R.B. Deck #774326 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: R.B. Link Monsters (VALCan Booster, The Brute Blues, Shepherd's Crook) building Machine-zone pressure; Brute Blues double attack and ATK gain are the closing route (Inferred from card text); Machine lock and Extra-Deck denial (guide describes locking Machines from the Extra Deck at 1500 ATK or lower; Observed in guide text only)
• Turn 1 (going first): Open R.B. Stage Landing or R.B. Funk Dock plus a Machine starter, extend through R.B. Link Monsters, and hold Ash Blossom, Ghost Ogre or Maxx C for the opponent's first response (Inferred)
• Turn 2 (going second): Use the six-card hand's hand traps (about 76% to hold at least one) to break the opponent's first board, then go to the R.B. link line (Inferred)
• Recovery: Mulcharmy draw effects, R.B. Last Stand or R.B. Next Phase recursion, and Lambda Blade or Lambda Cannon returning R.B. monsters from the GY (Inferred from card text)
• After siding: Not applicable: Master Duel has no Side Deck and the deck runs 0 side cards

Why it scores here

The deck's power comes from the system as a whole, not from an average of its card scores. Its R.B. core (6 Main Deck monsters, 8 R.B. spells and traps, 3-copy Stage Landing and Funk Dock starters) gives roughly a 53% chance of at least one of the two Main Deck starters in a 5-card opening hand (Inferred hypergeometric), and the Extra Deck's R.B. Link Monsters give it a closing route through The Brute Blues' double attack. Its interaction is dense: 9 hand traps and about 12 negation-text cards give roughly a 76% chance of at least one hand trap in a 6-card going-second hand, which is what carries its score on the disruption axis. Its weaknesses are structural: the Extra Deck runs five Sky Striker Ace Link Monsters with no Sky Striker Ace monsters in the Main Deck, so only Camellia can self-start that thread, and only 35% of Main Deck cards match the exact R.B. name, so the deck is a mixed toolbox. Popularity and archetype usage did not earn points, and Meta Power remains provisional because no dated metagame sample is supplied.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57.1, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 53. Modifiers: Engine conflict: Sky Striker Ace Link suite without Main Deck Sky Striker Ace monsters (-4); Off-archetype dilution (-2); Interaction redundancy (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.53 · 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

• Dense hand-trap and negation package gives a high going-second disruption rate
• Multiple independent R.B. starters and draw engines support recovery after interruption
• Extra Deck link route gives a real closing threat via Brute Blues and Shepherd's Crook

Weaknesses

• Sky Striker Ace Link suite has no Main Deck Sky Striker Ace monsters to link from
• Exact-name purity is 35%, so the engine is diluted by off-archetype toolbox cards
• No recorded combos, so floor and ceiling are unmeasured
• Master Duel has no Side Deck, so there is no post-side adaptation

Critical choke points

• Camellia is the only Sky Striker Ace Link that self-starts from two Effect Monsters
• R.B. Stage Landing and Funk Dock (6 copies combined) carry the R.B. starter role

Evidence & confidence

• Verified: Legal under BanMasterDuel: 45 Main, 15 Extra, 0 Side within 40-60 Main and 0-15 Extra; Restricted cards: Maxx C (Limited, 1 of 1), Sky Striker Mecha - Hornet Drones (Limited, 1 of 1), Droll & Lock Bird (Semi-Limited, 2 of 2); Extra Deck: 14 Link, 1 Synchro; 5 Sky Striker Ace Links present; Exact-name purity 35% (21 of 45 Main Deck copies R.B.)
• Observed: Guide snippet (Vietnamese, guide 1367) describes the deck as able to lock Machines from the Extra Deck at 1500 ATK or lower and mix with Sky Striker, Speedroid, and Orcust
• Inferred: Starter access of about 53% for the six R.B. starter copies in opening 5 (hypergeometric); Hand-trap presence of about 76% in going-second 6-card hands; Midrange structural score 57.1 from D1-D14 with Midrange weights; Brute Blues double attack and Shepherd's Crook ATK gain as closing route (card text read)
• Provisional: Meta Power (null) and D13 matchup/format fit: no dated metagame sample or tournament link
• Data gaps: no combos supplied: combo floor, median, and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent usage statistics in this deck flags disagree with the cards list for Extra Deck cards (Sky Striker Ace - Camellia, Kagari, Amatsu, Hayate, Brute Blues, Shepherd's Crook, F.A. Dawn Dragster marked missing or 0 copies while listed in cards with copies 1-2); core-card presence 72 is unreliable and was not used no win-rate telemetry: going-first and going-second splits, matchup, and brick rates are Inferred only Meta Power provisional unless a dated metagame sample is supplied
