Gagaga Deck #768399 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 61/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Xyz Summon a 2500-3000 ATK Utopia/Number boss (Number 39: Utopia, Number 99: Utopia Dragonar, Number F0: Utopic Draco Future, Number 38) from a Gagaga/Zubaba/Gogogo/Dododo swarm of Level 4 monsters.; Gagagaga Girl and Gagagaga Magician recover board presence from the GY and steal or negate opposing monsters.
• Turn 1 (going first): Turn 1: Onomatopaira or Gagaga Magic. Gagaga Magic special summons itself plus a Zubaba/Gagaga/Gogogo/Dododo monster from hand or GY, then Xyz Summons (Gagaga Magician/Girl, Utopia boss) while Zubababancho or Goblindbergh extends.
• Turn 2 (going second): Without a hand trap, the second player relies on Forbidden Droplet x2, Unbreakable Xyz Barrier, Overlay Network, and Number 39: Utopia / Number 38 negations to stop the first player's Xyz. Recovery is the same Gagaga Magic / Dododo swarm.
• Recovery: Onomatopaira and Onomatopickup search the deck; Dodododwarf Gogogoglove and Onomatokage recur from the GY; Gagagaga Girl and Astraltopia turn spent monsters into searches.
• After siding: None: the deck runs 0 side-deck cards, so there is no post-side plan.

Why it scores here

The deck reliably opens a functional plan: four Level 4 or 6 monsters (Gagaga Magician, Zubababancho, Goblindbergh, Dododo Warrior) are redundant starters, and Onomatopaira plus Onomatopickup search the lane. The Structural score (65.6) comes from consistency, a searcher-dense engine, and Xyz closing power on the system, not from averaging card scores or from Gagaga being a popular archetype. Conversion and median output are unmeasured because the evidence has no recorded boards, so D3 and D4 are Inferred text reads, and D4 is kept near the middle. The deck survives one interruption through several independent starters, but it has no hand traps and no side deck, so it is weak going second and has no post-side adaptation. Confidence is Medium: the list is legal and text-rich, but there are no combos, no meta data, and a usage-stat mismatch on Extra Deck cards.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 65.6, Going First ≈ 66, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: no_side_deck (-2); engine_spread_off_plan (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*65.6 + 0.20*60 - 4 = 60.5, rounded to 61 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · 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

• Redundant engine starters (Gagaga Magic, Zubababancho, Goblindbergh, Dododo Warrior) and searchers (Onomatopaira, Onomatopickup, Gagagaga Girl)
• Strong Extra Deck closers at 2500-3000 ATK
• Compact 40-card main with 13 singletons and little dead tech

Weaknesses

• No hand traps or floodgates, so going-second interaction is reactive and thin
• Zero side-deck cards
• Extra Deck spread across off-plan sub-archetypes (Galaxy-Eyes, Hope Harbinger, Number 99)

Critical choke points

• Gagaga Magic / Zubaba-Gogogo-Dododo monster access in the opening hand (about 0.85 for at least one core opener in opening 5)
• Single Xyz Summon of the boss (Number 39 / Number 99) into an opposing negation

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0, legal OCG list with 0 violations; Reinforcement of the Army is Limited with 1 copy run, within the legal limit; Hypergeometric draw odds for 3-copy cards (0.3376 hand5 / 0.3943 hand6) match the export
• Observed: Usage stats show the Gagaga core is standard (Gagaga Magician, Goblindbergh, Dododo Warrior at 100% inclusion)
• Inferred: Engine consistency and at-least-one starter probability (~0.85); Going-second weakness from no hand traps; Xyz conversion ceiling from card text
• Provisional: Meta Power (null), matchup fit and tournament reliability
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta share and per-pilot record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred Meta Power is Provisional without a dated metagame sample Usage-stat missing_core and in_this_deck flags appear to be computed against the Main Deck only: Extra Deck cards such as Gagagaga Girl, Number F0: Utopic Future Zexal and Gagagaga Magician are listed as absent even though cards[] shows them in the Extra Deck, so core_present_pct (48%) is understated Deck title is null
