Phantom Beast (Chimera) Deck #773174 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Fusion Summon boss monsters (Guardian Chimera, Chimera the Flying Mythical Beast, Magnum the Reliever, Berfomet line) through Chimera Fusion and Gazelle / Nightmare Apprentice / Cornfield Coatl searches that feed Illusion and Beast Fusion materials; Extra-Deck link and xyz pressure (Silhouhatte Rabbit, I:P Masquerena, Accesscode Talker, Heretical Phobos Covos, Super Starslayer TY-PHON) once the board is stabilised
• Turn 1 (going first): Opening starters Gazelle, Nightmare Apprentice, Mulcharmy Fuwalos or Chimera Fusion to search Chimera Fusion and Illusion or Beast materials, then Fusion Summon a boss while holding Ash Blossom and Infinite Impermanence for the opponent's response
• Turn 2 (going second): Hold a six-card hand with hand traps (Ash Blossom, Nibiru, Evenly Matched, Infinite Impermanence, Mirror Swordknight, Cornfield Coatl) to answer the opponent's first summon or activation, then convert through Fusion boss plays
• Recovery: Re-searching Chimera Fusion and Gazelle from the Deck, recursion of Berfomet and Gazelle through the GY, and Extra-Deck link and xyz follow-ups after a hand-trap interruption
• After siding: No side deck is present, so no post-side plan can be evaluated

Why it scores here

The deck is Illegal as submitted (two cards run 3 copies where OCG Semi-Limited allows 2), so the score is capped at 38 and the result is structural-only. Its system reads as a Midrange Chimera build: the Chimera Fusion, Gazelle, Nightmare Apprentice and Cornfield Coatl searchers make the archetype core likely to appear in the opening hand (P at least one core card in a 5-card hand about 0.92, Inferred), and the 12 hand traps plus 15 negation-text cards give high interaction density on the system. Ceiling is credited for the Fusion boss package (Guardian Chimera at 3300 ATK, Chimera the Flying Mythical Beast), while the median output and recovery score lower because there are no recorded boards to measure. The score is not a popularity bonus: the archetype usage data confirms the list is real and accessible, but it adds no points by itself, and the score is not an average of individual card scores. The empty side deck and the 70 off-archetype copies (Mulcharmy, Eyes Restrict, Millennium, Polymerization and others) lower the final number.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 60, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: banlist exposure (-8); no side deck (-2); engine conflicts (-2). Final formula: 0.80*Structural(60) + 0.20*TournamentReliability(57) + modifiers(-12) = 47 pre-cap; capped to 38 because legality is Illegal. Meta Power is provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense engine searchers (Gazelle, Nightmare Apprentice, Cornfield Coatl, Chimera Fusion) with a high chance of a core card in the opening hand
• Layered interaction: 12 hand traps, 15 negation-text cards and 21 removal-text cards
• Strong Extra-Deck boss package with Fusion, Link and Xyz options

Weaknesses

• Illegal as submitted: 3 copies of two Semi-Limited cards
• No side deck, so no post-side plan
• 70 off-archetype copies make engine coherence unclear

Critical choke points

• Chimera Fusion is needed for most Fusion Summon routes; losing it to a hand trap or Nibiru-type disruption cuts the main line
• Going second depends on hand-trap density in a 6-card hand (about 0.79)

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom & Joyous Spring and Super Polymerization run 3 copies against OCG Semi-Limited 2; Main 55 and Extra 15 are within size rules; side is empty; Card text and banlist status for all listed cards; Composition counts: 12 hand traps, 19 tech, 17 searcher-text, 15 negation-text, 21 removal-text; Archetype purity: 0% exact name, 70 off-archetype copies
• Inferred: P(at least one core card in opening hand) about 0.92 and searcher-group 0.86; Hand-trap coverage on going second about 0.79; Interaction density and boss-power read from card text; Going-first and going-second power components
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit (D13 held neutral)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: meta-share and per-pilot match record absent No win-rate telemetry exists for this deck Side deck is empty, so D12 has no evidence usage_statistics contradicts the card list: missing_core reports Chimera the Illusion Beast, Chimera the King of Phantom Beasts, Guardian Chimera, Berfomet the Mythical King and Chaos Angel as absent (in_this_deck false), but all five appear in the extra zone with 1 copy each in the cards array; the core coverage figure of 7 of 12 (58.3%) is likely wrong and was not used for scoring The only guide snippet covers a Branded-based Phantom Beast Illusionist build and is off-target for this list Deck title is null and the resolution source is not given in the evidence
