Tachyon Deck #773077 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun, Combo
• 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 Summon a Rank 8 to Rank 10 Galaxy-Eyes or Photon boss (4000 ATK options such as Galaxy-Eyes Cipher X Dragon, Number 62, Full Armor Photon Dragon) and attack through a hand-trap-protected board; Galaxy Photon Dragon and Galaxy-Eyes Tachyon Primal as lower-cost Xyz and Link pressure once the Photon/Galaxy search chain starts
• Turn 1 (going first): Turn 1 Normal Summon a Level 4 Photon or Galaxy searcher (Photon Orbital, Galaxy Soldier, Galaxy Wizard) to reach a Level 4 Xyz pair, then hold Ash Blossom and Infinite Impermanence for the opponent's answer
• Turn 2 (going second): Open with Ash Blossom, Droll & Lock Bird, or Infinite Impermanence to stop the opponent's first search or summon, then rebuild a Galaxy-Eyes board from the GY through Galaxy Summoner and Galaxy Expedition
• Recovery: Search effects (Galaxy Soldier, Photon Orbital, Photon Jumper, Galaxy Wizard) and the Photon/Galaxy GY recursion from Galaxy Summoner and Galaxy Photon Dragon refill the hand after a hand trap is spent
• After siding: No Side Deck is registered, so the deck has no post-side plan and cannot adapt between games in a best-of-3 event

Why it scores here

This deck is scored as a connected Midrange Xyz system and not as an average of its card scores, and its legality cap applies. The archetype core group (11 copies) gives about an 82 percent chance of at least one core card in a 5-card opening hand, so the engine usually comes online, though the two Galaxy-Eyes Photon Dragon copies are individually unlikely to open (about 24 percent). Interaction is the strongest part of the list, with 7 hand traps and 12 negation-text cards, and the 4000-ATK Xyz finishers give it real closing power once a board is established. The weak points are the 9 tech and dead-in-hand cards, the lack of a side deck, and no recorded boards or tournament data, so the ceiling and median cannot be measured. Popularity and archetype usage were not credited. The illegal copy counts (3 Seventh Tachyon against a limit of 1, 3 Ash Blossom against a limit of 2) cap the score and the result is structural and theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53.6, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: copy-limit violations (Illegal) (-12). Final formula: Illegal legality cap applied: no-meta formula 0.80*53.6 + 0.20*40 = 50.9, then context modifier -12 gives 38.9, rounded to 39 (theoretical/structural only; Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• Core Xyz engine is accessible (about 82% for at least one core card in a 5-card hand)
• Dense interaction: 7 hand traps and 12 negation-text cards
• Strong Xyz finishers at 4000 ATK in Extra Deck
• Multiple search and recursion routes through Photon and Galaxy

Weaknesses

• Copy-limit violations on Seventh Tachyon and Ash Blossom make the list illegal as built
• No Side Deck
• 9 tech/narrow cards risk dead draws
• Lack of recorded boards means the combo ceiling and median cannot be measured

Critical choke points

• Single-copy Droll & Lock Bird and Harpie's Feather Duster are narrow answers
• Galaxy-Eyes Photon Dragon has only 2 copies, so the Xyz engine can stall without it

Recommended changes

Evidence & confidence

• Verified: Legality: Seventh Tachyon 3 vs 1 legal; Ash Blossom 3 vs 2 legal (Illegal); Main 40, Extra 15, Side 0 counts; Card text for hand traps, searchers and Xyz bosses; Archetype core usage (11 copies, 82% at least one)
• Inferred: Hypergeometric opening-hand consistency (D1, D2); Interaction density and going-second board-breaking from text (D7, D8); Brick risk from tech and narrow cards (D2)
• Provisional: Meta Power and D13 matchup fit (no dated sample or 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 Side Deck: post-side plan cannot be assessed no win-rate telemetry for OCG; going-first and going-second splits are Inferred Meta Power is provisional without a dated metagame sample
