Tachyon Deck #660739 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±7 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Rank 8 Dragon Xyz toolbox
• Format: duel-links

Legality

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

Identity & game plan

• Win condition: Two Level 8 LIGHT/DARK Dragons into a Rank 8 toolbox, led by Number 107: Galaxy-Eyes Tachyon Dragon upgraded into Number C107: Neo Galaxy-Eyes Tachyon Dragon (4500 ATK, negates all other face-up cards and blocks field activation), backed by Number 38: Hope Harbinger Dragon Titanic Galaxy for Spell negation.; Strip the opponent's board with Forbidden Droplet / Book of Eclipse / Nibiru / Infinite Impermanence, then swing for lethal with Number 62: Galaxy-Eyes Prime Photon Dragon or Galaxy-Eyes Cipher Blade Dragon.
• Turn 1 (going first): Resolve Schwarzschild Infinity Dragon (or the archetype skill) to place two Level 8 LIGHT/DARK Dragons, Xyz into Number 107 or Divine Golden Shadow Dragon Dragluxion, layer Number 38 plus a set/hand-held Tachyon Transmigration and Tachyon Spiral Galaxy, and hold Impermanence/Ghost Mourner as follow-up interaction.
• Turn 2 (going second): Open with a board breaker from the 15-card non-engine package, then rebuild with Schwarzschild into a Rank 8 and convert the cleared board into battle damage with Prime Photon or Cipher Blade's destroy effect.
• Recovery: Return bodies with Galactic Spiral Dragon and Nebula Dragon's GY banishes, recover a Rank 8 via Galaxy Satellite Dragon / Galaxy-Eyes Full Armor Photon Dragon overlays, and use Rank-Up-Magic - The Seventh One for a free Number 101-107 when it is drawn for turn.
• After siding: This export carries no Side Deck (0 cards) and Duel Links ladder play in this context has no between-game siding, so adaptation is limited to main-deck ratio shifts among the hand-trap and board-breaker slots.

Why it scores here

Tachyon is scored as a compact, skill-assisted Rank 8 Dragon combo shell whose identity comes from a small engine wrapped in an unusually large non-engine package, not from the sum of its card scores. Its consistency rests on Schwarzschild Infinity Dragon plus the Level 8 LIGHT/DARK Dragon pool: a five-copy starter pool reaches a live body roughly 63% of the time in an opening five (Inferred), while the 16-copy archetype cluster makes some Galaxy/Tachyon piece near-certain. Conversion had to be inferred from card text because this export records zero parseable combo boards: the text supports Schwarzschild into two Level 8 bodies, Number 107 or Dragluxion, then Number 38 plus Tachyon Transmigration, with Number C107 as the ceiling — but the realistic median is one Rank 8 and a single interaction piece. Half the deck (15/30) is Forbidden Droplet, Book of Eclipse, Nibiru, Infinite Impermanence and Ghost Mourner, which makes the going-second plan its strongest single quality while leaving the engine thin and dependent on one primary starter. Nothing here was credited for Tachyon's popularity or the guides' tier claims, and no individual card power score was averaged into the total — the score reflects consistency, median output, interaction layering, resilience and cost measured on the system.

Dimension scores

How the score was computed

Strategy profile: 70% Combo / 30% Midrange. Structural ≈ 65, Going First ≈ 66, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Heavy non-engine density (-2); Hard-garnet / conditional singleton burden (-2); Banlist exposure (-1); Compact, skill-assisted archetype core (1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.63 · key two-card combo ≈ 0.13 · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense, redundant interaction package: 15 of 30 Main Deck slots are hand traps or board breakers, giving a strong going-second profile.
• Compact engine shell that converts two Level 8 LIGHT/DARK Dragons into a genuine Rank 8 toolbox with Number 107, Dragluxion, Number 38 and Number C107.
• Layered end-board interaction across monster negation, Spell negation, a Counter Trap and battle-phase effect suppression.
• High closing damage: Number C107 at 4500 ATK, Number 62 up to 4000+, Cipher Blade at 3200 with targeted destruction.
• All nine Extra Deck slots are purposeful, and secondary summoning routes (Full Armor Photon, Dragluxion) recycle Rank 8 bodies.

Weaknesses

• Engine consistency funnels through Schwarzschild Infinity Dragon and the Level 8 Dragon pool; only five cards function as genuine primary starters.
• Nine singleton engine cards produce high variance and several conditional dead cards in the opening hand (Rank-Up-Magic - The Seventh One, Chaos Dragon Levianeer, Nebula Dragon without a partner).
• No recorded combo data means the real floor and ceiling are unverified; the deck's power is a text-based projection.
• No Side Deck and no post-side plan, so best-of-three adaptation is essentially absent.
• Half the deck is non-engine, meaning hands can be interaction-heavy with no way to build a board.

Critical choke points

• Schwarzschild Infinity Dragon resolving — if it is negated, the deck has very few independent routes to two Level 8 bodies.
• The Rank 8 Xyz summon itself: Ash-style or effect negation on the overlayed boss strands two materials on board.
• Tachyon Transmigration requires a Galaxy-Eyes monster already on field, so it is dead when the board is broken before it is set.
• Limited card ceilings (Seventh Tachyon, Tachyon Transmigration, Dragluxion at one copy each) mean no redundancy for those specific effects.

Evidence & confidence

• Verified: Legality: 30 Main / 9 Extra / 0 Side against Duel Links size rules (20-30 / 0-9 / 0-9), no violations, no size warnings.; Restricted cards: Divine Golden Shadow Dragon Dragluxion, Seventh Tachyon and Tachyon Transmigration are Limited and each run at exactly one legal copy.; Card text is present and resolved for all 22 distinct cards across Main and Extra Deck.; CardUsageStat: 18 stat rows with a 50% core threshold; the list includes 10 of the 18 flagged core entries.; Four archetype guides are attached to the Tachyon archetype.
• Observed: Zero parseable combo boards were recorded for this deck (total_combos 0, scored_combos 0), so no board power, starter frequency or interaction density was measured.; Preprocessor counts 30 Main / 9 Extra / 0 Side and a copy histogram of 7 three-ofs plus 9 singletons.
• Inferred: P(≥1 primary starter in an opening five) ≈ 0.63 from the 5-copy starter pool; the 16-copy archetype cluster figure of 0.986 is not a starter rate.; Estimated full-brick rate around 8% based on singleton conditional cards and the 15-card non-engine split.; Median output projected as one Rank 8 plus a single interaction piece; ceiling projected as Number 107/Dragluxion into Number 38 + Tachyon Transmigration + Number C107.; Going-second strength derived from the count and text of Forbidden Droplet, Book of Eclipse, Nibiru, Infinite Impermanence and Ghost Mourner.
• Provisional: Meta Power is null — no dated metagame sample was supplied.; Matchup Coverage (D13) is provisional; the guides' claims that Tachyon leads the 2026 Duel Links format are commentary, not a dated sample.; Side Deck Adaptability (D12) is provisional because the export has no Side Deck and no post-side performance data.
• 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 are absent. No win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates); those signals are Inferred or Unknown. Meta Power stays Provisional because no dated metagame sample was supplied. Usage-stat 'in_this_deck' flags conflict with the resolved card list for Number 107, Number 38, Number C107, Dragluxion, Full Armor Photon and Cipher Blade; the resolved card list was treated as source of truth. No Side Deck cards and no post-side data, so D12 is structurally unmeasurable.
