Exchange of the Spirit Deck #450672 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: none
• Format: master-duel

Legality

Main 44 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Establish a Madolche field and lock opponent with hand traps; Utilize Exchange of the Spirit monsters for removal and extra deck disruption
• Turn 1 (going first): Search for Madolche engine pieces, set up hand traps, and Normal Summon a Madolche monster to start the loop
• Turn 2 (going second): Deploy hand traps on opponent's turn, then use extra‑deck summons to break board and continue engine
• Recovery: Shuffle dead Madolche monsters back into the deck with Madolche Chateau and Dessert, then resummon via searchers
• After siding: No side deck; rely on hand‑trap versatility and engine recursion

Why it scores here

The deck can reliably open a Madolche engine thanks to abundant searchers and hand traps, but the illegal extra copy of Herald of Orange Light prevents legal play and hurts consistency. Engine conversion reaches modest peaks when the loop resolves, yet the lack of recorded combo data shows a low median output. Interaction is decent with several negates, but the absence of a side deck and reliance on specific Madolche pieces create fragile recovery paths. Overall the system is functional but heavily penalized by legality and brick risk, resulting in a low contextual power.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 45, Going First ≈ 40, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal overcopy of Herald of Orange Light (-12); No side deck (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) – illegal copy penalty

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Very high number of searchers (18 copies) ensures consistency in fetching key pieces
• Six hand‑trap cards give solid disruption especially when going second
• Full 15‑slot Extra Deck filled with versatile Madolche Xyz/Link options

Weaknesses

• Illegal overcopy of Herald of Orange Light prevents legal play
• No side deck limits adaptability to matchup tech
• Core engine consistency low; only ~11% chance to have a core starter in opening hand
• No recorded combo data; median output likely weak

Critical choke points

• Herald of Orange Light copy limit violation
• Reliance on specific Madolche loop cards that may be disrupted

Recommended changes

Evidence & confidence

• Verified: Legality status and copy‑limit violation; Card role_hint_tags and text_role_hints; Hypergeometric draw probabilities
• Inferred: Engine accessibility based on core starter probability; Brick risk from copy histogram and type spread; Combo ceiling and floor from card effects and lack of boards; Resilience from hand‑trap and negation counts; Resource economy from Madolche shuffle loops; Interaction quality from hand‑trap and negation density; Going‑second board breaking from hand‑trap group probability; Closing power from monster ATK ranges; Main‑deck efficiency from archetype purity and spread; Extra‑deck efficiency from slot usage; Pilotability from number of conditional effects
• Provisional: Matchup and meta fit due to missing tournament data
• 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
