Tachyon Deck #758873 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 42 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Exosister Xyz pressure (Exosisters Magnifica, Karmael, Kaspitell, Mikailis) built from Exosister starters, with Tachyon/Seventh support; Super Starslayer TY-PHON and Divine Arsenal AA-ZEUS as single-copy Extra Deck finishers
• Turn 1 (going first): Open an Exosister starter (Elis, Martha, Stella) or a searcher (Betrayal, Sophia, Irene) and make a Xyz with two Level 4 Exosisters, using hand traps to protect the line
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Maxx C, Infinite Impermanence) to break the opponent's starter and then convert through Exosister Xyz
• Recovery: Recover through Exosister searchers (Betrayal, Pax, Sophia) and Xyz materials kept in the GY and Extra Deck; no recursion verified in the evidence
• After siding: Not evaluable: the deck has no Side Deck (0 cards)

Why it scores here

The deck reliably opens a starter about one time in three from a 5-card hand (three copies of Exosister Elis, Martha, and Pax each give about 0.32), and a searcher is present in about 86% of openings. Its engine is Exosister Xyz summoning, which is redundant across several starters, so interruption resilience is moderate. Interaction is the strongest part: nine hand traps and about twelve negation-text cards give a dense, layered end-board defense, and the Extra Deck carries several 2300-2800 ATK Xyz finishers. The score is held down by the absence of combo recordings, so the ceiling and median are text-only inference, by a Forbidden card in the Main Deck that makes the list illegal, by an empty Side Deck, and by 800 LP costs on several engine cards. Popularity and archetype usage did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Toolbox secondary, disclosed as a blend; scored against the Midrange weights. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); no side deck (-3). Final formula: 0.80*Structural(54) + 0.20*TournamentReliability(45) + ContextModifiers(-9) = 43, then capped to 25 because the deck is Illegal (Dimension Shifter over the Forbidden limit); theoretical/structural-only, Meta null (Provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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 hand-trap and negation coverage (9 hand traps, about 12 negation-text cards)
• Strong Xyz finishers at 2300-2800 ATK with redundant Exosister starters
• Searcher density (13 searcher-text cards) gives reliable access to the engine

Weaknesses

• Illegal in OCG: Dimension Shifter is Forbidden and run in the Main Deck
• No Side Deck, so no post-side adaptability
• No combo recordings or win-rate telemetry, so floor and median are unmeasured
• 800 LP costs on several engine cards slow the line and drain resources

Critical choke points

• Exosister Elis, Martha, and Stella: each is about 0.32 or less to be in hand, so the early engine depends on which of them is drawn
• Hand traps as the only protection against a going-second starter

Recommended changes

Evidence & confidence

• Verified: Legality: Dimension Shifter (Forbidden) is run 1 copy with 0 legal copies; the deck is otherwise within the copy limits and size rules; Main 42, Extra 15, Side 0 counts; Extra Deck: 15 Xyz monsters (Magnifica 2800 x2, Karmael 2600 x2, Mikailis 2500, Kaspitell 2300, Zeus 3000, TY-PHON 2900)
• Inferred: Starter and searcher access from hypergeometric odds (0.32 per starter copy-3, 0.86 searcher group); Hand-trap coverage: about 0.79 chance of at least one hand trap in a 6-card going-second hand; Interaction density from card text (nine hand traps, about twelve negation cards); Dimension scores D1-D11 and D14 from card text and composition
• Provisional: Meta Power is null: no dated metagame sample supplied; D13 matchup and format fit: no tournament link or meta-share
• Data gaps: No combos supplied, so combo floor, median, and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry (going-first, going-second, matchup, brick, starter, OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck is Illegal (Dimension Shifter), so the score is capped and labeled theoretical/structural-only
