Gagaga Deck #770798 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 48 / Extra 22 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz Summon Utopia / Number Xyz monsters (Number 99: Utopia Dragonar, Number 39: Utopia, Number 99: Utopic Dragon) from a Gagaga/Utopia/Dododo search-and-summon engine; Interaction-backed attrition: Dark Hole, Raigeki, Harpie's Feather Duster and hand traps clear the board so Xyz monsters can attack
• Turn 1 (going first): Search Onomatopaira or Onomatopickup, normal summon a Level 4 monster, pivot into a Level 4 Xyz (Gagagaga Magician / Number 39: Utopia Rising) and protect it with Unbreakable Xyz Barrier or Ash Blossom
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Maxx C and Infinite Impermanence to answer the first search or summon, then rebuild a board from Gagaga Ganbara Knight and Dodododo Warrior
• Recovery: Reuse the graveyard: Onomatokage and Dodododwarf Gogogoglove can be special summoned back from the GY, and Gagagaga Girl (Extra) can re-add engine cards from the deck
• After siding: No side deck is registered, so no post-side plan can be verified; the evidence supports only the main-deck plan

Why it scores here

This 48-card Main deck has a real engine: 15 searcher-text cards give an 86% chance of at least one search in a five-card opening hand, and the archetype core group is open in about 98% of hands. Its interaction suite (eight hand traps, twelve negation texts, Dark Hole, Raigeki and Feather Duster) is broad, which drives the end-board and resilience scores. Offensively, the Extra Deck supplies several 3000-plus ATK Number and Utopia Xyz monsters, but the Extra Deck holds 22 cards against a 15-card limit, so the list is illegal and the final score is capped low by the legality rule. No combos, guides or tournament data were supplied, so floor, median and ceiling are text-only inferences. Popularity of the archetype and the card-level scores were not averaged into this deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: extra_deck_over_size_limit (-12). Final formula: Illegal cap: Structural 57.4 (Midrange profile) and TR 48 would give about 55 under the no-meta formula, but the rule for an Illegal deck caps the final contextual score low; reported as 25 (theoretical/structural-only, Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · 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

• Searcher density: 15 searcher-text cards, 86% chance of a search in a five-card opening hand
• Layered interaction: 8 hand traps, 12 negation texts, Dark Hole, Raigeki and Harpie's Feather Duster
• Recursion from the graveyard for rebuild after disruption

Weaknesses

• Extra Deck over the 15-card limit (22 cards), which makes the list illegal
• No side deck, so no post-side plan can be verified
• Only 11.4% exact-name Gagaga purity; heavy off-archetype tech dilutes the engine
• Xyz/Level-4 requirements make early board conversion dependent on specific pairs

Critical choke points

• Extra Deck size must be cut to 15 before the list can be played in an event
• Level 4 Xyz base (Gagagaga Magician, Number 39: Utopia family) gates most of the board conversion

Recommended changes

Evidence & confidence

• Verified: Extra Deck size 22 exceeds the OCG maximum of 15; All restricted cards are at or under their legal copy limits (Limited and Semi-Limited); Main Deck size 48 is within the 40-60 range; Side Deck contains 0 cards
• Observed: Archetype purity 11.4% exact-name Gagaga; 62 off-archetype copies (from composition)
• Inferred: Searcher hit probability 0.86 and archetype core group open 0.98 (hypergeometric); Interaction density and going-second hand-trap hit rate 0.69; Recursion and rebuild potential from card text
• Provisional: Meta Power (no dated metagame sample); Matchup fit (no 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) Meta Power is Provisional unless a dated metagame sample is supplied Side Deck is empty; post-side plan unverifiable Deck title is null; deck identified by id and archetype only
