Tachyon Deck #771063 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Midrange, 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 boss pressure from the Extra Deck (Number 107: Galaxy-Eyes Tachyon Dragon, Number C62, Number 38 absent, Galactic-style Xyz bosses), converted through Tachyon and Ryzeal Xyz material loops; Ryzeal Detonator and Ryzeal Duo Drive board-control and ATK pressure once a Rank 4 Xyz is on the field
• Turn 1 (going first): Open a Tachyon or Ryzeal starter (Tachyon Cloudragon, Ice Ryzeal, Star Ryzeal, Ext Ryzeal) and extend into a Rank 4 Xyz; hold Ash Blossom and Ghost Ogre for the opponent's first interaction
• Turn 2 (going second): Use the 6-card hand's Ash Blossom, Infinite Impermanence and Ghost Ogre to stop the opponent's opening, then rebuild through Seventh Ascension and the Galaxy-Eyes Tachyon Primal search line
• Recovery: Recover through Ryzeal Plugin and Ryzeal Cross to re-summon Xyz monsters from the GY, and Schwarzschild Infinity Dragon as a second body
• After siding: Not evaluable: the list has zero Side Deck cards, so there is no post-side plan

Why it scores here

The deck is scored as a system, not by averaging card scores. Its interaction suite (three Ash Blossom, two Infinite Impermanence, three Ghost Ogre, three Schwarzschild) gives it real breadth against the opponent's first moves, and the Extra Deck supplies high-ATK Xyz bosses that close games. The engine is fragmented: only 3 of 16 archetype-standard core cards are present, the exact-name Tachyon purity is 5.5%, and the Ryzeal and Galaxy-Eyes threads share few conditions, so the opening-hand starter rate is modest (P at least one Tachyon starter in 5 cards is about 0.34 for a 3-copy card). Popularity earned no points: the archetype is listed in usage statistics but the deck's list diverges from it. The list is Illegal under OCG copy limits (four cards over the limit), so the score is capped at 30 and labelled theoretical and structural-only, with no combo, tournament, or side-deck evidence to lift confidence.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (not applied; structural only). Structural ≈ 53, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-12). Final formula: No reliable metagame: 0.80*Structural (52.6) + 0.20*TournamentReliability (40) = 50.1; modifier -12 (banlist exposure) gives 38.1; Illegal cap sets the final score to 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 interaction: 8 hand traps, 13 negation-text cards and 11 removal-text cards
• Strong Extra Deck closers with 3000 to 4000 ATK
• Redundant Tachyon and Ryzeal searchers (13 searcher-text cards)

Weaknesses

• Illegal under OCG copy limits: four cards over the limit
• Low exact-name purity (5.5%) and 52 off-archetype copies, so the engine is fragmented
• No side deck, so no post-side adaptation

Critical choke points

• Rank 4 Xyz access: most lines need a Rank 4 Xyz on the field before the boss is reached
• Restricted starters (Ext Ryzeal, Ice Ryzeal, Sword Ryzeal) are limited to one copy each in OCG

Recommended changes

Evidence & confidence

• Verified: Four copy-limit violations in OCG (legal copies from banlist field); Main 40, Extra 15, Side 0 counts; Exact-name purity 5.5% and 3 of 16 core cards present; Zero side-deck cards
• Inferred: Starter access about 0.34 for 3-copy starters and about 0.69 for the core group in hand 5; Hand-trap coverage about 0.76 at least one in going-second hand 6; Interaction breadth, going-second strength, and Xyz closing power from card text
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (no tournament link)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry; going-first and going-second splits are Inferred Meta Power is Provisional unless a dated metagame sample is supplied No side deck; post-side performance unknown
