Tachyon Deck #773981 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Blind-Second / OTK
• Format: duel-links

Legality

Main 27 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Assemble a Rank 8 Xyz through Schwarzschild Infinity Dragon / Dragluxion and close with 3000–4500 ATK Galaxy-Eyes Dragons in a 4000 LP format.; Trade hand traps and traps early, then convert a cleared board with Galaxy-Eyes Full Armor Photon Dragon (4000 ATK) or Number C107 (4500 ATK).
• Turn 1 (going first): Special Summon Schwarzschild Infinity Dragon, summon a Level 8 LIGHT/DARK Dragon from Deck, overlay into Divine Golden Shadow Dragon Dragluxion to search a Galaxy/Tachyon card and upgrade into a Rank 8 Dragon Xyz, backed by Numbers Protection / Tachyon Spiral Galaxy and held hand traps.
• Turn 2 (going second): Break the board with Forbidden Droplet (3) and Nibiru (2), brick the opponent's searches with Droll & Lock Bird, then run the same Rank 8 line plus Full Armor Photon / Number 107 for lethal.
• Recovery: Recur through Galactic Spiral Dragon's GY Special Summon, Starliege Seyfert's GY banish, Tachyon Cloudragon's Deck/GY Tachyon summon, and Tachyon Chaos Hole's Draw-Phase recycle from the GY.
• After siding: No Side Deck is built (0 cards); Duel Links is a best-of-1 environment, so adaptation is limited to the Main Deck's ~4 flex slots and the traps chosen for the expected ladder.

Why it scores here

This is a compact Rank 8 Xyz engine carried by three copies of Schwarzschild Infinity Dragon — the only card that converts a single hand card into a body on its own (P(≥1 in a 5-card hand) ≈ 0.47) — so the deck reliably opens something only in the 55–65% band once conditional pieces are counted. The ceiling is real for a 4000 LP format: Dragluxion searches and upgrades into a Rank 8 Dragon Xyz, and Full Armor Photon (4000) or Number C107 (4500) end games fast, but with no recorded boards the floor and median are inferred to be a single Rank 8 plus one interaction piece. Going second is the stronger half because Forbidden Droplet at three, Nibiru at two, Droll at two and Veiler at three give roughly an 87% chance of at least one hand trap in a six-card hand. The score comes from the system — starter density, median output, interaction breadth and recovery — not from averaging card scores, and not from the archetype's popularity or the enthusiastic guide snippets, neither of which earned any points. Heavy point deductions come from thin route redundancy, roughly ten situational one-offs (The Seventh One, Tachyon Chaos Hole, Lord of the Tachyon Galaxy, Galactic Spiral Dragon, Levianeer) and the absence of any side-deck plan.

Dimension scores

How the score was computed

Strategy profile: 0.7. Structural ≈ 58, Going First ≈ 57, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Banlist exposure (-1); Hard garnet burden (-2); Skill dependence not captured in export (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.47 · key two-card combo ≈ 0.15 · full-brick estimate ≈ 0.18 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Very high closing power for a 4000 LP format: Full Armor Photon Dragon (4000 ATK), Number C107 (4500 ATK), Number 107 (3000 ATK) and Cipher Blade Dragon (3200 ATK).
• Strong hand-trap and breaker suite: Effect Veiler ×3, Nibiru ×2, Droll & Lock Bird ×2 and Forbidden Droplet ×3 — P(≥1 hand trap in a 6-card hand) ≈ 0.87.
• Dragluxion compresses search plus a Rank 8 Dragon upgrade into a single Extra Deck slot, making the two-body Rank 8 line convert into real advantage rather than a vanilla body.
• Layered interaction by card type: Spell negation (Number 38), targeting negation (Heliopolis), a counter trap (Numbers Protection), battle protection (Tachyon Spiral Galaxy) and Number 107's effect negation.
• Genuine recursion exists (Galactic Spiral Dragon from GY, Seyfert's GY banish, Cloudragon's Deck/GY Tachyon summon, Chaos Hole's GY recycle), so the deck is not purely a one-shot combo.

Weaknesses

• Thin starter density: only three copies of a true one-card starter; everything else needs a partner card or an already-built board.
• Around ten conditional or situational slots create a meaningful near-dead-hand share and clash with the small Duel Links opening hand.
• No Side Deck at all — no post-game adaptation plan, purely Main Deck flex slots.
• Dragluxion is Limited to 1, removing redundancy from the single most important Extra Deck card.
• No recorded boards in the evidence pack, so the combo floor and median are unproven rather than measured.
• The summon path for Number C107 is not evidenced by any listed Rank-Up card (The Seventh One only reaches Number 101–107), so the 4500 ATK top end may not be reachable within this list alone.

Critical choke points

• Schwarzschild Infinity Dragon is the only self-contained starter; negating or removing it strands most hands.
• Divine Golden Shadow Dragon Dragluxion at one copy — losing it removes both the search and the Rank 8 upgrade.
• Galaxy-Eyes Tachyon Primal requires a Dragon Xyz already on field, so it cannot initiate a line after a failed starter.
• Chaos Dragon Levianeer requires three LIGHT/DARK monsters in the GY, making it dead in opening hands and dependent on a resolved engine turn.

Evidence & confidence

• Verified: Deck is legal: 27 Main / 9 Extra / 0 Side, no size violations, no copy-limit violations.; Divine Golden Shadow Dragon Dragluxion is Limited (legal copies 1) and is run at exactly 1 copy.; Card texts and stats for all 26 distinct cards (Schwarzschild Infinity Dragon summon-and-negate clause, Dragluxion search/upgrade, Number 38 Spell negate, Numbers Protection counter trap, etc.).; Side Deck count is 0.; combo data contains 0 recorded boards ('no parseable boards').
• Observed: Usage statistics list 18 stat rows with 100% inclusion for Galaxy-Eyes Tachyon Primal, Tachyon Spiral Galaxy, Forbidden Droplet, The Seventh One, Seyfert, Galactic Spiral Dragon, Nebula Dragon, Schwarzschild Infinity Dragon, Droll and Chaos Dragon Levianeer — this list matches the archetype-standard core on 12 of 18 entries.; Four guide topics exist for the archetype with conflicting tone (one calling it dominant in 2026, another calling it weaker than meta).
• Inferred: P(≥1 Schwarzschild Infinity Dragon) ≈ 0.47 in a five-card hand, so live opens are in the 55–65% band counting two-card lines.; Full-brick estimate ≈ 15–20% from the count of situational one-ofs.; Two-card Nebula Dragon line probability ≈ 0.15 (Nebula plus another Level 8 Dragon).; Median output is a single Rank 8 plus one interaction piece; ceiling is Dragluxion into a searched Rank 8 Dragon.; Going-second power is meaningfully higher than going-first power given Droplet ×3 and a 0.87 chance of a hand trap in six.
• Provisional: Meta Power is null: no dated metagame sample was supplied.; Matchup coverage and format fit cannot be scored without tournament data.; Impact of the Duel Links skill ('Tachyon Dragon Domination' per guides) is unknown from this export.; Whether Number C107 is reachable in this exact list (no listed Rank-Up enabler reaches it).
• Data gaps: No combos supplied — combo floor/median/ceiling is 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, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown. Meta Power is Provisional unless a dated metagame sample is supplied. Duel Links skill is not part of the deck export, although guide evidence indicates the archetype leans on one. Supplied draw probabilities assume 5-card (first) and 6-card (second) hands, which overstates starter odds versus Duel Links' real opening hand size.
