Gagaga Deck #771345 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz boss from the Extra Deck (Ryzeal Detonator, Number 39: Utopia, Number 99: Utopia Dragonar, Number C39: Utopia Ray) built on Xyz chains that Gagaga, Dododo and Zubaba starters enable; Ryzeal Duo Drive and Gagagaga Girl as recovery Xyz that search and add Xyz/Onomat support
• Turn 1 (going first): Opening starters (Onomatopaira, Gogogo Goblindbergh, Dododo Warrior, Mulcharmy Fuwalos) search and summon into a Xyz; hand traps (Infinite Impermanence, Effect Veiler, Ash Blossom) protect the first Xyz
• Turn 2 (going second): Droll and Lock Bird, Maxx C, Effect Veiler and Ash Blossom disrupt the opponent's first board, then the Gagaga/Dododo starter chain rebuilds a Xyz
• Recovery: Mulcharmy Fuwalos and Purulia draw on the opponent's Special Summons; Onomatokage and Dodododwarf Gogogoglove recur from the GY
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games

Why it scores here

The deck is Illegal: one copy of Number 60: Dugares the Timeless is Forbidden in OCG, so it is capped and reported as a theoretical, structural-only read. Structurally, the Gagaga/Dododo starter chain (about 15 searchers and 26 archetype-core copies, P(at least one core card in a 5-card opening hand) ≈ 0.997) makes the engine reliably live on turn 1-2 (Inferred), and the 10 hand traps and 11 tech cards give it real interruption resilience. The 15-card Extra Deck of Utopia, Ryzeal and Number Xyz bosses supplies the closing power and interaction, but there are no recorded boards, so the floor, median and ceiling are text-only inferences and are kept separate. Popularity is not credited: the archetype core is present but the exact-name purity is only 9.1%, and no tournament or win-rate data exists, so Meta Power is null and Tournament Reliability is held near the middle. The score is not an average of card scores; it reflects how the engine, interaction and Extra Deck work as one system, and it is capped down because the list is illegal and has no Side Deck.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52.7, Going First ≈ 55, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-6); no side deck (-2). Final formula: Illegal deck: theoretical only. Raw formula 0.80*52.7 + 0.20*50 + modifiers(-8) = 44.2, capped at 25 because a Forbidden card is over the copy limit. Meta provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 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

• Dense searcher density (about 15 cards) keeps the starter chain live on turn 1-2 (Inferred)
• 10 hand traps and 11 tech cards give the deck several interruption options and a second line after disruption (Inferred)
• All 15 Extra Deck slots are real Xyz engines with strong ATK and negate/destroy text (Verified card text)

Weaknesses

• Illegal as built: Number 60 is Forbidden and over the copy limit (Verified)
• No Side Deck (Verified), so there is no post-side adaptation
• Low exact-name archetype purity (9.1%) and a spread of sub-archetypes weaken engine coherence (Verified composition)
• No combo corpus or win-rate data, so the ceiling and median are unmeasured (Verified absence)

Critical choke points

• Number 60 must be removed before the deck can be played legally (Verified)
• The opening Xyz depends on a single Gagaga/Dododo starter being in hand; hand-trap disruption on that Xyz collapses the line (Inferred)

Recommended changes

Evidence & confidence

• Verified: Number 60 is Forbidden and over the copy limit; the deck is Illegal; Main 40 and Extra 15 counts are inside the OCG size rules; Side 0 is legal; Limited and Semi-Limited cards are run within their legal copy counts; Card stats and text are taken from the resolved card list
• Observed: Archetype core inclusion and typical copy counts from usage statistics (core present 56%)
• Inferred: Starter and searcher consistency from hypergeometric odds; Interaction density and resilience from card text; Going-second and closing estimates from card text; Pilotability from the number of chain windows
• Provisional: Meta Power is null; D13 is provisional with no dated metagame sample; Tournament Reliability uses assumed values without tournament data
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) no Side Deck: post-side plan cannot be evaluated Meta Power is Provisional unless a dated metagame sample is supplied
