Legality
Main 42 / Extra 3 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Summon Malefic Cyber End Dragon / big beatsticks under Skill Drain lock; Tribute Summon Beast King Barbaros for board wipe
- Turn 1 (going first): Establish field spell + Skill Drain + boss monster
- Turn 2 (going second): Counter traps to disrupt opponent's summon/spell
- Recovery: Trade-In / Pot of Duality draw, Monster Reborn revival
- After siding: None (empty side deck)
Why it scores here
This deck is illegal in the OCG format due to running 3 copies each of Limited cards Terraforming and Skill Drain, so it cannot be played as submitted and receives a capped theoretical evaluation only. The system centers on Malefic Cyber End Dragon backed by field spells and Skill Drain floodgate, but the combo evidence is absent and consistency is inferred from hypergeometric odds around 0.32 for key pieces. Popularity or archetype meta-share earned no points, and the score is not an average of individual card power but a system read of a non-playable list. If made legal, the deck would still suffer from a thin extra deck and no side deck, limiting tournament reliability.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 40 | P(≥1 Mausoleum/field starter in 5) ≈ 0.32; Malefic boss needs field + extra deck banish (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 35 | Copy histogram shows mixed singles/duplicates but dead draws without field spell (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | Malefic Cyber End Dragon 4000 ATK with attack lock; ceiling moderate but no recorded boards (Inferred) |
| D4 | Combo Floor & Median Output | 30 | No combo logs; median output likely a single big monster under Skill Drain (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 25 | Few recursion options; mainly Monster Reborn limited, low route redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 30 | Trade-In and Pot of Duality provide draw but lock special summons; resource grind weak (Inferred) |
| D7 | End-Board & Interaction Quality | 50 | Skill Drain floodgate + 4 counter traps negate monster effects; interaction layered (Verified text) |
| D8 | Going-Second & Board-Breaking Power | 20 | Going-second split unavailable; only 2 copies of board breakers like Forbidden Lance (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | Boss monsters 3000-4000 ATK with piercing on some; closing power via beatdown (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 42-card main with mixed sub-archetypes; inefficient but within size (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 20 | Extra deck only 3 Cyber End Dragon fusions; minimal coverage (Verified) |
| D12 | Side Deck Adaptability | 0 | Side deck empty (0 cards) → no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 30 | No dated metagame sample; format fit provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 50 | Simple tribute/summon lines but illegal build confuses pilot; error tolerance medium (Inferred) |
How the score was computed
Strategy profile: primary only. Structural ≈ 35, Going First ≈ 30, Going Second ≈ 20, Meta = provisional, Tournament Reliability ≈ 15. Modifiers: Illegal copy limit (-30); No side deck (-5). Final formula: Illegal deck: no normal Final Contextual score; capped low per rubric (theoretical structural-only)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.32 · key two-card combo ≈ — · full-brick estimate ≈ 0.68 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- High-impact boss monsters (4000 ATK)
- Skill Drain floodgate shuts off opponent effects
Weaknesses
- Illegal over-limit copies of Terraforming and Skill Drain
- No side deck
- Thin extra deck (only 3 fusions)
- No hand traps
Critical choke points
- Terraforming/Skill Drain over limit makes deck illegal
- Requires face-up Field Spell to keep Malefic Cyber End Dragon on field
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 2 Terraforming | 1 Terraforming (keep legal 1) or replace with generic field search | Reduce to legal 1 copy of Limited card |
| 2 | 2 Skill Drain | 1 Skill Drain (legal) + other staple trap | Limit to 1 copy of Limited card |
Evidence & confidence
- Verified: Legality status Illegal; Card text for Skill Drain, Malefic Cyber End Dragon; Extra deck 3 Cyber End Dragon
- Inferred: Consistency probabilities; Brick risk; Interaction layering
- Provisional: Meta Power; Matchup fit
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
