Crystron Deck #692013 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 67/100 (±5 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Control
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Midrange board control with Machine Synchro/XYZ bosses and layered interaction; Resource attrition via Mulcharmy Fuwalos draws and Chaotic Elements recursion
• Turn 1 (going first): Open Crystron/K9 starter -> search/extend -> Synchro/XYZ boss -> set backrow/hand traps
• Turn 2 (going second): Use Chaotic Elements, Cluster, or Sulfador to break established boards, then rebuild with GY resources
• Recovery: Shuffle/recycle via Crystron Cluster, Sulfador GY effect, and Chaotic Elements to maintain grind
• After siding: Adapt solely through main deck adjustments due to zero side cards

Why it scores here

This deck functions as a resilient Midrange system built around Crystron and K9 engines, leveraging high core consistency (97.6% opener rate) and robust resource generation via Mulcharmy Fuwalos and Chaotic Elements. It reliably converts openings into interactive midrange boards with strong Extra Deck coverage, though its ceiling remains grounded in value rather than explosive OTK potential. The zero side deck significantly hampers post-side adaptability, capping its long-format reliability. Popularity and archetype share did not inflate this score; it reflects the mechanical cohesion and grind capability of the list itself. Card scores were never averaged—this evaluation measures the system’s floor, median, and ceiling holistically.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 73, Going First ≈ 75, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 68. Modifiers: No Side Deck (-5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High core consistency (97.6% opener rate) ensures frequent engine activation
• Strong resource generation via Mulcharmy Fuwalos and Chaotic Elements sustains grind phases
• Robust Extra Deck coverage across Synchro/XYZ/Link enables flexible board construction
• Effective hand trap suite (Ash, Droplet, Maxx C, Droll) provides early disruption

Weaknesses

• Zero side deck limits post-side adaptability in Best-of-3 formats
• Missing several standard core cards (Clockwork Knight, Cyber Dragon Infinity, Foolish Burial)
• Lacks parsed combo data; relies entirely on text inference for floor/median/ceiling
• Moderate offensive pressure compared to dedicated OTK or aggressive strategies

Critical choke points

• Opening multiple non-starter cards despite high core rate can delay engine activation
• Heavy reliance on Graveyard resources makes the deck vulnerable to mass banish or floodgate effects
• Absence of side deck forces adaptation through main deck alone, reducing matchup optimization

Recommended changes

Evidence & confidence

• Verified: Legality confirmed: 40 Main / 15 Extra / 0 Side, Master Duel format.; Core archetype group contains 20 copies with 97.6% opening probability.; Hand trap suite comprises 6 copies including Ash Blossom, Droplet, Maxx C, Droll.; Extra Deck contains 15 distinct cards across Synchro, XYZ, and Link categories.
• Inferred: Engine accessibility and consistency rated high due to dense searcher and starter distribution.; Combo floor and median output estimated at reliable midrange boards with boss monsters and backrow.; Interruption resilience supported by independent Crystron/K9/Mulcharmy lines and GY recovery tools.; Side deck adaptability penalized heavily due to zero side cards.; Matchup fit provisionally assessed as solid against midrange/combo based on hand traps and negates.
• Provisional: Meta Power remains null pending dated metagame sample.; Tournament Reliability estimated at 68 based on structural consistency and grind capacity.
• 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 (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
