Tachyon Deck #768219 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: ocg

Legality

Main 55 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra-Deck Xyz/Photon/Galaxy-Eyes boards with 3000-4500 ATK monsters (Neo Galaxy-Eyes Tachyon Dragon, Galaxy-Eyes Cipher X Dragon, Number 62, Full Armor Photon Dragon); Galaxy-Eyes Tachyon Primal and Photon Emperor pressure once a LIGHT Dragon Xyz is on the field
• Turn 1 (going first): Normal Summon Galaxy Soldier or Orbital 7 / Photon Delta Wing to reach a Level 4 or 8 LIGHT body, search Galaxy or Photon, then Xyz Summon a Dragon from the Extra Deck
• Turn 2 (going second): Hand traps (Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Nibiru) to interrupt the opponent's first board, then rebuild through Galaxy searchers into an Extra-Deck Xyz
• Recovery: Galaxy Summoner and Photon Orbital recover Photon or Galaxy monsters from the GY; Galaxy Wizard and Pot of Sloth add cards late
• After siding: Not evaluable: the deck runs zero Side Deck cards, so there is no defined post-side plan

Why it scores here

The deck reliably opens a LIGHT starter: its searchers (about 83% chance of at least one in an opening 5, Inferred) reach Galaxy and Photon Level 4 and 8 bodies that feed Xyz Summons. It converts that into Dragon Xyz boards with 3000 to 4500 ATK and a broad interaction suite (negations, Lightning Storm, Harpie's Feather Duster, Dominus Spark, Illusion Gate, Forbidden Droplet). Its weaknesses are structural: the main deck mixes Galaxy-Eyes, Photon, Seventh, Mulcharmy, Forbidden, Dominus and Cipher pieces, several of which (Mulcharmy Fuwalos, Forbidden Droplet, Dominus Spark) do not connect to the engine. The list is also Illegal (Seventh Tachyon at 3 copies vs 1 allowed, Ash Blossom at 3 vs 2 allowed) and has no Side Deck, so the score is capped at 35 as a theoretical, structural-only read. Popularity was not credited: the archetype usage data confirms the core cards are real, but it does not add points. No card scores were averaged; the deck was scored as a system with no recorded combos, so floor and ceiling are text-based inference.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-4); engine_conflicts (-5); single_extra_deck_choke_point (-3). Final formula: Illegal: uncapped 0.80*Structural(57) + 0.20*TournamentReliability(45) + Modifiers(-12) = 43, capped at 35 as a theoretical/structural-only read; Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · 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

• Broad interaction: 8 hand traps plus negation and removal spells
• Strong Extra-Deck closing power at 4000 to 4500 ATK
• Multiple searchers (16) to reach Galaxy and Photon starters
• Galaxy and Photon LIGHT synergy with Galaxy Soldier, Orbital 7 and Photon Delta Wing

Weaknesses

• Illegal copy counts (Seventh Tachyon 3 vs 1, Ash Blossom 3 vs 2)
• No Side Deck, so zero post-side adaptation
• Several off-engine cards (Mulcharmy Fuwalos, Forbidden Droplet, Dominus Spark, Triple Tactics Thrust)
• Sub-archetype spread without a unifying Tachyon engine

Critical choke points

• Galaxy-Eyes Tachyon Primal (1 copy) as the single Dragon Xyz trigger
• Seventh Tachyon and Rank-Up-Magic chain (illegal count and Limited)
• Galaxy Soldier and Orbital 7 as the only Level 4 and 8 LIGHT starters for the first turn

Recommended changes

Evidence & confidence

• Verified: Copy-limit violations: Seventh Tachyon 3 vs 1 and Ash Blossom 3 vs 2 (Semi-Limited); Main 55 / Extra 14 / Side 0 counts within size_rules; Card text roles and stats for all 40 distinct cards in evidence; Archetype usage inclusion percentages (archetype-level, not this deck)
• Observed: Usage statistics show the Galaxy-Eyes/Photon core is standard for this archetype
• Inferred: Opening-hand consistency from the hypergeometric table; Dimension scores D1 to D14 and structural and going-first/second estimates; Negation and removal semantics read from card text
• Provisional: Median combo output (no recorded boards); Matchup and format fit (no tournament or dated meta); Meta Power (null)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry exists in YGOVN Usage-stat mismatch: usage_statistics marks nine Extra-Deck core cards (including Number 107, Number 38, Dragluxion, GE Full Armor, GE Cipher Dragon, GE Cipher Blade, Galaxy Photon Dragon, GE Solflare, Number 62, Number C62) as not in this deck, but the cards list runs them; core_present_pct 38.9 is untrusted and the cards list was used (17 of 18 core present, only Number 90 missing) Side Deck empty: no post-side evidence possible Meta Power is Provisional unless a dated metagame sample is supplied
