Onomat Deck #774909 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Stun, Xyz Mechanic
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz Summon high-ATK finishers (Number 104: Masquerade V, Number C104, Ryzeal Detonator, Number 69: Heraldry Crest - Dark Matter Demolition, CXyz Hope Chaos Barian Dragon) off Umbral Horror, Barian's and Ryzeal material loops; Board control through negation and destruction (Lightning Storm, Heavy Storm, Harpie's Feather Duster, Dimensional Barrier) followed by Xyz beats
• Turn 1 (going first): Open a searcher (Seventh Ascension, V Umbral Horror, Dodododo Warrior, Ext Ryzeal) to find Umbral Horror / Barian's pieces, reach a Rank 4 Xyz, and protect the first Xyz with Ash Blossom, Infinite Impermanence or Solemn Judgment
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Droll & Lock Bird, Maxx "C" or Ghost Ogre to stop the opponent's first starter, then rebuild through Umbral Horror searches; Solemn Warning and Solemn Judgment cover summons
• Recovery: Recursion through Barian's Hope, Shining Umbral Horror (draw on Umbral Horror summons) and Mulcharmy Purulia (draw engine) to rebuild the hand after a hand-trap or board wipe
• After siding: Not evaluable: the deck runs zero Side Deck cards, so there is no post-side plan for best-of-3 play

Why it scores here

The deck reliably opens a searcher-backed engine: the probability of at least one searcher-text card in a 5-card opening hand is about 0.86, and the Umbral Horror / Barian's core reaches a Rank 4 Xyz on turn 1 to 2 in most hands (Inferred). Its interaction density is high, with 14 hand traps and 19 negation-text cards, so it can stop a first starter or summon on either turn order, which earns the going-second and interaction scores. Median output is held back by 24 tech-tagged cards in a 55-card main deck and by the absence of recorded boards, so the combo ceiling is scored separately from the median and neither is treated as an average of card scores. Popularity and archetype usage statistics confirm the list is real and accessible but earned no points on their own. The deck is Illegal because Number 60: Dugares the Timeless is Forbidden in OCG and is run once; the structural result is therefore capped and reported as theoretical only.

Dimension scores

How the score was computed

Strategy profile: Combo profile for structural; Stun interaction emphasis disclosed as secondary; D13 dropped and weights renormalised (meta-neutral). Structural ≈ 61, Going First ≈ 62, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-6); Weak post-side plan (-4). Final formula: No reliable metagame: 0.80*Structural(61) + 0.20*TournamentReliability(50) = 48.8; context modifiers -10 give 38.8; capped to 30 because the deck is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.39 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Searcher density (17) and Umbral Horror / Barian's synergy give a consistent engine start
• 14 hand traps plus 19 negation-text cards provide layered interaction on both turn orders
• Multiple independent Xyz finishers at 2700 to 3100 ATK, so one removed finisher does not end the plan

Weaknesses

• Illegal list: Number 60 is Forbidden in OCG
• No Side Deck, so best-of-3 adaptation is impossible
• 24 tech-tagged cards dilute the 55-card main deck and raise brick rate
• Archetype label 'Onomat' does not match the contents (0% exact-name purity; the real engine is Umbral Horror / Barian's / Ryzeal / Seventh)

Critical choke points

• Forbidden Number 60 must be removed before any normal score applies
• The Umbral Horror starter count is limited, so a hand without a searcher or starter stalls the first Xyz
• Several singleton Limited cards (Ryzeal Detonator, Ext Ryzeal, Solemn Judgment) are single points of failure

Recommended changes

Evidence & confidence

• Verified: Illegal status from Number 60 (Forbidden, 1 copy in Extra); Main 55, Extra 15, Side 0 counts; Banlist status for all Limited and Semi-Limited cards; Hand-trap, searcher, negation and removal text counts
• Observed: Usage stats show the core Dodododo Warrior at 3 copies and 90% inclusion
• Inferred: Consistency estimates from hypergeometric probabilities; Going-first and going-second hand-trap and starter access; Median and ceiling estimates from card text alone (no combos); Interaction quality from semantic reads of negation and removal text
• Provisional: Meta Power (null) and D13 matchup/format fit: no dated metagame sample; Tournament reliability estimate
• 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, going-second, matchup and brick rates are Inferred Archetype label 'Onomat' does not describe the deck's contents; the evidence's archetype_spread is used instead Meta Power is Provisional without a dated metagame sample
