Gagaga Deck #772202 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz boss pressure from the Gagaga, Ryzeal and Dododo engine (Ryzeal Detonator, Ryzeal Duo Drive, Star Ryzeal, Gagagaga Girl) and the Ryzeal-based boards; Hand-trap-supported disruption that protects an Xyz board and turns single-card pressure into attrition
• Turn 1 (going first): Open Dodododo Warrior or Gogogo Goblindbergh, chain Onomatopaira or Bonfire-style searches into the Gagaga/Ryzeal core, then build an Xyz with Ext Ryzeal or Star Ryzeal as Ryzeal material; hold Ash Blossom and Effect Veiler for the opponent's first answer
• Turn 2 (going second): Use the six-card hand to hold Ash Blossom, Infinite Impermanence, Effect Veiler and Droll & Lock Bird against the opponent's first extension, then follow with Xyz summons from the Extra Deck
• Recovery: Recycle Ryzeal cards from the GY through Ryzeal Plugin or Ryzeal Cross and redeploy searchers (Onomatopickup, Astraltopia, Ext Ryzeal) to rebuild the Xyz board
• After siding: Not evaluable: the deck list has zero Side Deck cards, so there is no post-side plan in the evidence

Why it scores here

The deck's structural score is built from the system, not from its cards: the 17-copy archetype core (P of at least one core card in a 5-card opening hand is about 0.95) and the 15 searcher-text cards give it a reasonably reliable T1 engine, and 11 hand traps plus 11 negation-text cards give it real interaction density. Those strengths are offset by zero recorded boards, so combo ceiling and median output can only be inferred from card text, and by zero Side Deck cards, which leaves post-side adaptability at the floor. Three Forbidden cards (Evilswarm Ouroboros, Number 60, Number 41) make the list illegal in OCG, so the rubric caps the final score at 20 and the structural figure of about 50 is theoretical only. Popularity and archetype usage were not credited, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Toolbox secondary; Midrange weights used for structural score. Structural ≈ 50, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12); illegal_list_cap (-17). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*50 + 0.20*45 - 12 = 37, then capped at 20 because the deck is Illegal (theoretical/structural-only evaluation)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• Archetype core is heavily copied (17 cards), so the starter is usually present in an opening hand
• Broad interaction: 11 hand traps plus negation and removal text, with Ash Blossom at 2 copies
• Searcher text is dense (15 cards), which supports consistent card flow

Weaknesses

• Illegal in OCG: three Forbidden Extra Deck cards are run, so the list must be rebuilt before it is playable
• No Side Deck at all, so no post-side adaptability
• No recorded combos or win data, so ceiling and median are text-only inferences

Critical choke points

• Dependence on Ryzeal Detonator and Ryzeal-named Xyz materials for the strongest boards, with Limited copy restrictions on several Ryzeal cards
• Going-second plan relies on hand traps being in hand, which is the 0.876 probability at a 6-card hand

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: three Forbidden cards are run (Evilswarm Ouroboros, Number 60, Number 41); Main Deck 40, Extra Deck 15, Side Deck 0; size rules satisfied; Ash Blossom & Joyous Spring is run at 2 copies, which is the Semi-Limited maximum; Archetype core group of 17 copies in the Main Deck
• Inferred: Starter reliability P = 0.949 from hypergeometric estimate; Hand-trap P at 6 cards = 0.876; Going-first and going-second plans and interaction density from card text; Brick and median output estimates from text only
• Provisional: Meta Power is null; no dated metagame sample; D13 matchup fit is provisional
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta share and pilot match record absent No win-rate telemetry for this deck; brick, starter and matchup rates are inferred or unknown Side Deck is empty, so post-side performance cannot be assessed Meta Power is provisional unless a dated metagame sample is supplied
