Ojama Deck #37035 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Tempo
• Format: master-duel

Legality

Main 60 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Large Link and Xyz boards (Gameciel, Jizukiru, Chaos Dragon Levianeer, Gadarla) converting into direct attacks, with the Ojama and ABC pieces as the bridge; Armed Dragon Thunder and Pile Armed Dragon beatdown through the Ojama chain
• Turn 1 (going first): Ojamagic or Ojama Blue search for the Ojama Trio, then Ojamatch or Interrupted Kaiju Slumber to reach a Kaiju or Link board; structural only because the list is illegal
• Turn 2 (going second): Hand-based plays through Ojama Red or Ojama Pink followed by Kaiju Summons in response to a board; not testable without a legal list
• Recovery: Ojama and Orcust searchers (Ojama Blue, Orcustrated Babel, Ojamagic) plus Dingirsu and Galatea recursion from the GY
• After siding: Not evaluable: the deck has no side deck (Side Deck size 0)

Why it scores here

The list is Illegal: four Forbidden copies (Called by the Grave x2, Terraforming, Apollousa, Union Carrier) are in the Master Duel ban field, so this is a structural-only read and the score is capped low. Starter access is reasonable: the searcher-text group has a 0.949 chance of at least one hit in a 5-card opening, though the searchers feed several unrelated engines. The deck is not coherent as one system: exact Ojama name purity is 14.9%, and the Ojama core is mixed with Orcust, Kaiju, Armed Dragon, ABC, Knightmare, and Qli. Floor and median output cannot be assessed because there are no recorded boards, and the side deck is empty, so going-second and post-side plans are not evaluated. The score did not come from averaging card scores or from archetype popularity; no usage or tournament data for this list exists.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 42, Going First ≈ 40, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-10). Final formula: Structural 41.7 x 0.80 + TournamentReliability 35 x 0.20 = 40.4; banlist modifier -10 gives 30.4; Illegal list capped to 25 (structural-only; Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Legal size: 60 Main, 14 Extra, within master-duel bounds
• Searcher density gives high P(>=1) in a 5-card opening
• Strong boss ATK in the Extra Deck (Jizukiru, Gameciel, Chaos Dragon Levianeer)

Weaknesses

• Four Forbidden cards make the list Illegal
• Exact Ojama purity is 14.9%; the engines are fragmented
• Empty side deck: no post-side plan
• No combo, tournament, or guide evidence

Critical choke points

• Ojama Trio access depends on Ojamagic or Ojama Blue search, which is itself a single-copy chain
• Forbidden cards removed would leave Ojamatch and Interrupted Kaiju Slumber as the only Kaiju routes

Recommended changes

Evidence & confidence

• Verified: Four Forbidden copies in master-duel (Called by the Grave x2, Terraforming, Apollousa, Union Carrier); Main 60, Extra 14, Side 0; size rules met; Exact-name Ojama purity 14.9%; Searcher-text P(>=1 in 5) = 0.9491
• Inferred: Starter and engine access estimated from card text and hypergeometric probabilities; Brick and conflict risk from the copy histogram and archetype spread; Ceiling from card text (Gameciel, Jizukiru, Chaos Dragon Levianeer)
• Provisional: Meta and format fit (no dated sample, no tournament link)
• Data gaps: No combos supplied: floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for this deck usage statistics lists Reptilianne core cards (none present), which does not match the Ojama archetype; not used as an Ojama core No guides attached No side deck, so post-side performance cannot be evaluated
