Crystron Deck #756159 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Crystron Synchro/Xyz board pressure (Crystron Eleskeletus, Superdreadnought Rail Cannon Gustav Rocket) backed by Train and K9 extenders; Cyber Dragon Nova/Infinity tempo and Train Xyz payoffs, if the Extra Deck lines are reachable
• Turn 1 (going first): Search and summon through Crystron Inclusion, Night Train Blue Traveler and Exceptional Schedule, then hold Ash Blossom and Droll-style interaction; no verified starter sequence exists in the evidence
• Turn 2 (going second): Hand traps (Ash Blossom, Droll & Lock Bird, Forbidden Droplet) plus K9-17 Izuna or K9-66a Jokul to answer the opponent's board, then a Crystron or Train Xyz/Synchro line
• Recovery: Crystron Tristaros and Crystron Cluster recursion, plus Crystron Inclusion from GY banish, to rebuild the Crystron board after a single interruption (Inferred)
• After siding: Not assessable: the deck has zero side-deck cards, so there is no post-side plan

Why it scores here

The deck is Illegal in OCG as built: three copies of two Semi-Limited cards, two copies of a Limited card, and three Forbidden cards (Called by the Grave, Triple Tactics Talent, F.A. Dawn Dragster), so it is capped low and scored as a structural read only. Structurally it has a reasonable spine: about 67% of the 8 archetype-core copies are open in a 5-card hand, and a searcher-heavy main (18 searcher-text cards) gives roughly 95% odds of at least one searcher. The weakness is coherence: exact Crystron purity is only 11 of 57 archetype-relevant cards, the rest is split across Train, K9, Cyber Dragon, Therion, Qli, Infinitrack and F.A., and no combo boards exist to show the engines actually connect. Popularity and archetype usage stats were not used to raise the score, and card scores were not averaged; the final number is driven by the system-level dimensions above, the illegality cap, and banlist and no-side-deck modifiers.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Toolbox secondary; Midrange weights used for scoring. Structural ≈ 43, Going First ≈ 40, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-6); no_side_deck (-3); archetype_purity (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*43 + 0.20*35 = 41.4, then modifiers -11 = 30; capped low for Illegal status

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

• Searcher density (18 searcher-text cards, P ≈ 0.95 for at least one in opening hand)
• Multiple Extra Deck routes (Xyz, Link, Synchro) with several high-ATK finishers
• Hand-trap and negation coverage for going second (5 hand traps, 9 negation-text cards)
• Recursion through Crystron Tristaros and Crystron Cluster

Weaknesses

• Illegal as built: over-limit Ash Blossom, K9-17 Izuna and Droll & Lock Bird, plus three Forbidden cards
• Low archetype coherence: exact-name purity 19.3%, with six sub-engines
• No side deck
• No recorded combos, so no measured floor, median or ceiling
• High brick risk from 16 singletons and tech slots

Critical choke points

• Crystron Inclusion and the Crystron Synchro/Xyz line both need Crystron cards that are only 11 copies total
• Gustav Max (Limited, 1 copy) is the only route to Gustav Rocket in several lines
• Cyber Dragon Nova/Infinity and K9 extenders are missing from the list, so their Extra Deck summons are not reliably reachable

Recommended changes

Evidence & confidence

• Verified: Illegal status: over-limit Ash Blossom, K9-17 Izuna and Droll & Lock Bird; Forbidden Called by the Grave, Triple Tactics Talent, F.A. Dawn Dragster; Main 42 and Extra 15 are within size rules; zero side cards; Archetype purity 19.3% and spread across Train, Crystron, K9 and others; Card text for the listed hand traps and Extra Deck finishers
• Observed: Usage stats show Crystron Inclusion and Crystron Cluster at 85%+ inclusion, but this is context only
• Inferred: Opening-hand starter and core probabilities (hypergeometric); Brick and dead-card risk from off-archetype copies; Going-second hand-trap coverage; Recovery plan via Tristaros and Cluster recursion
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament context)
• 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 — brick, starter and matchup rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck supplied, so post-side performance is unknowable
