B.E.S. Deck #772577 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Boss monsters (Super B.E.S. Metal Slave, B.E.S. Big Core MK-3, B.E.S. Blaster Cannon Core) backed by Boss Rush recursion (Inferred from card text; no recorded boards); Ohime the Manifested Mikanko beatdown with Mikanko equip recursion, but Ohime is uncastable without Mikanko Kagura, which is not in the list
• Turn 1 (going first): Open a B.E.S. starter (Derringer Core or Zelos) with a searcher, then extend into Metal Slave or Big Core (Inferred)
• Turn 2 (going second): Hold a hand trap (Ash Blossom, Ghost Belle, Infinite Impermanence) to protect the starter, then bring out a boss monster (Inferred)
• Recovery: Boss Rush revives a B.E.S. monster or Big Core from the Deck in the End Phase after one is destroyed; Tetran and Big Core recycle through the Graveyard (Inferred)
• After siding: None: the Side Deck is empty, so there is no post-side plan

Why it scores here

The deck opens a B.E.S. starter in roughly a third of opening hands (P(≥1 Derringer Core in 5 cards) ≈ 0.34) and has a searcher-text card in about 90% of opening hands, so the engine starts often enough to be playable. Its strength is interaction: nine hand traps (Ash Blossom, Ghost Belle, Infinite Impermanence) give about 81% odds of at least one going second, and Boss Rush plus the Big Core line gives it some recovery. Its weaknesses are structural: archetype purity is 35% across two sub-archetypes, three Ohime copies cannot be Ritual Summoned because Mikanko Kagura is absent, and the deck has no Extra Deck and no Side Deck. The score is not an average of card scores and does not reward popularity. It is capped at 30 because the deck runs three Ash Blossom against a limit of two, so it is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary; Stun secondary used only for the interaction read (D7, D8). Structural ≈ 51, Going First ≈ 46, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); engine conflict (-3); unrecoverable_dead_cards (-2); illegal_deck_cap (-9). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 49.8, then context modifiers −11 = 38.8, then illegal-deck cap to 30 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Nine hand traps give about 81% odds of at least one going second
• Boss monsters (Metal Slave 3100 ATK, Big Core MK-3 2700 ATK) provide closing bodies
• Searcher density (14 searcher-text cards) gives about 90% odds of a search in the opening hand
• Boss Rush gives recursion after a B.E.S. monster or Big Core is destroyed

Weaknesses

• Illegal: three Ash Blossom against a limit of two
• Three Ohime cannot be Ritual Summoned because Mikanko Kagura is missing
• Only 35% exact-archetype purity; two sub-archetypes split the engine
• No Side Deck and no Extra Deck, so there is no post-side or Extra Deck plan

Critical choke points

• Starter access depends on a 3-copy B.E.S. starter with about 34% odds in the opening hand
• The Ash Blossom legality violation has to be fixed before any score can be trusted

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2 (Illegal); Main Deck is 40 cards with Extra 0 and Side 0; Exact-archetype purity is 35% (B.E.S. 14, Mikanko 11, generic 15); Mikanko Kagura is not in the list, so Ohime's Ritual Summon is unavailable
• Inferred: Starter and searcher odds from the hypergeometric table; Hand-trap coverage going second; Boss Rush and Big Core recursion as recovery; Interaction density from card text
• Provisional: Meta Power and D13 matchup fit, since there is no dated metagame sample or tournament link
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference usage statistics core list does not match this deck's archetype (its 25 core cards are R.B., Sky Striker, Clockwork and similar, and only 2 are present); treat the usage read as unreliable and do not use it to judge deviation from standard No tournament link: archetype meta-share and per-pilot match record are absent No Side Deck, so post-side performance cannot be assessed Deck title is null No win-rate telemetry exists in YGOVN
