Phantom Beast (Chimera) Deck #758278 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Memento Extra Deck pressure: Mementoal Tecuhtlica - Combined Creation (5000 ATK, Special Summoned by shuffling 5 differently named Memento monsters) and Mementomictlan Tecuhtlica - Creation King fusions; Link and Fusion beatdown (Guardian Chimera, Mementotlan Twin Dragon, Mementotlan-Horned Dragon, Super Starslayer TY-PHON) once the board is stable
• Turn 1 (going first): Open a Memento starter (Angwitch, Dark Blade, Tatsunootoshigo, Shleepy, Ghattic) and extend into Fusion or Mementomictlan search; hold Ash Blossom and Ghost Belle for the first opposing Quick Effect
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Droll & Lock Bird, Infinite Impermanence) on the opponent's starter, then rebuild from the Memento graveyard recursion
• Recovery: Recover from the GY through Mementotlan Ghattic, Bone Party, Akihiron and Mementomictlan search; Memento GY count gates Horned Dragon and Combined Creation
• After siding: Not evaluable: the deck runs no side deck (side_count 0), so there is no post-side plan

Why it scores here

The score is built from the deck as a system, not from its card powers. The Memento core (24 Memento-coded cards, 8 in the core group) gives an opening-hand chance of at least one core card of about 0.56 in five cards, and many Memento monsters can start the engine from hand. Interaction is dense (3 Ash Blossom, 3 Ghost Belle, 3 Infinite Impermanence, 3 Forbidden Droplet, Droll and Metaltronus), which lifts D7 and the resilience dimensions. The ceiling comes from Combined Creation and the Creation King fusions, but no recorded boards exist, so median output (D4) stays moderate and is Inferred. The deck is not average-based and popularity earned no points: the archetype label says Chimera, yet only 25% of the usage-core is present and the list is 70 off-archetype copies from the Memento family. The structural result is about 57, with a contextual figure of about 42 after banlist exposure. Because the list is Illegal (two Forbidden cards and three over-limit cards), the final score is capped at 30 and labelled theoretical and structural-only.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with a Stun secondary, disclosed but not blended numerically. Structural ≈ 57, Going First ≈ 56, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural(56.5) + 0.20*TournamentReliability(45) = 54.2; banlist exposure modifier -12 gives 42; capped at 30 because the list is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.56 · 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

• Dense interaction: hand traps and negation text across roughly 17 cards
• Memento recursion and multiple self-summoning starters give redundant routes
• Extra Deck covers Fusion, Link and Xyz with high-impact boss monsters

Weaknesses

• Illegal list: two Forbidden cards and three over-limit cards
• Archetype label (Chimera) does not match the Memento-dominated build; the Chimera core is absent
• Zero side deck, so no post-side adaptability
• Heavy tech and Level-0 spell density lowers consistency

Critical choke points

• Five differently named Memento monsters are needed for Combined Creation
• Guardian Chimera (1 copy) is the only Chimera-core boss in the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 against OCG size rules (40-60 / 0-15 / 0-15); Copy-limit violations: Ash 3/2, Droll 2/1, Called by the Grave 1/0, Triple Tactics Talent 1/0; Archetype composition: 24 Memento, 70 off-archetype copies, 0% exact-name purity
• Inferred: Starter access and brick estimates from hypergeometric draws; Interaction density from text flags and descriptions; Structural dimension scores D1-D14
• Provisional: Meta Power (null); D13 matchup and format fit; Tournament reliability
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry exists in YGOVN for this deck Meta Power is Provisional unless a dated metagame sample is supplied Usage statistics conflict: Guardian Chimera appears in the cards list at 1 copy but is flagged in_this_deck false in the core_cards usage data Archetype label (Phantom Beast Chimera) does not match the Memento-dominated list, so usage-based core comparison is weak
