Crystron Deck #774971 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz and Link beatdown from the Crystron/K9 Extra Deck (K9-X Werewolf, K9-66X Jacks, Crystron Eleskeletus, Divine Arsenal AA-ZEUS) after hand traps clear the opponent's interaction; Recursion-driven Crystron Synchro and Link chains through Crystron Tristaros and Crystron Sulfador
• Turn 1 (going first): Open with a Normal Summon of K9-17 Izuna or K9-66b Lantern (the deck runs 12 Level-5 K9 and Crystron bodies), search with Crystron Inclusion or A Case for K9, then build an Xyz or Link from the Extra Deck
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Infinite Impermanence to answer the opponent's first engine activation, then rebuild the board with Crystron recursion
• Recovery: Recover through Crystron Sulfefnir and Crystron Sulfador GY effects plus Crystron Inclusion banish-revival, then reload with Mulcharmy draw effects
• After siding: Not evaluable: the deck runs an empty Side Deck (0 cards), so no post-side plan exists

Why it scores here

The list reliably opens a Crystron or K9 starter in the opening hand (P(at least one archetype-core card in a 5-card hand) is about 0.96, Inferred), and the 14 negation-text cards and 12 hand-trap cards give it real interaction density on the going-second side. Its ceiling is limited by a split engine: only 11 of 56 Main Deck cards are named Crystron, with substantial K9, Mulcharmy and generic tech slots, and no recorded combos exist to confirm conversion. The deck has no Side Deck at all, which drops adaptability and tournament reliability, and it runs more copies of Semi-Limited cards than the OCG limit allows. Under the rubric it is an illegal list, so the score is capped at 30 and the result is theoretical and structural only; popularity of the Crystron archetype did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-3); no_side_deck (-2); illegal_copy_limit_cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*53 + 0.20*40 = 50.4; context modifiers total -5 gives 45.4; Illegal copy-limit cap applies, so the final score is 30 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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 package (12 hand traps, 14 negation-text cards)
• Strong Extra Deck closers (K9-X Werewolf 3300 ATK, K9-66X Jacks, Divine Arsenal AA-ZEUS)
• High opening-hand starter access from the 25-copy archetype core

Weaknesses

• Illegal copy-limit violations on two Semi-Limited cards
• No Side Deck, so no post-side adaptation
• Split engine: only 11 exact Crystron copies, with K9 and Mulcharmy taking many slots
• Off-archetype generic tech in the Main Deck lowers compactness

Critical choke points

• Legality fix is mandatory: Ash Blossom and K9-17 Izuna each need to drop from 3 copies to 2
• Unresolved passcode 10443957 must be identified before any consistency read is trusted

Recommended changes

Evidence & confidence

• Verified: Main Deck is 56 cards and Extra Deck is 14 cards, within size rules; Ash Blossom & Joyous Spring and K9-17 Izuna each run 3 copies against a Semi-Limited limit of 2; Side Deck is empty; Exact archetype purity is 15.7 percent
• Inferred: Starter access is about 0.96 from the 25-copy archetype-core hypergeometric estimate; Interaction density is high from negation and removal text; Brick risk is moderate from singletons and hand traps
• Provisional: Meta and matchup fit cannot be assessed without a dated metagame sample
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and pilot match record are absent One passcode (10443957) in the deck could not be resolved to a card and was counted as Main Deck No win-rate telemetry exists in YGOVN for going-first, going-second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied
