Deck — Deck Power Evaluation

• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Xyz Summon a Rank 4 boss (Number F0 Utopic Draco Future, Super Starslayer TY-PHON, Cairngorgon, Photon Papilloperative) off the Zubaba/Gagaga/Gogogo/Dododo engine, with Onomatopaira searching the monsters needed each turn; Gagaga Cowboy and Gagagaga Girl recurring the engine through the Graveyard, with hand traps and Forbidden Droplet/Crossout Designator stripping the opponent's interaction
• Turn 1 (going first): Turn 1 Onomatopaira (or Gogogo Goblindbergh / Dododo Warrior Normal Summon) to search a Dododo/Gagaga/Gogogo/Zubaba monster, Special Summon the Onomat chain into a Rank 4 Xyz, and protect the board with Ash Blossom, Infinite Impermanence and Effect Veiler
• Turn 2 (going second): Hold 2-3 hand traps (Ash Blossom, Infinite Impermanence, Droll & Lock Bird, Maxx C, Effect Veiler) to answer the opponent's first summon or search, then rebuild the same Onomat engine on the following turn
• Recovery: Onomatopaira, Gagaga Ganbara Knight and Zubaba Knight re-search the engine monsters, and Gagagaga Girl recovers searchers from Xyz material; the Graveyard recursion (Onomatokage, Dodododwarf Gogogoglove) rebuilds boards after a single interruption
• After siding: No Side Deck is registered (Side Deck size 0), so there is no post-side plan; the deck relies on its main-deck tech (Reinforcement of the Army, Crossout Designator, Forbidden Droplet) for every matchup

Why it scores here

The deck opens its engine reliably: Onomatopaira is three copies, fourteen cards carry searcher text, and P(at least one searcher in a 5-card opening hand) is about 0.90 (Inferred from the hypergeometric table), so the Zubaba/Gagaga/Gogogo/Dododo chain is live on most openings. It converts that engine into Rank 4 Xyz bosses and a strong closing board, scored on the system, not on any individual card. Its interaction is layered across ten hand traps, several Trap Holes, Forbidden Droplet and Crossout Designator, which earns the going-second and endboard-quality scores. The floor and median are scored separately and lower than the ceiling, because no recorded boards exist to measure them and the Xyz chain has many single-copy links. Popularity and usage data confirm the list is real and close to the archetype core, but they did not earn points by themselves; no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: 80% Combo / 20% Stun for the structural blend; Combo profile used as the structural base. Structural ≈ 68, Going First ≈ 66, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: Banlist exposure (-2); Engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample): 0.80*68 + 0.20*60 - 4 = 62

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

• Engine starts reliably from searchers (14 searcher-text cards, Onomatopaira x3)
• Ten hand traps plus Trap Holes and Forbidden Droplet give layered interaction
• Rank 4 boss options at 2900-3000 ATK with recursion through the Graveyard

Weaknesses

• No recorded boards or win-rate data; floor and median cannot be measured
• Fifteen single-copy Xyz across nine sub-archetypes dilutes engine cohesion
• No Side Deck; no post-side adaptation

Critical choke points

• Turn-1 Onomatopaira or Gogogo/Dododo Normal Summon: the whole engine stops without an engine monster in hand
• Single-copy Rank 4 bosses (Number F0 Utopic Draco Future, Super Starslayer TY-PHON, Cairngorgon) have no second route

Recommended changes

Evidence & confidence

• Verified: Legal: 40 main, 15 extra, 0 side; all four Limited and Semi-Limited cards run at legal copies (legality block); 14 searcher-text cards and 10 hand traps by role tag counts; Archetype core present at 56% of usage-stat core cards (usage statistics)
• Inferred: P(at least one searcher in 5 cards) about 0.90 (hypergeometric estimate); Ceiling and floor of the Xyz chain from card text only (no combo boards); Going-second hand-trap coverage from the 6-card hand estimate
• Provisional: Meta Power is null; no dated metagame sample or tournament link; Matchup fit and side-deck adaptability cannot be measured
• Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN; going-first/second, matchup and brick rates are Inferred usage statistics in this deck flags disagree with the cards array for several Extra Deck cards (for example Number F0: Utopic Future, Evilswarm Exciton Knight, Tornado Dragon, Gagagaga Magician); the cards array was used as the source of truth Meta Power is provisional unless a dated metagame sample is supplied
