Tachyon Deck #768280 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 53 / Extra 14 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Xyz Summon a high-ATK Galaxy-Eyes or Tachyon boss (Number C107, Number 62, Galaxy-Eyes Full Armor Photon Dragon) off Galaxy-Eyes and Photon starters, then protect it with negation and hand traps.; Galaxy Soldier and Galaxy Wizard searches assemble Galaxy Photon Dragon or Antimatter Dragon chains for incremental pressure.
• Turn 1 (going first): Open a Level 4 or Level 5 LIGHT starter (Galaxy Soldier, Galaxy Wizard, Photon Jumper) and search a Galaxy or Photon card, then build an Xyz off the field.
• Turn 2 (going second): Hold Ash Blossom and Tachyon Transmigration to negate the opponent's first effect, then continue the Xyz line on the next turn; the hand trap count gives roughly a 0.31 chance of at least one in six cards.
• Recovery: Galaxy Summoner and Photon Emperor recur Photon and Galaxy monsters from the GY; Galaxy Journey and Galaxy Expedition return or re-summon after a board wipe.
• After siding: Not evaluable: the side deck is empty, so there is no post-side plan.

Why it scores here

The deck is scored as a system, not as an average of its card scores. Its Xyz engine reliably reaches a Level 4 or Level 5 starter on turn 1 (about 0.74 for at least one archetype-core card in a 5-card opening hand, Inferred), and the Galaxy search chain gives it recurring access to Photon and Galaxy resources. Three Ash Blossom and several Tachyon negation effects provide real interaction, and the Number C107 and Number 62 bosses supply closing power. The score is held down by the illegal list (three Ash Blossom and two Seventh Tachyon in an OCG format limited to two and one), the lack of any recorded combo data, the 53-card main deck (13 cards above the 40-card minimum, many single copies), and the empty side deck. Archetype popularity did not earn points; the deck has no tournament link, so Meta Power is provisional and the matchup dimension is a low-confidence placeholder.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-12). Final formula: No reliable metagame: 0.80*Structural(49) + 0.20*TournamentReliability(40) + ContextModifiers(-12) = 35, then capped to 30 because the list is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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 Xyz and Galaxy-Eyes boss suite with high ATK closers
• Layered interaction: 3 Ash Blossom, Tachyon Transmigration and Schwarzschild negation
• Recursion and searchers (Galaxy Summoner, Photon Emperor, Galaxy Soldier) support grind

Weaknesses

• Illegal list: over-limit Ash Blossom and Seventh Tachyon
• 53-card main deck with 17 singletons and off-archetype copies
• No side deck and no post-side plan

Critical choke points

• Turn-1 Level 4 or Level 5 LIGHT starter must be drawn for the Xyz line
• Extra Deck Xyz material setup is required for every boss

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom 3 vs 2 allowed; Seventh Tachyon 2 vs 1 allowed; Main 53, Extra 14, Side 0 against OCG size rules; Archetype usage: 12 core cards, 6 present
• Inferred: Starter access 0.74 for archetype core in opening 5; Hand-trap access 0.31 going second; Interaction breadth from text roles
• Provisional: Meta Power; Matchup fit and format fit (no dated metagame sample)
• 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 One main-deck passcode (10443957) did not resolve to a card No win-rate telemetry in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied
