R.B. Deck #773412 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Link-monster board pressure: R.B. Link Monsters (Brute Blues, Shepherd's Crook) gaining ATK from the R.B. monsters they point to, with Brute Blues' second attack and indestructibility.; Ecclesia and the Dark Dragon (Synchro, 2500 ATK) and Sky Striker Ace Link lines, the latter gated by a single Roze.
• Turn 1 (going first): Open an R.B. hand-summon starter (Ga10 Cutter, Ga10 Driller, Ga10 Pile Bunker or VALCan Rocket) or Stage Landing, build a second R.B. body, link into Brute Blues or Shepherd's Crook, and keep Ash Blossom or Droll in hand for the opponent's first big summon.
• Turn 2 (going second): Hold the six-card hand for hand traps (Ash Blossom, Droll & Lock Bird, Maxx "C") against the opponent's first summon, use Forbidden Droplet or Ga10 Cutter to answer their board, then rebuild with Funk Dock's search and Stage Landing.
• Recovery: Re-deploy R.B. monsters through Stage Landing (Deck/Extra Deck Special Summon) and Funk Dock's search; Last Stand and Next Phase protect the R.B. board.
• After siding: No side deck is registered (Side Deck size 0), so there is no post-side plan to evaluate.

Why it scores here

The deck opens a functional R.B. plan reliably enough: 13 cards in the list can start or enable the plan (four single-copy hand-summon R.B. monsters plus Stage Landing, Funk Dock and Cyanos), which gives roughly an 88% chance of at least one on the going-first five-card hand (Inferred, hypergeometric approximation). Conversion is credited through the Link R.B. board (Brute Blues, Shepherd's Crook) rather than through any recorded combo, because the evidence contains no parseable boards and the median is unknown, so floor and median are scored well below the ceiling. Interaction is the strongest part of the system: six hand traps, Forbidden Droplet, Crossout Designator and two R.B. traps create layered answers on both turns, which is why it scores on interaction and resilience. Points were deducted for an Extra Deck with dead or conditional slots (Albion the Branded Dragon has no Fallen of Albaz in the list; Galatea needs Orcust or World Legacy material the deck barely runs), a single main-deck Sky Striker Ace (Roze) as the only access point to most Sky Striker links, and the absence of any side deck. Popularity and the archetype's usage core did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.3, Going First ≈ 66, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: unrecoverable choke point (-3); engine conflicts / dead extra slots (-2); banlist exposure (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*61.3 + 0.20*54 - 5 = 54.8, rounded to 55

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Layered interaction across both turns: hand traps, negations and traps
• Multiple independent hand-summon starters and recursion through Stage Landing and Funk Dock
• Brute Blues and Shepherd's Crook provide hard-to-answer Link boards
• All restricted cards are within legal copy limits

Weaknesses

• Albion the Branded Dragon is uncastable with no Fallen of Albaz in the Main Deck
• Sky Striker Link lines depend on a single main-deck Ace (Roze)
• Only 36 of 55 cards are off the exact R.B. name, lowering engine coherence
• No side deck, so no adaptation after game one
• Core usage cards such as Sky Striker Ace - Kagari and Exceptional Schedule are absent (17 of 25 core cards present)

Critical choke points

• Roze, the single main-deck Sky Striker Ace access point
• The four hand-summon R.B. monsters, which need no face-up monsters or only R.B. monsters on the field

Recommended changes

Evidence & confidence

• Verified: Deck is Legal for master-duel: 40 Main, 15 Extra, 0 Side, all restricted cards within legal copy limits; Card text for Albion (requires Fallen of Albaz) and absence of Fallen of Albaz from the list; Hypergeometric draw probabilities from the evidence; Guide snippet exists for R.B. (Vietnamese text, claims are unverified)
• Observed: Archetype usage: 17 of 25 core cards present (68%)
• Inferred: Opener access ≈ 0.88 going first, computed from a 13-card set; Interaction density and semantic negation reads from card text; Going-first and going-second power estimates from dimension blend; Sky Striker link lines depend on Roze as the only Main-Deck Ace
• Provisional: Meta Power (null) and matchup fit (D13 = 50); Tournament reliability and side-deck adaptability, since there is no side deck and no tournament data
• 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 absent no side deck registered, so post-side evaluation is impossible no win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) Meta Power is provisional without a dated metagame sample the only guide is in Vietnamese and has no section structure
