Chaos Deck #49291 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 33/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual and Fusion boards built from Dark Magician-named monsters, ending in Dark Magician the Dragon Knight, Master of Chaos or a 3000-ATK Link/Xyz finisher; Dark Magician Girl and Apprentice Illusion Magician beats, supported by Chaos Ritual and Link extenders
• Turn 1 (going first): Search a Dark Magician or Ritual monster with Magician's Rod, Soul Servant or Magicians' Souls, then Ritual Summon Illusion of Chaos through Preparation of Rites and open a Fusion line with The Eye of Timaeus or Secrets of Dark Magic
• Turn 2 (going second): Hold Ash Blossom & Joyous Spring to break the opponent's first starter, then rebuild from the graveyard with Magician's Souls and Soul Servant
• Recovery: Recover searchers and Dark Magician-named monsters from the graveyard through Magician's Rod, Magicians' Souls and Dark Magic Circle
• After siding: No side deck is registered, so no post-side plan can be scored; the list has nothing to swap into for a second game

Why it scores here

This list is illegal in Master Duel because it runs two Called by the Grave and one Terraforming, all Forbidden, so the score is a structural, theoretical read only and is capped low. The engine is a Dark Magician core: the nine copies of the archetype core give about a 74% chance of at least one in a 5-card opening hand, and sixteen searcher-text cards make a first starter likely. Conversion is the weak point, because no recorded boards exist and the Ritual and Fusion lines are inferred from card text alone. The deck has three hand traps and eight negation-text cards for interruption, but 22 of its 40 main deck cards are Spells with no Level, 51 copies are off-archetype, and the Extra Deck spreads across Link, Fusion and Xyz sub-archetypes, which weakens coherence. Popularity and archetype identity did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 46, Going First ≈ 45, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); no_side_plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal cap applied, so this is a theoretical structural-only score

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Dark Magician core is dense enough for a reliable first starter (about 74% in a 5-card hand)
• Sixteen searcher-text cards and graveyard recursion give resource recovery
• Three hand traps plus eight negation-text cards cover interruption

Weaknesses

• Two Forbidden cards and one more Forbidden card make the list illegal in Master Duel
• Zero side deck cards means no post-side adaptation
• Half the main deck is Spells with no Level, and most copies are off-archetype, which weakens the engine
• Extra Deck spreads across five sub-archetypes with no shared engine

Critical choke points

• The Dark Magician core: a hand without any of the nine copies has no engine (about 26% of opening hands)
• Illustration of Chaos Ritual requires a Ritual Monster in hand, which is not guaranteed by the searchers

Recommended changes

Evidence & confidence

• Verified: Two Forbidden cards (Called by the Grave x2, Terraforming x1) are run; Main deck is 40 cards and Extra Deck is 15, both within Master Duel size rules; Zero side deck cards are registered; Archetype is Chaos with 7.3% exact-name purity
• Observed: Copy histogram: 7 single copies, 3 double copies and 9 triple copies; Extra Deck is 7 Link, 5 Fusion and 3 Xyz; 22 of 40 main deck cards are Spells with no Level
• Inferred: About 74% chance of at least one archetype-core card in a 5-card opening hand; Ritual and Fusion conversion ceiling is estimated from card text alone; Interruption resilience and resource recovery from negation and searcher text
• Provisional: Format fit and matchup coverage, because no dated metagame sample exists
• Data gaps: No recorded combos are attached, so floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry exists for going-first, going-second, matchups or brick rates Meta Power is provisional until a dated metagame sample is supplied Deck title is null, and the side deck is empty
