Legality

Main 56 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

Win condition: Extra Deck boss monsters (ABC-Dragon Buster, A-to-Z-Dragon Buster Cannon, Armed Dragon Catapult Cannon) built from ABC/Armed Dragon/Ojama support, if the list were legal; Link and Synchro beaters (Saryuja Skull Dread, Knightmare Phoenix, Ancient Fairy Dragon) as extra pressure
Turn 1 (going first): Opening starters (Ojamatch, Ojamassimilation, Union Hangar, Ojama Blue, Ojama Pajama) to find Union/ABC pieces; unverified because no recorded boards exist
Turn 2 (going second): Ojama Duo or Ojama Green/Yellow/Black tokens and Ojamagic to build blockers, then Union equips into a Fusion; unverified
Recovery: Ojama Blue and Ojama Duo recursion from GY plus Therion Discolosseum and Union Hangar searches; inferred from text only
After siding: Not evaluable: the deck has no side deck (side_count 0)

Why it scores here

The list is illegal in master-duel: Terraforming, Chaos Ruler and Apollousa are Forbidden and each is run at 1 copy, and it is 56 Main and 15 Extra cards with no side deck. Under the illegal-deck rule this is a structural-only read capped low, not a normal Final Contextual score. Structurally the list is scattered: exact-name Ojama purity is 23.9%, with its 54 off-archetype copies spread across ABC, Armed Dragon, Therion, P.U.N.K. and generic cards, so the engine is not coherent. Its consistency is estimated from the hypergeometric table (P(at least one of a 3-copy starter in a 5-card hand) = 0.25, Inferred) and it has no recorded boards, so its conversion, floor and median cannot be measured. The score does not come from Ojama being a popular archetype, and it does not come from averaging card scores.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	45	P(>=1 of a 3-copy starter in 5 cards) = 0.25; starters are spread across several sub-archetypes; no usage core is present (Inferred)
D2	Opening-Hand Quality & Brick Management	35	Hand-quality estimate from the copy histogram and 14 distinct extra-deck targets; the Ojama and ABC pieces conflict in hand (Inferred)
D3	Combo Conversion & Ceiling	40	No parseable boards; the ceiling rests only on card text such as the ABC Fusion chain and Union equips (Inferred)
D4	Combo Floor & Median Output	35	No combo median is available; the floor is unmeasured and the deck is expected to be inconsistent (Inferred)
D5	Interruption Resilience & Route Redundancy	45	Several independent routes exist (Ojama Duo/Blue recursion, Union Hangar searches), but no measured resilience (Inferred)
D6	Resource Economy, Recovery & Grind	50	Recursion and search text is abundant (24 searcher hints); resource use is only text-inferred (Inferred)
D7	End-Board & Interaction Quality	40	Three negation/removal hints (Forbidden Droplet, Emergency Teleport, Ojama Pajama) and a few destroy effects; no measured interaction density (Inferred)
D8	Going-Second & Board-Breaking Power	40	Going-second split is unavailable; Ojama tokens and Union blockers are plausible but unmeasured (Inferred)
D9	Offensive Pressure & Closing Power	45	Extra Deck bosses reach 3000 to 4000 ATK by text, but no end-board observations exist (Inferred)
D10	Main Deck Efficiency & Flexibility	35	56 Main cards with 33 distinct names and 22 level-0 non-monsters; the list is bloated with low-synergy copies (Verified count, Inferred efficiency)
D11	Extra Deck Efficiency & Coverage	55	Extra Deck is 15 cards with Fusion/Link/Synchro coverage and several boss routes, but cards are split between two engines (Inferred)
D12	Side Deck Adaptability	20	No side deck exists; the score is floored (Verified)
D13	Matchup Coverage & Format Fit	25	No tournament link and no archetype meta-share; format fit is provisional (Provisional)
D14	Pilotability & Error Tolerance	30	Multi-step Union and Fusion chains with many decision points; error tolerance is weak (Inferred)

How the score was computed

Strategy profile: Balanced (default; no single strategy clearly dominant). Structural ≈ 40, Going First ≈ 38, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: Illegal list cap (-15); No side deck (0); Scattered archetype core (0). Final formula: Illegal cap: structural-only (balanced weights, about 40). Not a normal Final Contextual score; Meta provisional, Tournament Reliability about 30

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.25 · 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 search and recursion text (24 searcher hints) that smooths draws (Inferred)
Extra Deck with several boss routes (ABC-Dragon Buster, A-to-Z-Dragon Buster Cannon, Armed Dragon Catapult Cannon) (Verified text)
Ojama tokens and Ojama Duo give some going-second board presence (Inferred)

Weaknesses

Illegal in master-duel: three Forbidden cards at 1 copy each (Verified)
Low exact-name purity (23.9%) and cards split across ABC, Armed Dragon, Therion and P.U.N.K. (Verified count)
No side deck (Verified)
No recorded boards, so no combo floor or median (Verified gap)

Critical choke points

The Forbidden Terraforming, Chaos Ruler and Apollousa copies must be removed before the list is legal
The ABC Union/Fusion chain depends on a few Union Machine pieces and one Fusion (Inferred)

Recommended changes

Priority	Remove	Add	Reason
1	Terraforming, Chaos Ruler the Chaotic Magical Dragon, Apollousa Bow of the Goddess	Legal replacements that keep the deck's role (search or negation), chosen by the builder	The deck is Illegal in master-duel, so no normal score applies until these are removed (Verified)
2	Off-archetype tech and loose splash copies	Consolidate onto one main engine (ABC or Armed Dragon, or Ojama)	Exact-name purity is 23.9%; a single engine should raise D1 and D2 (Inferred)
3	Low-value copies of non-engine cards	A small side deck (up to 15) of matchup answers	A side deck is empty, so D12 is floored at 20 (Verified)

Evidence & confidence

Verified: Illegal: Terraforming, Chaos Ruler and Apollousa are Forbidden in master-duel; Main 56 (within 40-60), Extra 15 (within 0-15), Side 0; Exact-name Ojama purity 23.9% with the archetype spread listed; No combos, no tournament link and no guides
Inferred: Starter access 0.25 for a 3-copy card in a 5-card opening hand (hypergeometric); Brick and conflict risk from the mixed archetype spread; Boss routes and interaction value from card text only
Provisional: Meta Power and format fit, since no dated metagame sample is supplied
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 Meta Power is Provisional unless a dated metagame sample is supplied No side deck supplied, so post-side adaptability cannot be assessed
