Mythical Beast Deck #769825 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Endymion Spell Counter engine: Spell Power Mastery / Spell Power Attainment search and place counters, Endymion and Magister/Servant of Endymion Pendulum-summon boards, then Link/Pendulum beaters such as Selene and Exceed the Pendulum for closing damage.; Mythical Beast Pendulum beatdown (Master Cerberus, Jackal King, Garuda) with Jackal/Jackal King Pendulum-zone recursion for board pressure.
• Turn 1 (going first): Turn 1: search or draw into a Spell Counter enabler (Spell Power Mastery or Mythical Institution), set Magical Citadel of Endymion, and build counters through Spell activations to power Endymion or Magister.
• Turn 2 (going second): Use Ultimate Slayer, Cosmic Cyclone, Soul Release or Dark Ruler No More to strip one key board piece, then rebuild through Pendulum Summons.
• Recovery: Recover from the GY through Spell Power Mastery/Attainment (GY counterparts) and Jackal recursion; Magia Magic can re-summon Endymion-typed monsters when counters are available.
• After siding: Not evaluable: the deck has zero Side Deck cards, so no post-side plan exists in the export.

Why it scores here

The deck is Illegal: it runs one Forbidden card (Triple Tactics Talent) and three copies of a Limited card (Chicken Game), so under the rubric it receives only a structural cap and no normal Final Contextual score. Structurally, its Endymion Spell Counter engine is searcher-dense (20 searcher-text cards, about 90% chance of at least one in a 5-card opening hand per the hypergeometric estimate) and the archetype core is well represented (about 87% chance of at least one core card in hand). Combo conversion, floor and median output, and going-second board-breaking cannot be measured because the export has no parseable boards, so those dimensions sit near neutral and are Inferred from card text. Interaction is strong on paper (about 30 removal-text and 11 negation-text cards) but there are no hand traps and no side deck, which limits resilience and post-side adaptation. Popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 47, Going First ≈ 45, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-8); no_side_deck (0); illegal_cap (0). Final formula: Illegal deck: structural-only cap. Unconstrained no-meta formula 0.80*47 + 0.20*35 = 44.6, plus banlist modifier -8 = 36.6, then capped to 20 because the deck is Illegal (Triple Tactics Talent Forbidden; Chicken Game over copy limit). Meta Power provisional/null.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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

• Searcher density (20 cards) gives a high chance of finding an engine piece
• Multiple removal and negation options across Spell, Trap and monster effects
• Strong ATK on Endymion, Cerberus and Link beaters for closing

Weaknesses

• Illegal list: Forbidden and over-limit cards must be removed before this can be rated normally
• No side deck, so no post-side adaptation
• No hand traps and no floodgates against going-second boards
• Spell Counter engine needs many Spell activations and complex bookkeeping

Critical choke points

• Spell Counter placement through Spell Power Mastery/Attainment (single engine cluster)
• Pendulum zone occupancy for Jackal/Garuda effects
• Link summon chains depending on Endymion-type monsters on the field

Evidence & confidence

• Verified: Illegal status from copy-limit and Forbidden checks (Triple Tactics Talent Forbidden, Chicken Game 3 copies vs 1); Main 56 and Extra 15 within OCG size rules; Side 0; Card stats and text for all listed cards; Composition counts: 20 searcher-text, 11 negation-text, 30 removal-text, 8 tech, 0 hand traps
• Observed: Usage statistics: 8 of 25 core cards present (32%)
• Inferred: Structural scores D1-D14 and their weights from text and hypergeometric estimates; Going-first and going-second power estimates; Brick and engine reliability reads
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is provisional unless a dated metagame sample is supplied No side deck in the export
