Tachyon Deck #770404 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 65/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Stun, Midrange
• Format: duel-links

Legality

Main 30 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz Summon a Galaxy-Eyes / Tachyon Dragon (Number 107 or Neo C107) from hand-started Level 8 and Level 4 dragons, then close with a 3000-4500 ATK boss; Galaxy-Eyes Full Armor Photon Dragon (4000 ATK) or Galaxy-Eyes Cipher Blade Dragon (3200 ATK) once the board is already established
• Turn 1 (going first): Hand-start a Level 8 dragon (Schwarzschild Infinity Dragon, Galaxy-Eyes Tachyon Primal) or Tachyon Cloudragon, build a Level 8 pair, and Xyz Summon Number 107 while holding Effect Veiler or Droll & Lock Bird for the opponent's first activation
• Turn 2 (going second): Use the hand traps (Effect Veiler, Droll & Lock Bird, Infinite Impermanence, Nibiru) to strip the opponent's first board, then Xyz into a negate boss (Neo C107 or Number 107) to reset their monsters
• Recovery: Banish Nebula Dragon or Starliege Seyfert from the GY to continue the Dragon chain, and rebuild material with Galactic Spiral Dragon and Schwarzschild Infinity Dragon re-summons
• After siding: Not applicable: Duel Links has no side deck in this format, so the side count is 0 and there is no post-side adjustment

Why it scores here

The deck reliably opens into a functional plan because seven copies of hand-start Level 8 and Level 4 dragons (Schwarzschild Infinity Dragon x3, Galaxy-Eyes Tachyon Primal x2, Tachyon Cloudragon x2) give a P(at least one in the opening 5) of about 0.76 and in the opening 6 of about 0.83 (Inferred), and the seven hand-trap copies reach about 0.83 going second. It converts that plan into pressure through a deep Extra Deck of Xyz bosses, with Neo Galaxy-Eyes Tachyon Dragon at 4500 ATK and Full Armor Photon Dragon at 4000 ATK as the closers, and its negation text (Number 107, Neo C107, Schwarzschild, Nebula Dragon) gives it real interaction on the system. Its ceiling is evident from the text, but no recorded boards exist, so floor and median remain unmeasured. The score comes from consistency, interaction and closing power of the connected system, not from the Tachyon archetype's popularity, and the individual card scores were never averaged; guide snippets calling the deck strong are context only, not a win rate.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 67, Going First ≈ 68, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: dead or conflicting slots (-2); engine redundancy (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional): 0.80*66.76 + 0.20*58 = 65.0

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.76 · 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

• Seven hand-start dragon copies give a high chance of a functional starter in the opening hand
• Layered interaction: 7 hand traps and 15 negation-text cards, plus field-wide negation from Number 107 and Neo C107
• Strong closers: Neo C107 (4500 ATK), Full Armor Photon (4000 ATK), Cipher Blade (3200 ATK)
• Extra Deck covers several Xyz routes and a Dragluxion searcher

Weaknesses

• Sauravis is dead without Sprite's Blessing, which is not in the deck
• Non-Fusion Area has no target in this list and is a dead slot
• Many one-of tech slots (Numbers Protection, Powersink Stone, Lord of the Tachyon Galaxy, Tachyon Chaos Hole) lower coherence
• No side deck in Duel Links, so there is no post-side adaptation

Critical choke points

• The opening needs one of 7 Level 8/Level 4 hand starters; if none is drawn, the Xyz line does not start
• Number 107 needs two Level 8 monsters on the field, and Level 8 monsters in the main deck total 8, so Xyz summons depend on hand starters surviving disruption

Recommended changes

Evidence & confidence

• Verified: Legal in Duel Links: 30 Main (range 20-30), 9 Extra (range 0-9), 0 Side; Dragluxion is Limited at 1 copy and runs 1 copy, within the legal limit; Neo C107 4500 ATK, Full Armor Photon 4000 ATK, Cipher Blade 3200 ATK, Number 107 and Levianeer 3000 ATK from card data; Extra Deck is 8 Xyz plus 1 Link, per extra_deck_breakdown
• Observed: No recorded boards exist for this deck (combos_evidence total 0)
• Inferred: Opening-hand starter probability about 0.76 (5 cards) and 0.83 (6 cards) from 7 hand-start copies; Negation/interaction density is high from card text; Sauravis and Non-Fusion Area are dead slots in this list; Going-second hand-trap coverage about 0.83
• Provisional: Meta and format fit (no dated metagame 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 match record absent no win-rate telemetry exists in YGOVN: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics join appears wrong for the Extra Deck: Number 107, Galaxy-Eyes Cipher Blade, Full Armor Photon, Number 38, Neo C107, Cipher Dragon and Dragluxion are listed in cards[] (zone extra) but flagged in_this_deck=false, so the missing_core list and core_present_pct (47.8) are unreliable for the Extra Deck Sprite's Blessing (the Ritual Spell that Sauravis needs) is absent from the deck no side deck exists in Duel Links, so post-side evidence is absent by format
