Crystron Deck #774330 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: master-duel

Legality

Main 42 / Extra 14 / Side 0 — status: Legal with warning.

Identity & game plan

• Win condition: Synchro, Xyz and Link boards from the K9 and Crystron engines, closing with Werewolf, Jacks, ZEUS or Eleskeletus-style boss monsters; Recursion from GY and banishment (Crystron Tristaros, Crystron Smiger, Ghost Ogre) to rebuild the board after interaction
• Turn 1 (going first): Open on K9 or Crystron starter plus searcher (A Case for K9, Crystron Inclusion) to reach a Level 5 monster and a Xyz or Synchro boss by T2, keeping Ash Blossom, Droll and Maxx C up for opposing draw or search effects
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Maxx C) to break the opponent's board, then rebuild through Crystron or K9 searchers and recursion
• Recovery: Rebuild from GY through Crystron Sulfefnir, K9-17 Izuna, Scrap Recycler and the Xyz/Link recursion lines; Crystron Cluster protects Crystron cards from banishment
• After siding: No side deck is run (side_count 0); post-side adjustment is not available in this build

Why it scores here

The deck reliably opens a functional starter: the archetype-core group has about a 92% chance of at least one core card in a 5-card opening hand, and 11 searcher-text cards support follow-up. Its interaction layer is the main strength, with 8 hand traps, 17 removal-text cards and 4 negation-text cards giving it answers on both turns. Its closing power comes from Extra Deck bosses such as K9-X Werewolf (3300 ATK), Divine Arsenal AA-ZEUS and K9-66X Jacks, and the GY recursion lines let it rebuild after disruption. Score is pulled down by the split between K9 and Crystron (only about 21% of cards share the exact archetype name), the absence of a side deck, and the lack of combo or tournament data. The score reflects consistency, interaction and recovery on the system; it does not reflect the popularity of the Crystron archetype or an average of the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.8, Going First ≈ 64, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-2); engine conflicts (-3); no side deck (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-6)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Archetype-core starter access of about 92% in a 5-card opening hand
• Eight hand traps and 17 removal-text cards give layered interaction on both turns
• Multiple Extra Deck bosses (Werewolf 3300, ZEUS 3000, Jacks 2600) and GY recursion for recovery
• Legal list with copy limits respected, including Limited and Semi-Limited cards

Weaknesses

• K9 and Crystron engines split the deck, leaving 21% exact-name purity
• No side deck, so no post-side adjustment
• Off-core Extra Deck slots (Platinum Gadget, Clockwork Knight, Cyber Dragon Nova, Artifact Durendal) dilute the engine
• No combo or tournament data, so floor and matchup scores are provisional

Critical choke points

• Single Crystron or K9 starter in hand is required to convert the opening into a board; opponent hand traps or Droll on the first search can break the line
• Hand traps are dead when the opponent does not act, which can strand cards in hand on going first

Recommended changes

Evidence & confidence

• Verified: Legal with warning status, 42 main, 14 extra, 0 side within master-duel size rules; Banlist status for Crossout Designator (Limited, 1), Maxx C (Limited, 1), Droll & Lock Bird (Semi-Limited, 2), K9-66a Jokul (Semi-Limited, 2); Archetype spread K9 17, generic 13, Crystron 12, Mulcharmy 5
• Inferred: Opening-hand starter access about 0.92 from hypergeometric draw estimate; Hand-trap and removal coverage from card text; Going-second hand-trap availability of about 0.74; Engine conflict between K9 and Crystron lines
• Provisional: Meta power (no dated metagame sample); Matchup fit and tournament reliability (no tournament link); Floor and median output (no combos recorded)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent 1 passcode (10443957) in CardIDList could not be resolved to a card and was counted as main no win-rate telemetry exists in YGOVN: going-first/second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck present, so D12 cannot be measured from data
