Chimera Deck #674537 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 42/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Fusion-focused, Midrange
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion-summoned boss monsters with removal and resource generation; Beatdown via high-ATK Fusion monsters
• Turn 1 (going first): Bootstrap into Fusion Summons (Guardian Chimera, Berfomet variants) via searchable Fusion spells and hand discard; generate card advantage and establish interactive board
• Turn 2 (going second): Limited — no dedicated going-second combos recorded; reliant on hand traps and disruption via called negation effects
• Recovery: Graveyard recursion via Chimera Fusion GY activation and monster-sent effects; limited redundancy due to missing core Extra-Deck fusion monsters
• After siding: Unknown — no side deck present; theoretical adaptability hindered by 0 side slots

Why it scores here

The deck's fundamental strength lies in consistent access to Chimera Fusion and searchable starters (Gazelle, Cornfield Coatl, Mirror Swordknight, Nightmare Apprentice), yielding a median combo power of 89 and a reachable ceiling of 100. However, critical structural weaknesses severely limit overall viability: the deck is **illegal** (running 3 copies of Semi-Limited Super Polymerization), runs only 2 combos with going-first orientation and zero recorded going-second lines, missing 56% of the archetype's expected core Extra-Deck monsters (Chimera the Illusion Beast, Predaplant Dragostapelia, Berfomet King, Evolzar Lars) which creates redundancy gaps in both combo lines and interaction. The median board outputs only ~2 negations on 2 bosses with modest defensive statlines, interaction density averages 2.67 per board, and the deck has no side deck (Master Duel allows 15), making post-side adaptation impossible. Popularity or archetype prevalence did not factor into this score—it reflects the deck's system performance: opener reliability is good (98% chance at ≥1 starter T1), but turn-one interaction is fragile (limited to few negations with no backup routes), going-second power is negligible, and recovery after disruption is constrained. Score reflects legality violation and structural underperformance, not a judgment of card quality.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54, Going First ≈ 62, Going Second ≈ 28, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Legality Violation (-10); Missing Core Extra-Deck Coverage (-6); Zero Going-Second Viability (-4); No Side Deck (-3). Final formula: Illegal deck: capped 50 base. Then 0.80·54 (Structural) + 0.20·38 (TournamentReliability) − 10 (legality violation) = 42. Meta provisional (no dated sample).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0 (all Inferred)
• Combo output: best PowerIndex 100, median 89, board-per-starter 1.3
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Consistent T1 opener (98% chance ≥1 starter in opening 5 cards)
• High combo ceiling (best line PowerIndex 100 with strong resource generation and 2-negate board potential)
• Searchable Fusion spell package (Chimera Fusion, Frightfur Patchwork, multiple searcher effects) reduces reliance on hand Polymerization
• Graveyard recursion via Chimera Fusion GY effect and monster-sent GY synergy extends turn length
• Median combo output (PowerIndex 89) is reliable and consistent across 3 recorded examples

Weaknesses

• **Illegal in Master Duel:** running 3 copies of Semi-Limited Super Polymerization (legal max 2)
• Missing 56% of archetype's core Extra-Deck fusion monsters (Chimera Illusion Beast, Predaplant Dragostapelia, Berfomet King, Evolzar Lars) severely limits combo line independence and redundancy
• Zero recorded going-second combos; minimal hand-trap density (4 copies, ~10%) makes turn-2 play almost entirely reliant on post-side tech
• T1 interaction is limited: median 2 negations on modest-statline bosses with no protection mechanics; vulnerable to common disruptions
• No side deck (0/15 filled); cannot adapt to matchups in best-of-3 format
• Single-point-of-failure lines: Fusion Summon access is the primary path; interruption on Fusion spell or searcher often ends the turn
• Offensive closing is slow beatdown; no OTK, piercing, or lethal acceleration mechanics

Critical choke points

• Fusion Summon access: deck revolves around resolving Chimera Fusion or Polymerization; Ash Blossom or similar negation on these spells disrupts most lines
• Super Polymerization illegality: reduces deck's flexibility and forces use of narrow card availability
• Missing core Extra-Deck monsters: blocks independent combo routes and forces reliance on the 2–3 Fusion bosses in-deck
• Graveyard-reliant recursion: banish effects (e.g., Called by the Grave, certain opponent interactions) severely hamper mid-turn recovery
• Turn-2 vulnerability: zero going-second strategy and low hand-trap density mean if the T1 player establishes a board, turn 2 is nearly unwinnable without heavy side-deck tech

Evidence & confidence

• Verified: Legality status: Illegal (Super Polymerization over copy limit); Main Deck size: 40 (legal); Extra Deck size: 15 (legal); Side Deck size: 0 (legal but unused); Card text excerpts from all 27 distinct cards; Copy counts and banlist status per card; Combo evidence: 3 scored combos with PowerIndex, board state, and resource metrics
• Observed: Median combo PowerIndex 89 with consistency across examples; Best combo line (Gazelle + Patchwork) yields 100 PowerIndex, 4 end-monsters, 2 bosses, +5 advantage; Floor combo (Mirror Knight basic) yields 59 PowerIndex, 2 monsters, 1 boss, +3 advantage; Interaction density 2.67 per board; 0.67 negations per board average; Graveyard resource signature: avg 7.33 cards in GY, 3 in end hand, 0.33 banished; Archetype core inclusion: 11 of 25 expected cards present (44%)
• Inferred: Opening-hand consistency: P(≥1 starter T1) ≈ 0.998 from 27 core playable copies (hypergeometric); Brick rate estimate: ~0.2% (near negligible); Going-first board quality ceiling: 2 negations on 3300/3300 + 2400/600 Fusion bosses = moderate interaction, fragile vs. common interruptions; Going-second viability: extremely limited due to zero recorded going-second combos and only 4 hand-trap copies; estimated 28 overall; Redundancy routes post-disruption: only 2 distinct combos recorded; single-choke-point dependency on Fusion Summon access; Piloting complexity: moderate (3–4 step combos, Fusion sequencing, GY state tracking); Post-side potential: unknown without side deck; theoretical matchup adaptability is zero due to 0 side slots filled; Matchup variance: high, due to lack of going-second plan and missing core Extra-Deck cards blocking alternative lines
• Provisional: Meta Power: null (no dated metagame sample supplied; archetype meta-share in Master Duel unknown); Tournament Reliability: 38 (estimated from consistency + post-side vacuum + T2 weakness; no live tournament data); Matchup fit in format: unknown (archetype popularity/meta-share not supplied)
• Data gaps: No tournament context: archetype meta-share, per-pilot match record, and format win-rate telemetry absent No going-second combo evidence: zero recorded T2 lines limits turn-2 evaluation to hand-trap density and speculative board-breaker access (Inferred) No side-deck content: deck has 0/15 side slots filled; post-side matchup adaptation cannot be evaluated (Verified gap) No dated metagame sample: Meta Power cannot be calculated; format speed, common interactions, and meta positioning remain Provisional No detailed piloting guides: strategist decision points and error-recovery patterns inferred from card text and combo examples only Combo line incompleteness: only 3 combos documented; full line diversity and go-wide redundancy unknown
