R.B. Deck #755660 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Stun
• Format: ocg

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Link-based R.B. board (Brute Blues, Shepherd's Crook, Regulus, TY-PHON as end-board threats) built through the R.B. link engine (Inferred from card text); Stun-style board control with negations and Regulus pressure, converting the resulting tempo into attacks (Inferred)
• Turn 1 (going first): Open a 3-copy starter (R.B. Stage Landing or R.B. Funk Dock) and search or summon into the R.B. link chain; keep Ash Blossom or Droll for the first interruption (Inferred)
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Droll) to stop the opponent's first engine, then rebuild through R.B. Operation Test or Lambda Cannon recursion (Inferred)
• Recovery: Recover R.B. monsters from the GY with Lambda Cannon and Operation Test, and Pot of Sloth for card flow (Inferred)
• After siding: Not evaluable: the deck runs no side deck (0 cards), so there is no post-side plan

Why it scores here

The deck is scored as a system: its R.B. starters (3-copy Stage Landing and Funk Dock) give about a 26% chance of at least one in a 5-card opening hand, and the R.B. link chain converts those starts into multi-link boards. Its interaction suite (Ash Blossom, Ghost Belle, Droll, Solemn, Crossout Designator, Harpie's Feather Duster, Regulus) makes it hard to disrupt on the first turn, and the 6-card going-second hand has about a 64% chance of holding a hand trap. Popularity of the archetype (R.B. core inclusion) and the card-level strength of individual cards were not averaged into the score. The deck is Illegal in OCG (three Semi-Limited/Limited copy overages, one Forbidden card, and a 16-card Extra Deck), so the score is capped and reported as theoretical/structural only. There are no recorded boards, no side deck, and no meta sample, so the ceiling and floor cannot be measured.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); extra deck over size (-2). Final formula: Illegal deck: theoretical/structural-only. Uncapped 0.80*54 + 0.20*45 + modifiers (-8) = 44; capped to 30 because the list is illegal. Meta Power is null (provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.26 · 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

• Three-copy R.B. starters give a repeatable opening
• Heavy negation and hand-trap suite gives first-turn and going-second interaction (Inferred)
• Strong link-based end-board threats in the Extra Deck

Weaknesses

• Illegal in OCG on three copy-limit overages, one Forbidden card and Extra Deck size
• Exact archetype purity is low (32.9%), so the engine is split across Sky Striker, Mekk-Knight, Mulcharmy and Therion
• No side deck, so no best-of-3 adaptation
• Large tech and hand-trap count raises dead-card risk on non-engine hands

Critical choke points

• Single 3-copy starter family (Stage Landing, Funk Dock) carries the opening
• The Extra Deck link routes depend on specific R.B. link monsters being in the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal, with four copy or ban violations and Extra Deck size 16 over 15; Main Deck size 54 is within the 40-60 range; Card text for the listed starters, negation and hand-trap cards; Usage statistics show the R.B. core is common in this archetype (inclusion 68-95%)
• Inferred: Engine accessibility and consistency from hypergeometric probabilities (~0.26 for a 3-copy starter); Going-second hand-trap availability (~0.64); Combo and engine behaviour from text only, because no boards are recorded; Strategy classification as Midrange with Toolbox and Stun secondaries
• Provisional: Matchup and format fit (D13), no dated meta sample; Meta Power (null)
• Data gaps: Usage statistics in_this_deck is false for Extra Deck cards (R.B. The Brute Blues, R.B. VALCan Booster, Barricadeborg Blocker, Sky Striker Ace Hayate, Kagari, Amatsu, Clockwork Knight, R.B. Shepherd's Crook) even though the cards list includes them in the Extra zone. missing_core therefore overstates the missing core; it is a data artifact, not a real absence No combos supplied; combo floor, median and ceiling are text-only inference No side deck (0 cards), so post-side adaptability cannot be measured No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is provisional unless a dated metagame sample is supplied deck title is null
