Crystron Deck #769826 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Medium)

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

Legality

Main 53 / Extra 14 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Crystron Eleskeletus, K9-X Werewolf, Number C101, Perfectron Hydradrive Dragon) reached through Tuner-based Synchro and Xyz summons; Link and Xyz boards that use hand-trap and negation interaction to keep the board alive
• Turn 1 (going first): Open a Crystron or K9 Tuner or searcher, use Crystron Inclusion or Mulcharmy Fuwalos for board presence, then Synchro or Xyz into an Extra Deck boss
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Snow Rabbit, Ghost Belle, Droll and Maxx C to stop the opponent's first engine, then rebuild through K9 summons
• Recovery: Recur Crystron and K9 monsters from the GY with Crystron Sulfefnir, K9-66b Lantern and K9-17 Ripper; search with Crystron Inclusion and A Case for K9
• After siding: Not applicable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

This list is Illegal in OCG: it runs three copies of the Forbidden K9-04 Noroi, one copy each of the Forbidden Artifact Mjollnir and F.A. Dawn Dragster, and three copies of the Limited A Case for K9 against a limit of one, so it does not receive a normal Final Contextual score and is capped as a theoretical, structural-only read. Structurally the deck reliably opens a searcher or Tuner and reaches Extra Deck bosses through Synchro and Xyz summons, with Crystron Inclusion present in 26% of five-card openings and at least one searcher in 70%. Its strongest dimension is interaction: nine hand traps and several negate or removal effects give it real going-second answers, with a hand trap in 69% of six-card going-second hands. The weaknesses are brick risk and a diffuse main deck: only 12 of 53 main cards carry the exact Crystron name, zero-level spells and traps and off-theme tech cards make hands dead, and the deck has no Side Deck to adapt. Meta position and popularity earned no points, the score was not averaged from card scores, and no combo, tournament or win-rate data supports the ceiling.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 46, Going First ≈ 40, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist_exposure (-6); no_side_deck (-3); unresolved_passcode (-1). Final formula: No reliable metagame: 0.80*Structural(46) + 0.20*TournamentReliability(30) + ContextModifiers(-10) = 32.9; capped at 25 because the list is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.26 · 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 interaction (9 hand traps, 8 negate-text cards) gives strong going-second answers
• Multiple searchers and recursion routes (11 searcher-text cards) support consistent access to the Crystron and K9 engine
• Extra Deck bosses include high-ATK and multi-attack threats

Weaknesses

• Illegal list: Forbidden cards and an over-limit Limited card
• Low exact-archetype purity (17.9%), with 55 off-archetype copies
• No Side Deck, so no post-side adaptation
• Zero-level spells and traps and tech cards create dead-card risk

Critical choke points

• Crystron Inclusion and the searcher package are the main engine access, and each is a single-copy or small-count route
• Without a Crystron or K9 Tuner or Synchro route, Extra Deck bosses do not come online

Recommended changes

Evidence & confidence

• Verified: Illegal status: Forbidden K9-04 Noroi (3), Artifact Mjollnir (1), F.A. Dawn Dragster (1) and Limited A Case for K9 (3 vs 1); Main 53 and Extra 14 are within the OCG size rules; Exact-name archetype purity 17.9%; No Side Deck (side count 0)
• Inferred: Opening-hand probabilities for Crystron Inclusion and the searcher package; Brick and dead-card risk from zero-level spells and tech cards; Going-second hand-trap coverage (69%); Interaction density and resilience read from card text
• Provisional: Meta Power is null; matchup and format fit (D13) are Provisional with 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 pilot match record absent Passcode 10443957 could not be resolved and is counted as main No win-rate telemetry exists in YGOVN, so matchup and going-first/second rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck has no Side Deck, so D12 has no post-side evidence
