core card in opening hand ≈ 0.96; Midrange structural score 60 from the weighted dimensions; Engine access and interaction quality from card text
- Provisional: Meta Power (null, no dated metagame sample); Matchup fit (D13 = 50); Side-deck adaptability (no side deck)
- 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 Passcode 10443957 could not be resolved and is counted as Main Deck usage_statistics marks Chimeratech Fortress Dragon, Constellar Pleiades, Number 61: Volcasaurus and Castel as in_this_deck=false, but the cards array lists all four in the Extra Deck; the inconsistency was not resolved No win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered (side_count 0)
