R.B. Deck #762128 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±6 · Confidence: Medium)

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

Legality

Main 45 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link-based R.B. board of Link monsters with R.B. Lambda Blade, R.B. Ga10 Cutter, Ga10 Pile Bunker and VALCan Rocket feeding into 1500+ ATK Link attackers (R.B. The Brute Blues / Shepherd's Crook) for pressure; Sky Striker Ace Links (Hayate, Zeke, Shizuku, Camellia, Kagari) and Synchro/Link burst from the Train and Machina splashes
• Turn 1 (going first): Opening R.B. Stage Landing / Funk Dock plus Ash Blossom / Droll & Lock Bird interaction to set up a first Link Summon into R.B. board, with hand traps held for opposing starters
• Turn 2 (going second): Hand-trap and Maxx "C" based disruption on the opponent's first Link or Synchro, then R.B. Last Stand / Next Phase to protect and rebuild the R.B. board
• Recovery: R.B. monsters in GY recycled through Lambda Cannon, Exceptional Schedule and Night Train; Forbidden Droplet and Crossout Designator to clear interference
• After siding: No side deck; post-side plan is not available in this build (side_count = 0)

Why it scores here

The deck's core engine (31 R.B. copies, 99.8% chance of at least one in an opening hand of five per the hypergeometric estimate) makes it reliably open to a live R.B. body on turn one or two, and the R.B. Link chain gives it a credible floor of board presence. Conversion is strong at the ceiling (R.B. Lambda Blade, Ga10 Cutter and Pile Bunker can create 1500+ ATK Link attackers and protect the board with Next Phase and Last Stand), but no recorded boards exist, so median output is inferred from text and rated lower. Interaction is layered through Ash Blossom, Droll & Lock Bird, Maxx "C", Forbidden Droplet and Crossout Designator, though the R.B.-specific negates are conditional on linked R.B. monsters. The score comes from consistency, median output and interaction on the system as a whole; the R.B. archetype's popularity (its usage stats in the evidence) confirms the list is real but did not add points, and the card scores were not averaged. Side deck is absent, so post-side adaptability is scored at its floor.

Dimension scores

How the score was computed

Strategy profile: primary Midrange with Toolbox secondary, per the deck's role-tag spread (9 searchers, 11 tech, 6 hand traps). Structural ≈ 63, Going First ≈ 62, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: banlist exposure (-2); dependence on Link route (-1); no side deck (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

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

Strengths

• 31 R.B. core copies give near-certain access to an R.B. body in the opening five
• Layered interaction (Ash Blossom, Droll & Lock Bird, Maxx "C", Forbidden Droplet, Crossout Designator, Next Phase, Last Stand)
• Multiple Link routes to 1500+ ATK attackers and recursion via Lambda Cannon / Exceptional Schedule

Weaknesses

• Purity is low at 33.3% exact name: 40 off-archetype copies (Train, Sky Striker, Mulcharmy, Forbidden, Greed) dilute the R.B. engine
• No side deck, so no post-side plan for best-of-3
• No recorded combos or win-rate data; median output and matchup standing are unverified

Critical choke points

• The R.B. Link monsters (VALCan Booster, Brute Blues, Shepherd's Crook) must land for the board to function; losing them to a single disruption strands the Link line
• Crossout Designator and Maxx "C" are single copies; interaction redundancy depends on the R.B.-linked negates

Recommended changes

Evidence & confidence

• Verified: Legal in master-duel: 45 main, 15 extra, 0 side; Limited and Semi-Limited copy limits respected; R.B. core group: 31 copies in deck (archetype_core_group); Exact name purity 33.3% (20 of 60 copies R.B.)
• Observed: Usage stats: 19 of 25 core cards present (76%); Guide snippet confirms the deck's Lock Machine with 1500 ATK or lower intent and going-first interaction role
• Inferred: Consistency and brick rates from hypergeometric estimates; Link route and negation sequencing from card text; Going-first/going-second power split from interaction and starter access
• Provisional: Meta Power and matchup fit (no dated metagame sample)
• 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, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck present — post-side analysis impossible deck title is null
