R.B. Deck #765004 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: R.B. Link and Machine monsters swarm the field and pressure with high-ATK bodies (R.B. The Brute Blues, R.B. Shepherd's Crook, Sky Striker Aces) once a field of R.B. monsters is established; Sky Striker and Train Link pressure with Lambda Blade and Cutter recursion-based boards
• Turn 1 (going first): Open with R.B. Stage Landing, Exceptional Schedule or Funk Dock to find an R.B. Link route and keep Ash Blossom, Maxx C or Droll up as interaction into the first Link Summon
• Turn 2 (going second): Use the six-card hand to hold Ash Blossom, Forbidden Droplet, Forbidden Crown or R.B. Next Phase against the opponent's first board, then rebuild through Mulcharmy draws and Scrap Recycler
• Recovery: Recover through Mulcharmy Fuwalos and Purulia draws, Scrap Recycler draws, and Night Train Blue Traveler recursion from the Graveyard
• After siding: No side deck is registered (side count 0), so there is no post-side plan in the export

Why it scores here

The score is built from the deck as a system, not from its cards. The R.B. core (31 copies, about 98 percent to appear in an opening five by the hypergeometric proxy) gives the engine reasonable access on turns one and two, and the deck has broad interaction across Ash Blossom, Maxx C, Droll and Lock Bird, Forbidden Droplet, Forbidden Crown, R.B. Next Phase and R.B. Last Stand, which keeps interruption resilience and end-board quality above average. The deck has no recorded boards, so its ceiling and median are text-based and Inferred only, and no materialized win rate or metagame sample exists to lift the score. Popularity and archetype usage did not earn points, and the deck's low archetype purity (29 percent exact-name) and missing side deck cap its structural and post-side scores. Card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, no separate weighted blend applied to secondary. Structural ≈ 58, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-1); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*57.7 + 0.20*55 - 3 = 54.2

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Core R.B. enablers reach the opening hand reliably (about 98 percent for the core group)
• Broad quick-effect interaction across hand traps, Droplet, Crown and Next Phase
• Draw and recursion engines (Mulcharmy, Scrap Recycler, Night Train) help recover from disruption

Weaknesses

• No side deck, so no post-side adaptation
• Low archetype purity with splash lines from Sky Striker, Train, Crystron and Mulcharmy
• Many single-copy slots raise brick and misfire risk

Critical choke points

• Single copies of Maxx C, Foolish Burial and Crossout Designator are Limited; losing one to a removal or disruption leaves a gap
• Turn-one Link routes depend on R.B. Stage Landing and Exceptional Schedule being drawn

Recommended changes

Evidence & confidence

• Verified: Main 60, Extra 15, side 0 are inside Master Duel size rules; All restricted cards are legal at the copies run; Archetype purity 29.3 percent and 21 singleton main-deck slots; Hypergeometric opening-hand probabilities for core groups
• Inferred: Midrange primary strategy from composition and card text; Dimension scores from card text and hypergeometric estimates; Interaction density and resilience read from quick-effect card text
• Provisional: Meta Power is null and tournament reliability is provisional without a dated sample; Matchup coverage (D13) is provisional
• 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 and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics in_this_deck flags conflict with the card list for Sky Striker Ace - Hayate, Prototype Sky Striker Ace - Amatsu, Sky Striker Ace - Camellia, Sky Striker Ace - Kagari, F.A. Dawn Dragster and R.B. Shepherd's Crook; the card list (which sums to 15 Extra) was trusted side deck is empty, so D12 and any post-side plan are unmeasured
