Galaxy Tachyon Deck #487578 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Control, Xyz
• Format: master-duel

Legality

Main 42 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Level-8 Dragon Xyz beatdown (Galaxy-Eyes Cipher X 4000 ATK, Full Armor Photon 4000 ATK, Number 107 3000 ATK) after hand traps protect the starter; Number 107 once-per-battle negate-and-reset of the opponent's field, then attack
• Turn 1 (going first): Open a Dragon/Seventh starter (Seyfert, Schwarzschild, Dragon's Light and Darkness), Xyz into a 3000+ ATK boss while holding Ash/Veiler/Impermanence for the opponent's turn
• Turn 2 (going second): Keep 2-3 interaction cards (Ash, Veiler, Impermanence, Nibiru) to answer the opponent's first summon, then convert with an Xyz on a later turn
• Recovery: Rebuild through GY/banish recursion (Magnamhut, Lubellion, Galaxy-Eyes Tachyon Primal) and searchers (Seyfert, Lubellion, Dragon's Light and Darkness)
• After siding: No side deck is registered (Side Deck size 0), so no post-side plan is evaluated; the list must be resilient on its own

Why it scores here

The deck is scored as a connected Midrange system, not as an average of its cards. Its three-copy searchers and Dragon starters (Seventh Tachyon, Starliege Seyfert, Schwarzschild) give roughly an 88% chance of at least one searcher in a 5-card opening hand, so it usually reaches a live line, though the engine itself is split across Galaxy-Eyes, Seventh and Bystial pieces (57 off-archetype copies). Interaction is the strongest feature: 10 hand traps and 19 negation-text cards, with an estimated 83% chance of at least one hand trap in a going-second 6-card hand, and Number 107 can reset the opponent's board once per Battle Phase. Conversion is credible (Level-8 Xyz at 3000-4000 ATK) but there are no recorded boards, so the ceiling and median are text-only inference and are scored conservatively. Popularity and archetype share did not earn points; no tournament or win-rate data exists for this list, so meta-fit stays provisional, and the empty side deck and single-copy Xyz spread cap the score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.6, Going First ≈ 56, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: engine conflicts (-3); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*61.6 + 0.20*58 = 60.9, then modifiers -4 = 57

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.72 · 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

• Ten hand traps and 19 negation-text cards give layered, redundant interaction
• Three-copy Ash, Veiler and Impermanence keep the interaction redundant across turns
• Level-8 Xyz finishers at 3000-4000 ATK provide closing power
• Searcher density (14 text hits) supports consistency

Weaknesses

• Engine is split across three sub-archetypes with 57 off-archetype copies
• Core archetype staples absent: usage stats list Mitsurugi, Dominus Spark, Eternal Galaxy and Galaxy Photon Dragon at 100% inclusion but none are in this list
• No side deck, so no post-side adjustment is possible
• Many single-copy slots raise brick and dead-card risk

Critical choke points

• Number 107 is the only 101-107 Number in the Extra Deck, so Seventh Tachyon's search has one target
• Going-second hands depend on hand traps; a hand with none of them has no early interaction
• Level-8 Xyz plan requires specific Level-8 Dragon materials

Recommended changes

Evidence & confidence

• Verified: Main 42 / Extra 15 / Side 0 within Master Duel size rules; All restricted cards at legal copy limits (Bystial Magnamhut 1, Harpie's Feather Duster 1); Composition, copy histogram and role-tag counts
• Inferred: Hypergeometric starter, searcher and hand-trap probabilities; Interaction density and negation semantics from card text; Going-first and going-second estimates
• Provisional: Meta power and matchup fit (no dated meta sample); Side-deck adaptability (no side deck registered)
• Data gaps: No recorded combos; floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second or matchups Usage-statistics in this deck flags contradict the card list (e.g. Number 107, card ID 88177324, is listed in the deck with 2 copies but flagged in this deck=false), so core-card presence=12 is unreliable No side deck registered
