Crystron Deck #754578 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±6 · Confidence: Medium)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro Summon 3000-ATK boss monsters from the Extra Deck (Quariongandrax, Gymir Aegirine, Baronne de Fleur, Chengying, Snake-Eyes Vengeance Dragon) after a Crystron tuner chain; Cyber Dragon Infinity and Cyber Eternity Dragon as alternate Extra Deck finishers, both dependent on Cyber Dragon cards that are only partly present
• Turn 1 (going first): Open a Crystron or Tuner starter, search or summon a second Crystron piece, and Synchro into a 3000-ATK boss; hold Ash Blossom, Infinite Impermanence, or Effect Veiler for the opponent's first activation
• Turn 2 (going second): Use the hand traps (Ash Blossom, Impermanence, Effect Veiler, Droll and Lock Bird, Maxx C, Dominus Impulse) to stop the opponent's board, then Synchro over the resulting field
• Recovery: Rebuild from the GY: Crystron Smiger, Thystvern, Tristaros and Eleskeletus recover Crystron pieces, and Crystron Inclusion adds another from the Deck
• After siding: No Side Deck is registered (0 cards), so there is no post-side plan in the evidence; any sideboard-based adjustment is unevaluated

Why it scores here

The deck reliably opens a Crystron engine: nine core-archetype copies give about a 73% chance of at least one in a 5-card opening hand (Inferred), and the 3-copy starters plus Crystron Inclusion and the GY recursion pieces give several independent restart routes. Its strongest scores come from the system, not the cards: eleven hand traps and thirteen negation-text cards make it hard to stop once it has a board, and the Extra Deck carries several 3000-ATK Synchro bosses. Brick risk is real, since thirteen tuners in the main deck create tuner-only hands, and the deck's combo floor and median are only text-inferred because no boards were recorded. Popularity did not earn points: the archetype usage data shows this list runs only 5 of 25 archetype-core cards, and no tournament or win-rate data exists. Card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange, meta-neutral (D13 dropped and re-normalized over 95). Structural ≈ 60, Going First ≈ 58, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: engine conflicts (-3); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Structural = Midrange weights with D13 dropped and re-normalized over 95: 5742/95 = 60.4)

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

• Strong interaction density: 11 hand traps and 13 negation-text cards cover the opponent's first turn in both going-first and going-second scenarios
• Several 3000-ATK Synchro bosses in the Extra Deck give real closing power
• Recursion from the GY (Smiger, Thystvern, Tristaros, Eleskeletus) plus Crystron Inclusion gives the deck a way to rebuild

Weaknesses

• High tuner density (13 in the Main Deck) raises the chance of tuner-only hands
• Only 18 of 41 Main Deck cards are exact Crystron names; the rest are generic or from other sub-archetypes, which lowers engine coherence
• No Side Deck registered, so there is no adaptability to a bad matchup
• Only 5 of 25 archetype-core cards are present (usage data), so the list departs from the standard archetype build

Critical choke points

• A single Crystron starter that the opponent negates before it resolves can stall the Synchro line; the guide notes that one card into a choke point can lie the whole board flat
• Dependence on one Extra Deck boss per line: the 3000-ATK Synchros are the main closing route

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 41 Main, 15 Extra, 0 Side, all restricted cards within legal copies; Archetype purity 18/41 exact Crystron names (32.1%); Archetype usage data: 5 of 25 core cards present (20%); Hypergeometric numbers from the probabilities block
• Inferred: Engine accessibility of about 0.73 for at least one core card in the opening hand; Brick risk from 13 tuners; Going-second interaction coverage of about 0.87; Recursion and restart routes from the card text
• Provisional: Meta fit and matchup (D13) is provisional with no dated metagame sample or tournament link; Side Deck adaptability (D12) is provisional with no registered Side Deck
• 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 No win-rate telemetry for going-first, going-second, matchups, or starter/brick rates Meta Power is provisional without a dated metagame sample No Side Deck registered, so post-side evaluation is unavailable
