R.B. Deck #770363 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Blind-Second/OTK, Toolbox
• Format: master-duel

Legality

Main 43 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link-based R.B. board: Brute Blues and Shepherd's Crook gain ATK from R.B. monsters and attack through 1500+ ATK bodies, with Brute Blues' second attack and indestructibility for the close.; Interaction-led attrition: hand traps and negates stall the opponent's engine, then R.B. recursion and LP gain keep the board ahead.
• Turn 1 (going first): Hand-summon an R.B. monster (Ga10 Driller, Ga10 Cutter, Ga10 Pile Bunker, VALCan Rocket) or Funk Dock / Stage Landing into a Link 2-3 R.B. Link; hold Forbidden Droplet and Ash Blossom for the opponent's first combo.
• Turn 2 (going second): Hand traps first (Ash Blossom, Droll & Lock Bird, Maxx C) to break the opponent's starter, then Stage Landing or a hand-summon R.B. monster to rebuild the board.
• Recovery: R.B. Operation Test and Stage Landing revive from the GY, Lambda Blade and Lambda Cannon return R.B. cards, and Scrap Recycler draws off Level 4 EARTH Machines.
• After siding: None: the list runs no side deck, so there is no post-side plan to evaluate.

Why it scores here

The deck reliably opens an R.B. engine: 14 R.B. cards are in the Main Deck, so about 88% of opening 5-card hands contain at least one (Inferred, hypergeometric), and the 28 archetype-core copies make a dead hand almost impossible. Its strongest scoring factor is interaction density: six hand traps, three Forbidden Droplet, Next Phase and Cutter give a layered answer to the opponent's first combo (D7 80), and Maxx C and Droll cover both turns. Conversion is credible but untested, since no recorded boards exist and the link and ATK-boost text (Brute Blues, Shepherd's Crook) is the only evidence for the ceiling. The score is not based on the archetype's popularity, which the data cannot confirm, and it does not average card scores; the deductions come from four Extra Deck slots whose materials are not in the Main Deck (Sky Striker Aces, Albion), an off-archetype splash spread across Train, Scrap, Mulcharmy and Forbidden, and the absence of any side plan.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 62, Going First ≈ 66, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-2); engine conflict / dead Extra slots (-2); off-archetype splash (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then context modifiers: 0.80*62.1 + 0.20*58 = 61.3; 61.3 - 6 = 55.3 -> 55

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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

• Archetype core is dense: 28 R.B.-core copies make a dead opening hand almost impossible
• Layered interaction: 6 hand traps, 3 Forbidden Droplet, Next Phase, Cutter and Fallen & Virtuous
• Redundant GY recursion (Operation Test, Stage Landing, Lambda Blade, Lambda Cannon)
• Brute Blues and Crook give a real ATK and second-attack closing route

Weaknesses

• Four Sky Striker Ace links appear to have no Sky Striker Ace material in the Main Deck
• Albion needs Fallen of Albaz, which is not in the list; Ecclesia's Fallen search also has no target
• Off-archetype splash (Train, Scrap, Mulcharmy, Forbidden) dilutes the engine
• No side deck, so no post-side plan
• No combo data, so the ceiling is text-only

Critical choke points

• Maxx C, Droll and Ash are the only answers to a non-R.B. starter; losing the R.B. Link board removes the closing route
• Brute Blues and Crook are each 2 copies in the Extra Deck, so losing both removes most of the closing power

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 43 Main / 15 Extra / 0 Side within size rules; Maxx C and Hornet Drones at 1 copy each (Limited); Droll and Fallen & Virtuous at 2 copies each (Semi-Limited); Copy histogram and Extra Deck breakdown (12 Link, 2 Synchro, 1 Fusion) match the card list
• Observed: Usage statistics show R.B. Funk Dock, Stage Landing and Exceptional Schedule in 100% of listed decks
• Inferred: Opening-hand probabilities (hypergeometric, Main Deck only); Dead-slot reading of the Sky Striker Ace links and Albion from card text; Midrange primary strategy, with Blind-Second/OTK and Toolbox as secondaries
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13)
• 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 in YGOVN for going-first/second, matchup, brick or OTK rates Meta Power is Provisional without a dated metagame sample usage statistics in this deck flags conflict with the card list: Dawn Dragster, Kagari, Amatsu, Camellia and Shepherd's Crook are in the cards list but marked in this deck=false; the card list was treated as the source of truth no side deck, so no Bo3 post-side evidence whether the Hornet Drones Sky Striker Ace Token counts as a Sky Striker Ace monster for the Link material requirement is unverified
