Legality
Main 53 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Kozmo monster beatdown (Dark Destroyer, Dark Eclipser, Forerunner at 2800-3000 ATK) and Xyz/Synchro boss monsters; Kozmo recursion from the Graveyard and Extra Deck Xyz boards (Cyber Dragon Nova, Gaia Dragon not in list)
- Turn 1 (going first): Open a Kozmo starter (Tincan, Farmgirl, Sliprider, Strawman) and chain banish-from-hand Special Summons into a level-7+ Kozmo, then protect with Solemn Strike/Warning and Kozmojo
- Turn 2 (going second): Force interaction with Dark Hole, Raigeki, Solemn Strike or Solemn Warning, then rebuild through Kozmo GY recursion and Xyz plays
- Recovery: Kozmo monsters banished from the Graveyard re-Special Summon lower-level Kozmo; Kozmotown recycles banished Kozmo for draws
- After siding: Not assessable: the deck has zero Side Deck cards, so there is no post-side plan
Why it scores here
The deck is Illegal in the TCG format: Reasoning is run three times against a Limited limit of one, and Vanity's Emptiness and Abyss Dweller are Forbidden, so the score is a theoretical structural read capped low and not a normal contextual score. Structurally the list reliably opens a Kozmo starter (about 0.97 chance of at least one archetype-core card in the opening hand, Inferred), and its Kozmo recursion from the Graveyard and banish-from-hand Special Summons give it real resilience and card-economy lines. Its interaction suite (Solemn Strike, Solemn Warning, Dark Hole, Raigeki, Effect Veiler, Kozmojo) is dense, which lifts the end-board score. The deck has no Side Deck, no recorded combos and no tournament record, so the combo and matchup scores are text-only inference. This score was not produced by averaging card scores or by the popularity of Kozmo (the core appears in 72.7 percent of usage rows, which confirms only that the list is real).
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one archetype-core card in opening 5) = 0.97; 3-copy starters about 0.26 each (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 27 distinct main-deck cards with 12 singletons and 33 level-0 spells/traps; moderate brick and tech density (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No parseable combos; ceiling judged from card text only (Kozmo chain summons, Forerunner, Dark Destroyer) (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No recorded boards, so median output is unmeasured and set low to reflect that (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Graveyard Special Summon recursion across several Kozmo monsters plus multiple negations give alternate routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 58 | Kozmotown and Kozmo Tincan search and recycle banished Kozmo; Kozmo Forerunner gains LP (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | Nine-plus negate, destroy and summon-prevention cards, including Solemn Strike, Solemn Warning and Vanity's Emptiness (Inferred from text; Vanity's is Forbidden) |
| D8 | Going-Second & Board-Breaking Power | 62 | Dark Hole, Raigeki and Solemn traps provide going-second board breaking; no recorded going-second split (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Dark Destroyer and Dark Eclipser at 3000 ATK and Forerunner at 2800 ATK; no end-board data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 53 main cards with heavy 3-copy use and one over-limit Reasoning; compact but not clean (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 50 | Ten Xyz, three Fusion and two Synchro with an Illegal Abyss Dweller; mixed and partly unusable (Verified legality, Inferred function) |
| D12 | Side Deck Adaptability | 15 | Zero Side Deck cards, so no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated meta sample or tournament link; archetype usage only (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Dense chain-and-summon sequencing with many optional effects; decision load is high (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Illegal: theoretical structural-only cap. Uncapped 0.80*55 + 0.20*45 + modifiers(-12) = 41, capped to 20 because the list violates copy limits and runs Forbidden cards
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.97 · 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
- Dense Kozmo core with high opening-hand odds (0.97 for at least one core card)
- Strong interaction suite across traps, Spells and monster effects
- Graveyard recursion gives multiple routes after disruption
Weaknesses
- Illegal list: over-limit Reasoning and two Forbidden cards
- No Side Deck, so no post-side plan
- No recorded combos, so floor and median are unmeasured
Critical choke points
- Kozmo starters: most lines need one of about 15 Kozmo monsters in hand
- Forbidden Vanity's Emptiness and Abyss Dweller must be removed before any legal evaluation applies
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Reasoning (2 of 3 copies) | Legal copy-count fix, or the Forbidden cards removed | Copy limit is the legality blocker |
| 2 | Vanity's Emptiness and Abyss Dweller | Legal Kozmo or Extra Deck replacements | Forbidden in TCG, so the deck cannot be played as built |
| 3 | None (the deck has no side) | A 15-card Side Deck of Kozmo-compatible answers | Side adaptability scores 15 without one |
Evidence & confidence
- Verified: Reasoning run 3 copies against Limited limit 1; Vanity's Emptiness (Forbidden) and Abyss Dweller (Forbidden) present; Main 53 and Extra 15 within size rules; Zero Side Deck cards; Kozmo core appears in 72.7 percent of usage rows
- Inferred: 0.97 at least one Kozmo core card in opening hand; Dense interaction suite (D7 70); Graveyard recursion resilience (D5 60); Structural score 55 on the Midrange profile
- Provisional: Meta power and matchup fit (no dated meta or tournament data)
- Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is provisional without a dated metagame sample Deck title is null Side Deck is empty
