Identity & game plan

Win condition: Establish a Bystial boss monster (Magnamhut, Lubellion) and attack for game; Red-Eyes Fusion/Black Metal Dragon engine to generate high ATK monsters
Turn 1 (going first): Set hand traps, search core cards (Dragon Ravine, Bystial Magnamhut), aim for a quick Bystial summon
Turn 2 (going second): Negate opponent plays with hand traps, then use draw engines to assemble a boss monster
Recovery: Use Ash Blossom, Maxx "C", and Branded Regained to draw into missing pieces and recycle banished resources
After siding: No side deck; the deck relies on its main‑deck consistency

Why it scores here

The deck opens consistently thanks to a 94% chance of drawing a core starter and a low 6% brick estimate, giving it solid early reliability. Its abundant hand‑trap suite and many negation cards let it survive disruption and keep pressure. However, the lack of recorded combo lines and the fragmented engine (many off‑archetype cards) keep its ceiling low, and the illegal Eclipse Wyvern further drags the overall rating. The evaluation therefore reflects strong consistency and interaction but penalizes the missing combo depth and legality issue.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	85	P(at least one core starter in opening 5) ≈ 0.94 (Inferred)
D2	Opening-Hand Quality & Brick Management	80	Full‑brick proxy probability ≈ 0.06 (Inferred)
D3	Combo Conversion & Ceiling	30	No combo boards recorded; inferred low ceiling due to fragmented engine (Inferred)
D4	Combo Floor & Median Output	40	Median output inferred low from lack of combo data (Inferred)
D5	Interruption Resilience & Route Redundancy	70	8 hand‑traps, 10 negation cards give strong interruption resilience (Inferred)
D6	Resource Economy, Recovery & Grind	60	Draw power from Ash Blossom, Maxx "C", Triple Tactics, Branded Regained (Inferred)
D7	End-Board & Interaction Quality	65	Multiple boss monsters and negation effects provide decent end‑board interaction (Inferred)
D8	Going-Second & Board-Breaking Power	55	Hand‑trap group P(at least one in 6) ≈ 0.76, but few dedicated board‑breakers (Inferred)
D9	Offensive Pressure & Closing Power	55	Presence of Bystial Magnamhut, Lubellion, Red‑Eyes Black Fullmetal as finishers (Inferred)
D10	Main Deck Efficiency & Flexibility	50	31 distinct cards, 48% archetype purity indicates moderate main‑deck efficiency (Inferred)
D11	Extra Deck Efficiency & Coverage	45	15‑card Extra Deck with many non‑core links shows limited coverage (Inferred)
D12	Side Deck Adaptability	30	Side deck empty; no adaptability after side‑in (Inferred)
D13	Matchup Coverage & Format Fit	40	No tournament data; matchup fit provisional (Provisional)
D14	Pilotability & Error Tolerance	40	Complex limited‑card interactions and many steps lower pilotability (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 56, Going First ≈ 60, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal card (Eclipse Wyvern) (-10); No side deck (-5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
Combo output: best PowerIndex —, median —, board-per-starter —
Turn order: 0 going-first lines vs 0 going-second lines

Strengths

Very high chance to open a core starter
Robust hand‑trap and negation suite
Multiple draw engines for resource recovery

Weaknesses

Illegal card (Eclipse Wyvern) blocks legality
Fragmented engine with many off‑archetype cards
No recorded combo lines, low ceiling

Critical choke points

Reliance on limited Bystial Magnamhut
Eclipse Wyvern (forbidden) prevents legal play
Limited side‑deck options

Recommended changes

Priority	Remove	Add	Reason
1	Eclipse Wyvern	Legal Bystial core monster (e.g., Bystial Druid)	Eliminate illegal card and improve engine cohesion
2	Some off‑archetype generic cards	More Bystial or Rokket synergy cards	Increase archetype purity and reduce variance

Evidence & confidence

Verified: legality status; card text excerpts; copy counts
Inferred: core starter probability; brick estimate; hand‑trap density; draw engine presence; boss monster presence; main‑deck and extra‑deck composition analysis; pilotability assessment
Provisional: matchup format 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
