R.B. Deck #767854 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Tempo, Control
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link-based R.B. board pressure: R.B. Link Monsters (Brute Blues, Shepherd's Crook) are not present, so the closing line is only partially supplied by the Extra Deck (Inferred); Sky Striker Ace Link summons and Mulcharmy disruption (Inferred)
• Turn 1 (going first): Open on R.B. Stage Landing or Funk Dock to reach an R.B. Link route, backed by Ash Blossom and Infinite Impermanence to protect the first combo (Inferred)
• Turn 2 (going second): Use the six-card hand's hand traps (Ash Blossom, Droll & Lock Bird) and R.B. Next Phase or Last Stand to disrupt the opponent's first board before summoning (Inferred)
• Recovery: Recover via R.B. Lambda Cannon GY recursion and Operation Test GY special summons; no combo data to confirm the recovery line (Inferred)
• After siding: Not evaluable: side deck is empty (0 cards), so there is no post-side plan

Why it scores here

The deck's structural read is a Midrange R.B. shell with a Link-based Extra Deck and seven hand traps plus about fifteen negation/removal texts, which supports interaction and resilience. Its archetype core is reasonably reachable (archetype-core group open in at least one opening hand about 98.7% of the time), but the specific engine starters are only about 34% likely in a 5-card opening hand (Inferred). Two 100% and 60% inclusion core cards (R.B. The Brute Blues and R.B. Shepherd's Crook) are missing, and there is no combo, tournament, or win-rate evidence, so the floor and median are not measurable. The deck is Illegal (Ash Blossom at 3 copies over the Semi-Limited limit of 2), so the structural score is theoretical only and capped at 30; no side deck means no post-side plan. Popularity and archetype share did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); illegal_cap (-13). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*52 + 0.20*45 ≈ 51, then Illegal cap applied: final shown as 30 (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 highly accessible (≈98.7% at least one R.B. card in hand5)
• Seven hand traps and about 15 negation/removal texts give layered interaction
• Extra Deck of 15 Links gives flexible board-building routes

Weaknesses

• Illegal as built: Ash Blossom at 3 copies exceeds the OCG Semi-Limited limit of 2
• Core Link monsters R.B. The Brute Blues (100% inclusion) and R.B. Shepherd's Crook are missing
• 33 off-archetype copies lower engine coherence
• No side deck, so no post-side plan

Critical choke points

• Single-copy engine starters (Ga10 Driller, Therion Regulus, Operation Test, Lambda Cannon, Ga10 Pile Bunker) each have ~12.5% odds in hand5
• Legality: a third Ash Blossom must be removed before the list can be played

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring at 3 copies, Semi-Limited limit 2; Main 40, Extra 15, Side 0 against OCG size rules; Archetype purity 40% exact-name; 33 off-archetype copies; Missing core cards: R.B. The Brute Blues (100%), R.B. Shepherd's Crook (60%)
• Inferred: Hypergeometric starter access (Stage Landing ≈0.34; archetype core ≈0.987); Midrange primary strategy from Link engine plus interaction density; Going-first and going-second plans from card text
• Provisional: Meta power: no dated metagame sample; Matchup fit and tournament reliability: no tournament context
• 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 win-rate telemetry (going-first/second, matchup, brick/starter rates) Side deck is empty, so post-side adaptability cannot be measured Meta Power is Provisional unless a dated metagame sample is supplied
