Tachyon Deck #763568 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 31/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Combo
• Format: ocg

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra-Deck Dragon boss monsters (Galaxy-Eyes / Light and Darkness Dragon / Red-Eyes Darkness Metal Dragon) reached through Dragon-search and draw chains; Fusion, Xyz and Synchro boards built from Dragon-type materials
• Turn 1 (going first): Search and summon Dragons through Bystial/Tachyon/Branded starters, then reach a Dragon Extra-Deck boss; the Illegal copy counts make this plan theoretical only
• Turn 2 (going second): Use Forbidden Chalice/Lance and Tachyon Transmigration style interaction (no hand traps in the list) to slow the opponent, then Dragon extension
• Recovery: Recur Dragon monsters from the GY through Branded Regained, Bystial Saronir and Galaxy-Eyes Tachyon Primal; no quantified recovery data exists
• After siding: Not available: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

The deck opens a functional plan at a moderate rate: about 67% of hands contain at least one of its 11 searcher-text cards, and it runs a Dragon-dense main deck (39 Dragon-race cards) that supports Dragon Extra-Deck bosses. Conversion and floor are not measured: no parseable boards exist, so the combo scores rest on the card text alone. Interaction is present as removal and negation text but the list has no hand traps, and the going-second plan is weak. The Side Deck is empty, so adaptability is scored as its lowest value. Popularity and archetype usage were not counted as power: only 1 of 18 core archetype cards is in the list. The legality cap applies, so the Final score is a structural-only read; card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 45, Going First ≈ 40, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Illegal cap applied: 0.8*45 + 0.2*35 = 43, minus 12 = 31)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.67 · 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

• Dense Dragon typing (39 Main Deck Dragons) supports several Extra-Deck bosses
• Searcher-text density (11 cards) gives about 67% at-least-one access in a 5-card hand
• Extra Deck is well spread across four summon types without one dependency

Weaknesses

• Illegal list: Forbidden Amorphage Goliath and two Limited cards run above their limit
• Only 1 of 18 archetype core cards is present, so the deck is not the archetype-standard build
• No hand traps, no floodgates and no Side Deck

Critical choke points

• Galaxy-Eyes Tachyon Primal is the only archetype core card; losing it removes the Galaxy-Eyes route
• Bystial/Dragon starters rely on single-copy Limited cards that cannot be legally run at this count

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, Amorphage Goliath Forbidden at 1 copy; Allure of Darkness and The Bystial Lubellion over limit; Main 57 and Extra 15 are inside the OCG size rules; Side 0 is legal; No hand traps, no floodgates, no Side Deck; Archetype core present 1 of 18 (5.6%)
• Observed: No recorded boards; combo evidence is empty
• Inferred: Opening-hand access ≈ 0.67 for the searcher group (hypergeometric, Main only); Structural profile scores on D1–D14; Going-first and going-second estimates
• Provisional: Meta power (null) and matchup fit (D13) need a dated metagame sample
• 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 (going-first/second, matchup, brick/starter/OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck in the list, so post-side scoring is absent
