Tachyon Deck #774746 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Tempo, Toolbox
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Xyz Summon high-ATK boss monsters (Ryzeal Detonator, Number C104: Umbral Horror Masquerade, Number 104: Masquerade V, Mereologic Aggregator) from Ryzeal, Gagaga and Dododo engine lines; Ryzeal Duo Drive ATK-buff board plus recursion of Ryzeal monsters from the GY
• Turn 1 (going first): Open with a Gagaga/Dododo/Ryzeal starter, search or Special Summon a second body, and Xyz Summon a boss; hand traps (Ash Blossom, Infinite Impermanence) protect the first Xyz on the opponent's turn
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence and Nibiru as hand interaction against the opponent's first summon, then rebuild through Onomatopaira and Gagaga searches
• Recovery: Ryzeal and Gagaga monsters recycle from the GY (Ryzeal Cross, Ryzeal Duo Drive attach, Dododo Gogogoglove banish-revive); recovery is text-derived only
• After siding: Not evaluable: the deck has 0 side cards, so there is no post-side plan

Why it scores here

The list is Illegal in OCG: four cards exceed their copy limits (Seventh Tachyon 3 of 1, Ash Blossom 3 of 2, Ice Ryzeal 2 of 1, Sword Ryzeal 2 of 1), so the score is a capped theoretical structural read, not a normal contextual score. Structurally the deck can open a Xyz engine through Gagaga, Dododo and Ryzeal starters, with 17 searcher-text cards and 6 hand traps giving it real interaction and recovery on paper. Its 15 Extra Deck slots are all Xyz monsters with strong boss options, but the main deck is spread across three sub-archetypes (Ryzeal 10, Dododo 7, Seventh 6, Gagaga 5, Mulcharmy 4) with 0% exact-name Tachyon purity, which weakens engine cohesion. The deck has no side deck and no combo, tournament or win-rate evidence, so the going-first, going-second and meta reads stay Inferred or Provisional. Archetype usage shows only 2 of 11 core cards present, which means the list deviates from the standard build rather than earning points from popularity; card scores were not averaged into this result.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55.5, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-3). Final formula: Illegal list: theoretical structural-only. Uncapped blend 0.80*55.5 + 0.20*45 = 53.4, with modifiers -11 gives 42.4; capped at 30 per the Illegal rule. Meta provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ 0.42 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Multiple Xyz boss options at 2600 to 3000 ATK with end-board removal (Ryzeal Detonator, C104)
• Six hand traps and nine negation-text cards give strong interaction density on paper
• Searcher density (17 cards) supports consistent access to starters
• Extra Deck is fully used with broad Xyz rank coverage

Weaknesses

• Illegal as built: four cards exceed OCG copy limits, requiring 5 main deck cuts
• Main deck is 40 cards exactly at the minimum, so cuts push it below the legal main minimum
• Sub-archetype spread (Ryzeal, Dododo, Seventh, Gagaga, Mulcharmy) lowers engine cohesion
• No side deck
• Heavy reliance on 1-copy Limited engine cards (Ryzeal Detonator, Ext Ryzeal, Bonfire, Daigusto Emeral)

Critical choke points

• Limited-status Ryzeal and Seventh cards: any legal rebuild must replace copies, changing the engine
• Dependence on Xyz summons from the Extra Deck: opponent's Extra Deck interaction can stop the whole line
• No side deck: any matchup problem is unanswered between games

Recommended changes

Evidence & confidence

• Verified: Illegal status with 4 over-limit cards and exact copy counts (OCG BanList); Main 40 / Extra 15 / Side 0 counts and size rules; Card text and stats for all resolved cards; Hypergeometric draw odds for the resolved list; Archetype usage: 2 of 11 core cards present
• Observed: Usage statistics show a deviation from the standard core build
• Inferred: Engine consistency and brick estimates from hypergeometric odds and card text; Interaction density and recovery values from text-role hints; Going-first and going-second splits from card text
• Provisional: Meta power (null); Matchup and format-fit read (D13 = 40 neutral placeholder)
• Data gaps: Deck is Illegal: score is a capped theoretical read, not a normal contextual score No combos supplied, so 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 exists in YGOVN for this format Side deck is empty (0 cards) so post-side evaluation is unavailable Meta Power is Provisional unless a dated metagame sample is supplied
