Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±7 · Confidence: Medium)

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

Legality

Main 60 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Large LIGHT/DARK Machine boss monsters from the B.E.S. core (Super B.E.S. Metal Slave, B.E.S. Big Core MK-3, B.E.S. Blaster Cannon Core) and Extra Deck closers such as Varudras, Super Starslayer TY-PHON and Tri-Brigade Arms Bucephalus II; Card-advantage grind through Mulcharmy draw effects, Pot of Sloth and recursion of Boss Rush targets
• Turn 1 (going first): Open with a B.E.S. Core or Boss on Parade search, then Boss Rush or B.E.F. Zelos to convert the searched boss into a board of 3-counter B.E.S. monsters
• Turn 2 (going second): Use Maxx C and Triple Tactics Thrust or Talent to punish the opponent's summon, then rebuild through B.E.S. Big Core or Blaster Cannon Core Special Summons from hand
• Recovery: Searchers (Cyber Repair Plant, Cyber Dragon Core, Derringer Core, A-Assault Core) and Boss Rush recursion of B.E.S. monsters from the Deck after a board wipe
• After siding: Not applicable: the Master Duel format has no Side Deck in this list (Side Deck size 0)

Why it scores here

The deck reliably opens its core: 22 archetype-core copies give about a 0.91 chance of at least one in a 5-card opening hand, and 21 searcher-text cards give about 0.89, so the engine is usually live by turn 1 to 2 (Inferred). Its ceiling comes from text rather than recorded boards: boss monsters with counters, Boss Rush recursion and Extra Deck closers can produce a large field, which earns the closing and combo-ceiling scores. The score is held down by a 35-spell main deck that mixes four or more sub-archetypes (B.E.S., Cyber Dragon, Mulcharmy, Tri-Brigade, Ignister and Chimeratech) with only 20 percent exact-name purity, and by an Extra Deck that spans Fusion, Synchro, Xyz and Link access with little shared engine. There is no recorded board data, no tournament link and no Side Deck, so floor, median and post-side adaptation are scored from text and marked provisional. Usage statistics and archetype popularity confirm the list is a real, accessible build, but they earned no points on their own, and the card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 60, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine conflicts (-3); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers (-5); 0.80*56.7 + 0.20*52 = 56.0, then 56 - 5 = 51

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · key two-card combo ≈ — · full-brick estimate ≈ 0.09 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is reliably accessible: about 0.91 chance of at least one core card in a 5-card opening hand
• Multiple searchers and recursion routes (Cyber Repair Plant, Derringer Core, Boss Rush) support continuation after disruption
• Layered interaction: Heavy Storm, Feather Duster, Lightning Storm, Evenly Matched, Gordian Slicer and Maxx C
• High-ATK closers (Metal Slave 3100, Bucephalus II 3500, Varudras 3000, TY-PHON 2900)

Weaknesses

• Only 20 percent exact-name archetype purity; the deck mixes B.E.S. with Cyber Dragon, Mulcharmy, Tri-Brigade, Ignister and Chimeratech
• 35 spells and conditional cards (Triple Tactics, Clockwork Night, Illusion Gate) raise dead-draw risk
• Extra Deck spans four summon types and roughly eight sub-archetypes, so it lacks a shared engine
• No Side Deck in the list, so post-side adaptation is absent

Critical choke points

• The B.E.S. boss monsters need Boss Rush, B.E.F. Zelos or Boss on Parade to be live; losing these removes the main conversion
• Triple Tactics Thrust and Talent need an opponent's monster effect to activate, so they can be dead on a turn-1 plan

Recommended changes

Evidence & confidence

• Verified: Legal in Master Duel: 60 main, 15 extra, 0 side; no banned or over-limit cards; Limited cards (Feather Duster, Heavy Storm, Maxx C) run at 1 copy; Super Polymerization runs 2 copies (Semi-Limited); Copy histogram 1x18, 2x3, 3x12 and archetype purity 20 percent; Card text for the listed boss monsters, searchers and interaction cards
• Observed: Archetype usage: 100 percent of the listed core cards in the usage table are used at the typical copy count (main-deck core only)
• Inferred: Consistency: P(at least one core card in hand5) = 0.91 and searcher P = 0.89; Interaction density from text: 28 removal-text and 6 negation-text cards; Ceiling from boss and closer text, with no recorded boards; Going-first and going-second estimates from card text and structure
• Provisional: Meta power (no dated metagame sample); Matchup fit and tournament reliability (no tournament link); Side deck adaptability (no Side Deck in format)
• 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 are absent No win-rate telemetry exists for this deck (going-first/second, matchup, brick and starter rates) usage statistics marks 12 Extra Deck cards (for example Mudragon, Garura, TY-PHON) as in this deck:false even though the cards array lists them as zone extra; the usage-based core-present percentage (48) is therefore unreliable Deck title is null in the source record Meta Power is Provisional because no dated metagame sample is supplied
