Onomat Deck #770665 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz bosses from the Extra Deck, chiefly Number C104: Umbral Horror Masquerade (3000 ATK) and Number 69: Heraldry Crest - Dark Matter Demolition (3100 ATK); Dododo Warrior (2300 ATK) and Gorgonic/Umbral Horror pressure through Xyz material and negation
• Turn 1 (going first): Open on Umbral Horror or Dododo starters, search through Barian's Seventh Untopia and V Umbral Horror, then Xyz into a Masquerade or Number boss (Inferred from card text; no recorded boards)
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Droll & Lock Bird and Barian's Seal to answer the first summon or activation, then rebuild a Xyz board from the remaining hand (Inferred)
• Recovery: Recover through Gagagaga Girl and Umbral Horror graveyard effects and re-search through the Umbral Horror and Barian's searchers (Inferred from text)
• After siding: None. The deck has no side deck, so there is no post-side plan.

Why it scores here

This deck is scored as a system, not as an average of its card scores. The list is Illegal in OCG: Seventh Tachyon is run 3 times against a Limited limit of 1, and Ash Blossom & Joyous Spring is run 3 times against a Semi-Limited limit of 2. Under the rubric the result is capped at 30 and labeled theoretical and structural-only. Structurally the deck has a broad interaction package (7 hand traps, 9 negation-text cards, 13 removal-text cards) and about a 92% chance that the archetype-core group appears in a 5-card opening hand, which lifts its interruption and endboard scores. Its identity is thin: exact-name archetype purity is 0%, and it mixes Umbral Horror, Barian's, Dododo, Masquerade, Mulcharmy and Gorgonic pieces. Gorgonic's Extra Deck restriction also conflicts with the non-Number Xyz monsters. No combos, guides, tournament link or side deck were supplied, so floor and median output are unmeasured, and archetype popularity earned no points.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60, Going First ≈ 60, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-8); engine_conflict (-4). Final formula: No reliable metagame: 0.80*Structural(60) + 0.20*TournamentReliability(50) = 58; modifiers -12 gives 46; Illegal-deck cap applied -> 30 (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Broad interaction package: 7 hand traps, 9 negation-text cards and 13 removal-text cards
• Archetype-core group reaches a 5-card opening hand about 92% of the time (Inferred)
• Several Xyz bosses at 2700 to 3100 ATK

Weaknesses

• Illegal copy counts on Seventh Tachyon and Ash Blossom & Joyous Spring
• No side deck, so no post-side adaptation
• Weak archetype identity: 0% exact-name purity; Onomat support is limited to Onomatokage x2, Dodododwarf Gogogoglove x1 and Dodododo Warrior x3
• Gorgonic's Extra Deck restriction conflicts with CXyz Hope Chaos Barian Dragon x2 and Gagagaga Girl x1

Critical choke points

• The list cannot be played as built until Seventh Tachyon and Ash Blossom are cut to legal copy counts
• Barian's Seventh Untopia (x3) gates the Umbral Horror search line (Inferred from text)

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal (Seventh Tachyon 3 vs 1; Ash Blossom 3 vs 2); Main 40, Extra 15, Side 0; composition and copy histogram; Card text and stats for the Xyz bosses and hand traps; Exact-name archetype purity 0%
• Inferred: Hypergeometric opening-hand odds (0.92 archetype-core, 0.34 per 3-copy card, 0.71 hand-trap at 6 cards); Engine lines and interaction density read from card text; Gorgonic Extra Deck conflict; Going-first and going-second estimates
• Provisional: Meta power (null) and D13 matchup fit; Median and floor output (no combos)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) No side deck; D12 cannot be measured from performance usage_statistics marks Number F0: Utopic Future Zexal and Gagagaga Girl as missing from the deck, but both appear in the Extra Deck list (x1 each); the core-match is inconsistent and was not used Meta Power is Provisional without a dated metagame sample
