Crystron Deck #768007 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 41 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Crystron and K9 Synchro/Xyz boards (Crystron Quariongandrax, K9-X Werewolf, K9-66X Jacks) built off Crystron Inclusion and Crystron searchers; Divine Arsenal AA-ZEUS and Super Starslayer TY-PHON as late Extra Deck top-ends, reachable only if the engine survives
• Turn 1 (going first): Turn 1 Crystron Inclusion or Chaotic Elements to search a Level 5 monster, then Crystron Sulfador or K9 monsters into a Synchro or Xyz for board presence
• Turn 2 (going second): Use the hand traps (Ash Blossom x3, Infinite Impermanence, Droll & Lock Bird, Forbidden Droplet) to stop the opponent's first engine, then rebuild through Crystron Tristaros or Crystron Citree
• Recovery: Crystron Inclusion can revive Crystron monsters from the GY, and Crystron Eleskeletus can add a Crystron card from the GY or banishment after Synchro Summon
• After siding: None: the deck runs no side cards, so no post-side plan can be evaluated

Why it scores here

The deck opens a live engine on about 73% of going-first five-card hands (9 core Crystron/K9 copies, hypergeometric, Inferred) and has 13 searcher-text cards, which lifts the resource and redundancy scores. Its interaction is broad: 7 hand traps, 10 negation-text cards and 20 removal-text cards cover both going-first and going-second turns. Its ceiling comes from the Extra Deck top-ends (Quariongandrax, Werewolf, Jacks, ZEUS, Starslayer), but no recorded combo boards exist, so the median and floor are text-only inferences. The deck is Illegal as built: Ash Blossom and K9-17 Izuna each run 3 copies against an OCG limit of 2, so its score is capped at a theoretical, structural-only 30 and it earns no points from popularity or archetype usage. No card scores were averaged; the score reflects the system's consistency, interaction and closing power, reduced by the legality breach, the empty side deck and the unresolved passcode.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-6); no_side_deck (-4); unresolved_passcode (-2). Final formula: Illegal: uncapped 0.80*Structural(56) + 0.20*TournamentReliability(50) + Modifiers(-12) = 43, capped at 30 for theoretical/structural-only evaluation (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.73 · key two-card combo ≈ — · full-brick estimate ≈ 0.27 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core engine is accessible on about 73% of going-first opening hands
• Broad interaction: 7 hand traps, 10 negation-text cards and 20 removal-text cards
• Multiple Extra Deck closers at 2600 to 3300 ATK, including two rank-9 and rank-12 Xyz options
• Searcher density (13 cards) supports consistency and recovery

Weaknesses

• Illegal as built: 2 copy-limit violations (Ash Blossom x3, K9-17 Izuna x3)
• Empty side deck leaves best-of-3 with no adaptation
• Low exact-archetype purity (32.7%) across three sub-archetypes
• No recorded combo data, so median and floor are unverified

Critical choke points

• Crystron Inclusion and the K9 Xyz chain: if the first searcher or starter is answered, the second line depends on GY revival
• Core archetype density (9 copies) leaves about 27% of going-first hands without a live engine

Recommended changes

Evidence & confidence

• Verified: Main count 41 and Extra count 14 are within OCG size rules; Ash Blossom & Joyous Spring and K9-17 Izuna each run 3 copies against OCG limit 2 (Illegal); Usage stats: 50% core present; 5 of 10 core cards in deck
• Inferred: P(at least one core starter in a 5-card hand) ≈ 0.73; Brick proxy ≈ 0.27; Going-second hand-trap coverage ≈ 0.70; Interaction and closing read from card text
• Provisional: Meta Power (no dated metagame sample); Matchup fit and format position
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent One passcode (10443957) could not be resolved to a card No win-rate telemetry exists in YGOVN Meta Power is provisional unless a dated metagame sample is supplied Deck is Illegal, so the final score is a capped, theoretical value
