R.B. Deck #767243 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 57 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: R.B. Link-monster board: Link Summon R.B. Link Monsters, then R.B. The Brute Blues and R.B. Shepherd's Crook gain ATK and extra attacks off R.B. monsters they point to (card text, Inferred); Machine Link pressure via Helping Robo for Underwater Combat and Clockwork Knight removal and Link Summons (card text, Inferred)
• Turn 1 (going first): Open with R.B. Stage Landing or an R.B. searcher to reach the archetype core (P(>=1 core card in opening 5) = 0.92), then Link Summon into a Brute Blues or Shepherd's Crook board (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Droll & Lock Bird and Solemn Accusation as hand traps against the opponent's first activation, then rebuild the R.B. Link board (Inferred)
• Recovery: Recover via R.B. Ga10 Driller and R.B. Ga10 Pile Bunker recursion, R.B. Lambda Cannon GY add, and Stage Landing banish-for-protection text (card text, Inferred)
• After siding: None: the deck has no Side Deck, so there is no post-side plan (verified: side_count 0)

Why it scores here

This deck is Illegal as built: three copies of Ash Blossom & Joyous Spring exceed the OCG Semi-Limited limit of two, so it receives a capped, structural-only score of 30 and not a normal Final Contextual score. Structurally it is a R.B. Link-monster Midrange deck that reliably reaches its core, with 22 archetype-core copies giving P(>=1 in opening 5) of about 0.92 (Inferred). Its interaction is the strongest part: 7 hand traps, 28 removal-text cards and 12 negation-text cards give it real end-board and going-second interaction (Inferred semantic read of card text). Its weaknesses are purity and bricks: only 24 of 57 main cards are exact R.B. names, with off-archetype Train, Mulcharmy and Greed cards that do not connect to the Link engine, and the deck has no Side Deck. No combo boards, guides or tournament data exist, so the score comes from consistency, interaction and structure on the system, not from averaging card scores and not from R.B. being a popular archetype.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary, disclosed as 1:0 weighting for structural score; D13 dropped and weights renormalized over the remaining 95 points. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-4); no side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*54.8 + 0.20*48 - 8 = 45.4; Illegal cap applied (theoretical/structural-only) -> 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core reaches the hand reliably (P = 0.92 for at least one core card in opening 5)
• Dense interaction: 7 hand traps, 28 removal-text cards and 12 negation-text cards
• Extra Deck covers several Link routes (Booster, Brute Blues, Shepherd's Crook, Helping Robo, Clockwork Knight)

Weaknesses

• Illegal: Ash Blossom & Joyous Spring at 3 copies against a limit of 2
• Low purity: 48 of 57 main cards are off the exact R.B. name
• No Side Deck, so no best-of-3 adaptation

Critical choke points

• Legality: the list cannot be played in OCG until one Ash Blossom copy is removed
• Brute Blues and Shepherd's Crook as the only large boards; losing them removes most offensive power (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom & Joyous Spring 3 copies over OCG Semi-Limited limit of 2; Main 57, Extra 15, Side 0; sizes within rules; Archetype purity: 24 of 57 exact R.B. copies; Usage: archetype core present 13 of 25 core cards
• Inferred: Opening-hand starter reliability 0.92; Going-second hand trap value; Interaction density from card text; Structural score 54.8 with D13 dropped
• Provisional: Meta power and matchup fit (no dated metagame sample)
• 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 exists in YGOVN for going-first/second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied deck has no Side Deck, so post-side scoring is structural only
