R.B. Deck #774143 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Stun
• Format: tcg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link-chained R.B. boards (R.B. Shepherd's Crook, R.B. The Brute Blues, R.B. VALCan Booster) plus Super Starslayer TY-PHON as a single-card Xyz finisher; the Super Starslayer line is only one copy and is not reliably reachable; Sky Striker Ace link monsters chained off Sky Striker Mecha - Hornet Drones and the Mecha Phantom Beast Tetherwolf / O-Lion token line
• Turn 1 (going first): Open a hand-trap-backed starter (Effect Veiler, Ghost Ogre & Snow Rabbit, Ghost Belle, Ash Blossom) and hold interaction for the opponent's first Main Phase; a full combo turn-1 is not evidenced in the data
• Turn 2 (going second): Use the six-card hand's roughly 95% chance of at least one hand trap to answer the opponent's first summon or search, then rebuild through R.B. Stage Landing or Mulcharmy draw effects
• Recovery: Re-summon from GY through R.B. Operation Test, R.B. Stage Landing and Mecha Phantom Beast O-Lion's GY effect, and re-enter Link monsters from the Extra Deck
• After siding: No side deck is run, so there is no post-side plan; any adaptation is structurally unavailable

Why it scores here

The deck reliably opens a hand-trap-backed starter: with 21 hand-trap-type cards, the going-second six-card hand has an estimated 95% chance of holding at least one (Inferred). Its interaction is layered across several negation and removal effects (Ash Blossom, Ghost Belle, Effect Veiler, Infinite Impermanence, Droll and Lock Bird), which carries the structural score. Conversion is weaker: no recorded boards exist, so the combo ceiling and median are text-only inference, and the 3-copy starters each have only about a 25% chance of appearing in a 5-card opening hand. Popularity and archetype usage were not credited, and the score does not come from averaging card scores; the deck is also Illegal (Ash Blossom at 3 copies against a limit of 2), so the final score is theoretical and capped low.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 52.4, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegal copy limit (-8); No side deck (-4). Final formula: No reliable metagame: Final = 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*52.4 + 0.20*42 - 12 = 38.3, rounded to 38 (Illegal, so theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 interaction: 21 hand traps and layered negation/removal across several archetypes
• Strong going-second hand-trap access (about 95% in 6 cards)
• Redundant starters across the R.B., Mulcharmy and Mecha Phantom Beast lines

Weaknesses

• Illegal list: Ash Blossom at 3 copies exceeds the Semi-Limited limit of 2
• Low archetype purity (32.4%) and many off-archetype hand traps compete for slots
• No side deck, so no adaptability
• No recorded boards, so the combo ceiling and median are unknown

Critical choke points

• Only one copy of Super Starslayer TY-PHON - Sky Crisis, the sole Xyz finisher
• Link chains depend on specific R.B. Link monsters, and several are single copies
• Going first, a single hand-trap-less opening hand has roughly a 75% chance of no interaction

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom 3 copies vs limit 2 (Semi-Limited); Main 56, Extra 15, Side 0 within size rules; Card text and banlist status for all listed cards; archetype purity 32.4% (exact name); usage statistics: 15 of 25 core cards present
• Observed: Mulcharmy and Mecha Phantom Beast lines present in the list as recorded structure
• Inferred: P(at least one 3-copy starter in 5) approx 0.25; P(at least one hand trap in 6) approx 0.95; Interaction density and resilience read from card text; Going-first and going-second estimates
• Provisional: Meta power (no dated metagame sample); Format fit (no tournament context)
• Data gaps: no combos supplied, so combo floor, median, and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot record are absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied No side deck, so post-side evaluation is not applicable
