Gagaga Deck #591007 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Xyz
• Format: master-duel

Legality

Main 46 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz Summon high-rank Utopia / Number monsters (Number 99: Utopia Dragonar, Number 38, Ultimate Leo Utopia Ray) and close with 2500-3000 ATK boards, backed by hand-trap protection (Inferred); Gagaga / Zubaba / Gogogo / Dododo starter chains that search the next starter and extend into Xyz (Inferred)
• Turn 1 (going first): Open a Gagaga or Zubaba starter with searchers (Onomatopaira, Goblin Biker Grand Entrance, Gogogo Goblindbergh), extend into a Level 4 pair and Xyz Summon, keeping Ash Blossom and Infinite Impermanence up as hand-trap protection (Inferred)
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Maxx "C", Red Reboot) to slow the opponent's engine, then rebuild the board through Utopic Onomatopoeia or Zubababancho Gagagacoat (Inferred)
• Recovery: Gagaga Ganbara Knight and Onomatopickup/Astraltopia recursion chains rebuild a starter from hand and deck; Gagagaga Magician and Number 39 can revive from GY (Inferred)
• After siding: No Side Deck is registered (side_count 0), so there is no post-side plan; the deck cannot adapt between games (Verified)

Why it scores here

The score reflects the deck as a system: searcher density (19 searcher-text cards) and an 11-copy archetype core give a high chance of a live starter by turn 1, while the Extra Deck is fully committed to Xyz and the hand-trap suite (10 cards) adds layered protection. Conversion is credible on paper, but no recorded boards exist, so the ceiling and median are text-based inferences and the median is scored lower than the ceiling on purpose. Brick risk is moderate because many Level 4 starters and Xyz pieces compete for the same hand slots, and the deck has no Side Deck, so it cannot adapt between games. Two copy-limit violations (Maxx "C" at 2 copies, Called by the Grave, which is Forbidden) make the list illegal, so the Final score is capped at 30 as a theoretical, structural-only read; popularity and archetype share did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 57, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12); illegal cap (-13); no side deck (0). Final formula: Raw: 0.80*Structural(58) + 0.20*TournamentReliability(45) + banlist modifier(-12) = 43; capped at 30 because the deck is Illegal (theoretical/structural-only, no normal Final score). Meta Power provisional/null.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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 text (19 cards) gives a high chance of a live starter (Inferred)
• Layered hand traps and negates (Ash Blossom, Infinite Impermanence, Droll & Lock Bird, Red Reboot) for going-second interaction (Inferred)
• High-ceiling Number closers (Number 99, Number 38, Ultimate Leo Utopia Ray) (Verified stats)

Weaknesses

• Illegal list: Maxx "C" run at 2 copies (limit 1) and Called by the Grave (Forbidden) (Verified)
• No Side Deck, so no post-side adaptation (Verified)
• Low exact-archetype purity (9.8%) and many off-archetype copies lower engine coherence (Verified)
• No combo data, so conversion and median output cannot be measured (Verified gap)

Critical choke points

• Xyz Summon of a Rank 4 or higher Utopia/Number monster depends on a Level 4 pair being live; one dead starter in hand stalls the line (Inferred)
• Going-second turns rely on hand traps that can be blanked by the same negates the opponent holds (Inferred)

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Maxx "C" 2 copies vs limit 1; Called by the Grave is Forbidden; Main 46 / Extra 15 / Side 0 is within Master Duel size rules; Archetype purity 9.8%; 19 searcher-text and 10 hand-trap cards; No combos, tournament link or guides are attached
• Inferred: Starter P(>=1) and core-group probability from hypergeometric estimates; Hand-trap and negate density as going-second interaction; Xyz conversion and closing power from card text
• Provisional: Meta Power and matchup fit (no dated metagame sample); Going-second and post-side performance
• 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 for going-first/second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied deck title is null; name taken as archetype only
