Ojama Deck #772280 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 44/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck boss monsters from the ABC, Armed Dragon and Knightmare lines (ABC-Dragon Buster, A-to-Z-Dragon Buster Cannon, Armed Dragon Catapult Cannon, Underworld Goddess) reached through search-driven engines; Ojama Trio board-control turns (Ojama Duo, Ojama Delta Hurricane!!) that clear the opponent's field before a link or fusion attack
• Turn 1 (going first): Open with a searcher (Ojamagic, Ojamatch, Ojama Blue, Armed Dragon Thunder or A-Assault Core), add the Ojama Trio or an ABC/Armed Dragon engine piece, and build toward a Fusion or Link boss
• Turn 2 (going second): No hand traps or negation in the Main Deck, so the going-second plan relies on a search-based response to the opponent's board and on Ojama Duo or Ojama Delta Hurricane!! clearing the field
• Recovery: Multiple searchers and recursion from the graveyard (Ojamagic, Ojama Blue, Armed Dragon Thunder LV3/LV5, Ojama Pajama) let the deck rebuild its hand after a single disruption
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games in a best-of-three

Why it scores here

The deck reliably opens a search turn: 14 searcher-text cards give roughly 0.90 odds of at least one in a five-card opening hand, and that search reaches either the Ojama Trio or an ABC/Armed Dragon engine piece. It converts that search into board presence through Fusion and Link bosses such as ABC-Dragon Buster and A-to-Z-Dragon Buster Cannon, and into late-game 3000+ ATK threats, but the conversion depends on several specific pieces (Ojama Trio, ABC Union chain, Armed Dragon LV-chain) arriving together, which the probability model puts at roughly 0.64 for the seven-copy Ojama core and far lower for each individual engine. Its interaction is thin, with no hand traps or floodgates and only one negation-capable boss, so going second is the weakest phase. The score rests on the system's redundancy and closing power, not on popularity: the Ojama archetype accounts for only 17 of the 40 Main Deck cards, and no combo boards were recorded, so median output and ceiling are text-inferred. Individual card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 50.6, Going First ≈ 52, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: engine conflicts (-3); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample); 0.80*50.6 + 0.20*45 - 5 = 44.5 rounded to 44

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.36 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher text (14 cards) gives a high chance of a functional first turn
• Three engines (Ojama, ABC, Armed Dragon) offer alternative routes
• Strong Extra Deck bosses (3000 to 4000 ATK) with banish, negate and destroy effects
• Extra Deck fully used with flexible Link and Fusion options

Weaknesses

• No hand traps, floodgates or Main Deck negation
• No Side Deck, so no post-side adaptation
• Low exact-name archetype purity (30.9%) and mixed sub-archetypes reduce engine coherence
• Going-second interaction is thin

Critical choke points

• The Ojama Trio requirement for Ojama Delta Hurricane!! and the ABC Union chain both need specific pieces together
• Single-copy ABC and Armed Dragon engine cards make the Extra Deck bosses hard to reach

Recommended changes

Evidence & confidence

• Verified: Legality: 40 Main, 15 Extra, 0 Side, all cards Unlimited or Limited within copy limits; Card text for each listed card (searchers, removal, Extra Deck bosses); Extra Deck breakdown: 6 Fusion, 7 Link, 2 XYZ; Archetype purity counts (17 Ojama, 13 ABC, 10 Armed Dragon)
• Observed: Usage statistics: 4 of 9 core cards present (44.4%)
• Inferred: Engine accessibility P(at least one starter) about 0.90 for searcher-type cards; Ojama core P(at least one in hand of 5) about 0.64; Full-brick proxy about 0.36; Going-second weakness from absence of hand traps and negation
• Provisional: Meta power (no dated metagame sample); Matchup fit (no tournament context)
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot match record are absent no win-rate telemetry exists in YGOVN, so going-first, going-second and matchup values are Inferred or Unknown Meta power is Provisional unless a dated metagame sample is supplied no side deck was registered, so post-side performance cannot be assessed
