Gagaga Deck #773042 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz Summon high-rank Utopia/Number/Gagaga monsters off Onomatopoeia and Zubaba/Gagaga/Gogogo/Dododo searches, then convert with 2500-3000 ATK boss monsters.; Dododo Warrior and Gogogo Goblindbergh pressure lines that feed Xyz materials when the Xyz line is disrupted.
• Turn 1 (going first): Turn 1 Onomatopaira or Onomatopickup to search a link-chain enabler, then Normal Summon a Level 4 searcher and Xyz Summon into Utopia/Number boss monsters. Structural only: no recorded boards to confirm the sequence.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Nibiru and Infinite Impermanence in hand to answer the opponent's first summon or activation, then rebuild the Xyz line from the Deck.
• Recovery: Searchers (Onomatopaira, Onomatopickup, Gagaga Ganbara Knight, Zubababa Knight) reload the hand; Gagaga Girl and Gagagaga Magician are absent so recovery relies on the Utopia and Number Extra Deck bosses.
• After siding: No side deck is registered (Side Deck size 0), so no post-side plan exists. Best-of-3 play is unsupported by this list.

Why it scores here

This list is Illegal (Ash Blossom & Joyous Spring is run 3 times against a Semi-Limited limit of 2), so it receives only a structural read and a capped score of 30, not a normal Final Contextual score. The structure reads as a Xyz-based Combo deck: the searchers (Onomatopaira, Onomatopickup, Gagaga Ganbara Knight, Zubababa Knight) reliably find Level 4 starters, and the 15-card Xyz Extra Deck supplies boss monsters at 2500-3000 ATK. Interaction is deep for the format (12 hand traps and about 10 negation and 10 removal effects), which supports the going-second read. Popularity, archetype usage stats and archetype-core coverage confirm the list is real and accessible but did not earn points, and no card scores were averaged into the result. The main weaknesses are the 9.9% exact-archetype purity (64 off-archetype copies across Dododo, Mulcharmy, Utopia, Zexal, Number, Onomat, Cyclone and others) and the absence of a Side Deck, which pull the score down. No combo boards, tournament link or guides exist, so floor, median and ceiling are Inferred from card text only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); engine conflicts (-4); illegal cap (-8.8). Final formula: Illegal list: uncapped 0.80*Structural(56) + 0.20*TournamentReliability(40) = 52.8, then modifiers (-10 banlist exposure, -4 engine conflicts) = 38.8, capped at 30 as an Illegal deck (theoretical/structural-only). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher suite (20 searcher-text cards) gives high access to Level 4 starters.
• Deep interaction for the format: 12 hand traps plus about 10 negation and 10 removal effects.
• Strong Extra Deck boss ATK (3000 Number 99 and Number 38, 2500 Number 39 and Utopia Ray).

Weaknesses

• Illegal: Ash Blossom & Joyous Spring over its Semi-Limited copy limit.
• Very low exact-archetype purity (9.9%) and many conflicting sub-archetypes.
• No Side Deck registered, so no post-side adaptability.
• No combo evidence, so floor, median and ceiling are unverified.

Critical choke points

• Ash Blossom & Joyous Spring copy count (must drop to 2 to be legal).
• The Xyz line depends on Level 4 searchers and Gagaga Magician / Gagaga Girl, which are absent from the list.

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom & Joyous Spring run 3 against a limit of 2 (Illegal).; Droll & Lock Bird, Harpie's Feather Duster and Reinforcement of the Army are Limited with 1 copy each (legal).; Main 56 and Extra 15 are within size rules; Side 0 is within [0,15].; Exact-archetype purity 9.9% (7 of 71 archetype-matching copies).; Dododo Warrior and Gogogo Goblindbergh are 100% and 90% usage core cards and are in the deck.; Extra Deck composition: 15 Xyz (verified from the deck list).
• Observed: Usage statistics show 14 of 25 archetype core cards present (56%); the missing core includes Gagagaga Magician and Gagaga Girl.
• Inferred: Archetype-core P(at least one in hand of 5) ~0.98 is a proxy estimate.; The searcher-driven Level 4 starter access supports D1 and the Combo primary strategy.; Interaction density (12 hand traps, about 10 negation effects) supports the going-second read.; Floor, median and ceiling are estimated from text only.
• Provisional: Meta Power is null because no dated metagame sample exists.; Matchup fit and tournament reliability depend on context that is absent.
• Data gaps: No combo boards, so the combo floor, median and ceiling are text-only inference. No tournament link, so archetype meta-share and per-pilot records are absent. No win-rate telemetry (going-first/second, matchup, brick or starter rates). Meta Power is provisional without a dated metagame sample. No Side Deck registered, so post-side evaluation is impossible.
