Metaphys Deck #50764 — Yu-Gi-Oh! Master Duel

Metaphys (Illegal build) — Deck Power Evaluation

Final Contextual Deck Power: 15/100 (±5 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Combo
• Format: master-duel

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Banish-fueled board development with Metaphys/Chaos monsters and Extra Deck beaters; Resource denial via Necroface and banish loops
• Turn 1 (going first): Use Chaos Space, Metaphys Ragnarok, and spell searchers to special summon and banish for advantage (theoretical)
• Turn 2 (going second): Forbidden Droplet, Twin Twisters, and board-breaking spells to clear opponent field (theoretical)
• Recovery: Banish recovery via Metaphys Nephthys/Daedalus standby effects and Chaos Creator
• After siding: No side deck present (0 cards); no post-side adaptation possible

Why it scores here

This deck is evaluated as theoretical/structural-only because it is Illegal in Master Duel, containing Forbidden cards (Cyber-Stein, Chaos Ruler, Apollousa) and over-limit Limited/Semi-Limited cards. The system as listed shows a scattered 60-card Metaphys/Chaos/Thunder Dragon toolbox with low archetype purity (10.7%) and missing key core cards like Gren Maju Da Eiza, yielding low consistency (P(core open)≈0.52). No combo records exist, so ceiling/floor are inferred from card text alone and cannot be realized legally. The score was capped low per rubric, not from averaging card scores or from archetype popularity, and the deck would require major revisions to be legal and coherent.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 33, Going First ≈ 35, Going Second ≈ 35, Meta = provisional, Tournament Reliability ≈ 20. Modifiers: Illegal deck (-20); No side deck (-5). Final formula: Illegal deck: theoretical structural only; Final Contextual capped low per rubric (no normal formula)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.52 · key two-card combo ≈ — · full-brick estimate ≈ 0.48 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Multiple search and draw spells provide card advantage (Inferred)
• Extra deck contains generic link monsters for toolbox plays (Verified)

Weaknesses

• Illegal due to forbidden/over-limit cards (Verified)
• 60-card main deck with low archetype purity reduces consistency (Inferred)
• Missing key Metaphys core cards like Gren Maju, Aloof Lupine (Verified)

Critical choke points

• Reliance on forbidden Extra Deck cards (Apollousa, Chaos Ruler) for negation (Verified)
• No hand traps to disrupt opponent (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality violations (Forbidden/over-limit); Card text for forbidden cards; Usage stats missing core cards; Side deck count 0; Extra deck breakdown
• Inferred: Consistency estimates from hypergeometric P(core)=0.5241; Brick rate proxy 0.4759; Low median output due to sparse engine; Resource economy from spell density
• Provisional: Meta Power (no dated metagame); 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
