Gagaga Deck #767470 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz boss pressure from the Gagaga/Dododo/Zubaba/Gogogo engine into Number 99 / Utopia / Divine Arsenal-class Xyz Monsters; Hand-trap and spell/trap-removal attrition (Ash Blossom, Infinite Impermanence, Forbidden Droplet, Lightning Storm, Harpie's Feather Duster)
• Turn 1 (going first): Open Onomatopaira or Gogogo Goblindbergh to search and set up Dododo/Gogogo for a Xyz Summon while holding Ash Blossom and Droll & Lock Bird for interaction (Inferred from text)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Nibiru and Infinite Impermanence to stop the opponent's first board, then rebuild an Xyz line from the Extra Deck (Inferred from text)
• Recovery: Onomatopickup / Onomatopaira / Gogogo search and Mulcharmy draw effects to refill the hand after interaction (Inferred from text)
• After siding: Not evaluable: side_count is 0, so no post-side plan exists in this list

Why it scores here

The deck's reliable opening depends on a large, redundant Gagaga/Dododo/Gogogo starter set, with an archetype-core group that is almost always present in the opening hand (about 0.99 proxy estimate, Inferred). Interaction is the strongest part of the system: 12 hand traps and several spell/trap removal cards give high interaction density, which lifts the going-second and end-board dimensions. The main weaknesses are the Mulcharmy block, whose draw effects require an empty field and conflict with the Gagaga and Dododo field presence, and the absence of any recorded boards, which leaves combo floor, median and ceiling as text-only inference. Ash Blossom is run three copies against a limit of two, so the list is illegal and receives a capped score rather than a normal Final Contextual score. Popularity was not credited, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; D13 dropped and weights renormalised over 95 (meta-neutral). Structural ≈ 57, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: illegal_copy_limit_violation (-8); engine_conflict (-2); no_side_plan (-2). Final formula: Illegal cap applied: min(0.80*Structural + 0.20*TournamentReliability + ContextModifiers, 40) = min(0.80*57 + 0.20*50 - 12, 40) => 40 (Meta provisional, not used)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap and spell/trap interaction (12 hand traps plus Lightning Storm and Feather Duster)
• Multiple overlapping starters with high archetype-core presence in the opening hand
• Strong Xyz finishers available from the Extra Deck (Number 99, Utopia Dragonar, Divine Arsenal)

Weaknesses

• Illegal list: three copies of Ash Blossom & Joyous Spring against a limit of two
• Mulcharmy block conflicts with the Gagaga/Dododo field presence
• No recorded boards, so the combo floor and median are unknown
• No side deck, so there is no post-side plan

Critical choke points

• Extra Deck Xyz summons depend on a successful Gagaga/Dododo/Gogogo board being in place
• Hand-trap timing for going-second plays depends on drawing Ash Blossom or Impermanence

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is over the Semi-Limited copy limit (3 run, 2 legal); Main Deck size 56 and Extra Deck size 15 are within OCG size rules; side_count is 0
• Inferred: Starter availability from the hypergeometric draw table; Interaction density from card text and role flags; Engine conflict between Mulcharmy and the field-presence cards
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit
• 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 and going-second splits are Inferred Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
