R.B. Deck #771420 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: R.B. link-board pressure: R.B. Link monsters (Brute Blues, Shepherd's Crook) with R.B. Stage Landing and Funk Dock recursion, closing through Link attacks and Ga10 monsters; Train Level 10 Machine boards (Night Train Blue Traveler, Heavy Armored Knight Babeldecker) for Diagram Token pressure
• Turn 1 (going first): Open on R.B. Stage Landing or Night Train searcher, Special Summon an R.B. monster, build a Link-2/3 board, and hold Ash Blossom or Solemn for the first interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Droll & Lock Bird) to slow the opponent's first summon, then convert with R.B. Next Phase or Lambda Cannon once a Link board is up
• Recovery: Rebuild from R.B. Funk Dock and the GY recursion effects (Lambda Blade, Ga10 Driller, VALCan Rocket), plus Pot of Sloth or Pot of Prosperity to refill the hand
• After siding: Not evaluable: Side Deck size is 0, so there is no post-side plan

Why it scores here

The score is capped at 30 because the list is Illegal: three copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of two, so this is a theoretical, structural-only read. Within that limit the system is coherent: the R.B. core has about a 91% chance of at least one core card in a going-first five-card hand (Inferred), and the three-copy staples give repeated access to the engine. Its interaction suite (Ash, Ghost Ogre, Droll, Typhoon, Next Phase, Solemn) supports the Midrange profile. Ceiling and median output are unmeasured because there are no recorded boards, so D3 and D4 rest on card text alone. The score does not come from R.B. being a popular archetype, and it does not come from averaging the card scores. Off-archetype density (about 66% of main copies are not exact R.B. names) and the absence of any side deck pull it down.

Dimension scores

How the score was computed

Strategy profile: Midrange 100%; secondary strategies not blended. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); no Side Deck (-4); engine conflicts (-2). Final formula: Theoretical only (Illegal). Uncapped: 0.80*53 + 0.20*45 + modifiers(-12) ≈ 40; capped at 30 because the list fails copy-limit legality. Meta Provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · key two-card combo ≈ — · full-brick estimate ≈ 0.09 (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. staples and Train searchers give repeatable starts
• Dense hand-trap and negation suite supports both going-first and going-second interaction
• Extra Deck is compact (15 Links, 6 distinct) and covers the core Link set

Weaknesses

• Illegal list: Ash Blossom is run at 3 copies against a limit of 2
• No side deck, so no best-of-3 adaptation
• Off-archetype spread dilutes the engine and adds brick risk

Critical choke points

• Single-card legality fix needed before any normal score can apply (cut 1 Ash Blossom)
• R.B. Link Monster presence in the Extra Deck is the single pressure route
• No recorded boards, so the ceiling cannot be confirmed

Recommended changes

Evidence & confidence

• Verified: Main 55 / Extra 15 / Side 0 within OCG size rules; Ash Blossom & Joyous Spring 3 copies vs legal 2 (violation); Limited cards (Droll, Feather Duster, Pot of Prosperity) run at 1 copy, which is legal; Extra Deck composition: 15 Link monsters across 6 distinct names
• Inferred: P(at least one core card in going-first hand of 5) ≈ 0.91; Going-second hand-trap density (P ≥1 hand trap in six ≈ 0.52); Structural profile and dimension scores are text-based reads, not match data
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13); Ceiling and median output (no recorded boards)
• 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 are absent No win-rate telemetry exists in YGOVN for this deck usage statistics in this deck flags ignore Extra Deck copies: R.B. The Brute Blues (3), R.B. Shepherd's Crook (3), R.B. VALCan Booster (3), and Clockwork Knight (2) are marked absent but are in the Extra Deck. Core present is likely about 16/25 (64%), not 12/25 (48%). Inferred from the export. Meta Power is Provisional unless a dated metagame sample is supplied
