Legality
Main 40 / Extra 15 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Attrition & Battle Phase Removal; Synchro/Xyz Board Control
- Turn 1 (going first): Establish interactive board with Crystron/K9 starts, protect with Cluster, pressure with boss monsters.
- Turn 2 (going second): Use hand traps to disrupt, then leverage Mulcharmy/K9 searchers to rebuild board and break through.
- Recovery: Recycle Crystrons via Inclusion/Cluster, draw via Mulcharmy/Fuwalos to sustain grind.
- After siding: Unable to execute; side deck is empty.
Why it scores here
This deck functions as a resilient Midrange system built around Level 5 Machine engines, leveraging high core consistency (P≥1 starter ≈ 0.98) and a dense hand-trap suite to control the pace. Its strength lies in resource recursion via Crystron Inclusion and Cluster, alongside strong negation coverage, allowing it to convert average openings into interactive boards. However, the complete absence of a side deck severely caps its Best-of-3 viability, and missing key staples like Clockwork Knight and Cyber Dragon Nova dilutes engine cohesion. The score reflects a solid but unpolished system that performs reliably in isolation but struggles with format adaptation and pilot complexity.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 88 | Archetype core group P(≥1 in opening 5) ≈ 0.98; high consistency across Crystron/K9/Mulcharmy (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 78 | 9 hand traps + low brick rate; strong opening stability (Verified) |
| D3 | Combo Conversion & Ceiling | 62 | Text-only inference of ceiling lines; moderate board generation without parsed combos (Inferred) |
| D4 | Combo Floor & Median Output | 65 | Median output relies on Crystron Inclusion/Sulfador loops; stable but unverified (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 72 | Multiple independent starters (Noroi, Izuna, Jokul) + Cluster protection; resilient (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 76 | Recursion via Inclusion/Cluster and draw engines (Fuwalos/Purulia); strong grind potential (Inferred) |
| D7 | End-Board & Interaction Quality | 82 | High negation density (Ash, Impermanence, Droll, Spell Canceller, boss monsters); robust interaction (Verified) |
| D8 | Going-Second & Board-Breaking Power | 68 | Called by the Grave, Spell Canceller, and Cluster provide adequate board-breaking tools (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Solid boss monsters (Lupis, Infinity, Zeus) but lacks piercing/direct damage focus (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 75 | 40-card compact list with 21 distinct cards; efficient slot allocation (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 70 | Full 15-slot Extra Deck with balanced Xyz/Link/Synchro coverage (Verified) |
| D12 | Side Deck Adaptability | 15 | Side deck contains 0 cards; completely unable to adapt post-side (Verified) |
| D13 | Matchup Coverage & Format Fit | 55 | Niche presence in Master Duel; alignment with environment is speculative (Provisional) |
| D14 | Pilotability & Error Tolerance | 52 | Multi-engine complexity increases decision points and error risk (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 70, Going First ≈ 72, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Empty Side Deck (-5); Missing Key Cores (-4); High Hand Trap Density (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- High core consistency (P≥1 starter ≈ 0.98)
- Strong hand trap suite (Ash, Impermanence, Droll, Maxx C)
- Excellent resource recursion via Crystron Inclusion and Cluster
- Flexible Level 5 engine for Xyz/Synchro plays
Weaknesses
- Zero side deck cards cripples post-side adaptation
- Missing critical archetype cores (Clockwork Knight, Nova, Infinity, Eleskeletus)
- Complex multi-engine setup increases pilot error risk
- Lack of parsed combo data forces reliance on text inference
Critical choke points
- Dependence on drawing specific Level 5s for Xyz/Synchro access
- Vulnerability to mass banish despite Cluster protection
- Inability to adjust after Game 2 due to empty side deck
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Scrap Recycler | Clockwork Knight | Restores essential K9 search synergy and reduces non-engine filler. |
| 2 | Spell Canceller | Cyber Dragon Nova | Replaces a situational stopgap with a core engine extender and boss monster. |
| 3 | Mulcharmy Purulia | Foolish Burial | Adds reliable Crystron recursion while maintaining draw potential. |
Evidence & confidence
- Verified: Legality status; Card counts and copy limits; Banlist statuses; Side deck size is 0
- Inferred: Core consistency probability (P≥1 starter ≈ 0.98); Combo floor/median estimates from card text; Post-side vulnerability due to 0-card side deck; Resource economy strength from Inclusion/Cluster/Mulcharmy loops
- Provisional: Matchup format fit; Tournament reliability
- 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
