Tachyon Deck #773347 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 26/100 (±8 · Confidence: Medium)

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

Legality

Main 45 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Psychic End Punisher, Dark Magician of Destruction, Master of Chaos, Dragluxion, Red-Eyes Black Dragon Exceed) reached through a mixed set of Fusion, Synchro, Xyz and Link summons; the list has no recorded line that shows which one actually wins; Ecclesia and the Dark Dragon and Gravity Controller supported by Shining Sarcophagus and Gandora-G
• Turn 1 (going first): Open with Dark Magician Girl, Mulcharmy Purulia, Pot of Sloth or Shining Sarcophagus to search and draw; the list does not show a single reliable starter line
• Turn 2 (going second): Use the hand traps Ash Blossom and Ghost Ogre, Maxx C, and Harpie's Feather Duster or Lightning Storm to interrupt the opponent's board before a Fusion or Xyz play
• Recovery: Recursion through Dark Time Wizard, Mulcharmy Purulia and Gandora-G banishing, with few resources left after a hand-trap interruption
• After siding: None: the deck runs no side deck, so there is no adaptation plan against any matchup

Why it scores here

The deck reliably has a searcher-driven opening: about 73 percent of opening hands in 5 cards contain at least one searcher-text card (Inferred from the hypergeometric estimate), and the 3-copy staples support that. Interaction is the deck's strongest layer, with 4 hand traps, 7 negation-text cards and 14 removal-text cards giving it several ways to answer a board. The engine itself is weak: only 3 of 16 usage-core Tachyon cards are present, the core Galaxy-Eyes Tachyon Dragon is absent, and exact-name archetype purity is 0 percent, so the Extra Deck is a mix of unrelated bosses rather than one coherent system. No combos were recorded, so the ceiling and median come from text only and are scored low. The Forbidden Albion the Branded Dragon makes the list illegal and caps the score; the deck also has no side, which removes any post-side adaptation. The score comes from consistency, interaction and the Extra Deck on the system, not from the Tachyon archetype's popularity and not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Balanced (default; strategy is mixed Toolbox/Midrange). Structural ≈ 40, Going First ≈ 38, Going Second ≈ 35, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist_exposure (-6); no_side_deck (-3); engine_incoherence (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 38, then Illegal cap via modifiers to 26

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.73 · 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

• Searcher density (10 cards) gives a likely opening starter
• Four hand traps and seven negation-text cards give layered interaction
• Copy histogram is tidy with 3-copy staples

Weaknesses

• Forbidden Albion the Branded Dragon makes the deck illegal
• Core engine incomplete: 3 of 16 usage-core Tachyon cards present
• No side deck and no post-side plan
• No recorded combos, so the ceiling and median are unverified

Critical choke points

• Albion the Branded Dragon (Forbidden) must be removed before the deck can be played
• Searcher-text cards are the only route to the Extra Deck bosses

Recommended changes

Evidence & confidence

• Verified: Main 45, Extra 15, Side 0 within format size rules; Albion the Branded Dragon is Forbidden and run 1 copy; Harpie's Feather Duster, Maxx C and S:P Little Knight run at their Limited cap of 1; Ash Blossom and The Fallen and The Virtuous run at Semi-Limited cap of 2; Usage-core presence 3 of 16 (18.8 percent)
• Inferred: Searcher opening probability about 0.73; Consistency and brick estimates from composition; Interaction density from card text
• Provisional: Meta power and matchup fit: no dated metagame sample
• 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 in YGOVN: going-first and going-second splits are unknown Meta Power is provisional unless a dated metagame sample is supplied Deck title is null, so the intended build name is unknown
