Bystial/Byssted Deck #773006 — 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 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Blackwing and Bystial synchro/link boards (Silverwind, Full Armor Master, Nothung, Chaos Angel, Dis Pater) converting a board cleared by hand traps and removal; Garura / Mudragon fusion beats plus Draco Berserker via a single Blackwing or Bystial starter
• Turn 1 (going first): Normal Summon a Blackwing searcher (Sudri, Vata, Shamal) to fetch a Synchro material or Black Whirlwind, then build a Blackwing Synchro board while holding Ash Blossom and Droll for the opponent's first search or draw
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Nibiru, D.D. Crow and Infinite Impermanence in a six-card hand to stop the opponent's board, then Synchro Summon on the next turn
• Recovery: Blackwing and Bystial monsters return from the GY and banish zones via Bystial Druiswurm, Magnamhut, Baldrake, Twin Shadow and Black Feather Whirlwind; the card text supports recursion but no recorded lines confirm it
• After siding: Not available: the deck runs no side deck, so no post-side plan can be built from the evidence

Why it scores here

This is an illegal list: Ash Blossom & Joyous Spring is run three times against a limit of two, so the score is capped at 30 and the evaluation is structural only. The structural read comes from the system, not from averaging card scores. Blackwing searchers and Black Whirlwind give a fair chance of a live engine turn 1 (searcher text group P(at least one in a 5-card hand) ≈ 0.72, Inferred), and the 12 hand traps give strong going-second interaction (P(at least one hand trap in a 6-card hand) ≈ 0.79, Inferred). The deck is three archetypes stacked together (Blackwing 26, generic 25, Bystial 4, Kaiju 3, Mulcharmy 3, others), with 18 tech cards and no side deck, so bricks and conflicting hands are a real risk. No recorded boards exist, so the combo ceiling and median are text-only inference, and popularity or archetype share earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (structural weights from Midrange profile; D13 kept as provisional and excluded from Final). Structural ≈ 49, Going First ≈ 45, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Engine conflicts (-4); Illegal list cap (-13). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 47 before modifiers; engine conflicts -4 gives 43; illegal deck capped at 30 per rubric Step 2 (structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.72 · 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

• Strong going-second interaction: 12 hand traps, with P(≥1 in a 6-card hand) ≈ 0.79
• Blackwing searchers and Black Whirlwind give a real turn-1 chance (≈ 0.72 for a searcher in hand 5)
• Layered endboard interaction: Droll, Ash, Infinite Impermanence, Evenly Matched and Lightning Storm
• High-ceiling Synchro and Extra Deck bosses at 3000 to 3500 ATK

Weaknesses

• Illegal: Ash Blossom run at 3 copies against a limit of 2
• Three archetypes plus generic cards in one 55-card main deck: 70 off-archetype copies and 18 tech slots lower coherence
• No side deck: post-side adaptation is impossible
• No recorded boards, so the combo ceiling and median cannot be verified

Critical choke points

• Blackwing searchers (Sudri, Vata, Shamal) are the only route to a Synchro board on turn 1 going first
• Ash Blossom and Droll are the main answers to the opponent's first turn; losing them to a non-hand-trap plan leaves few answers

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is run 3 copies against a Semi-Limited limit of 2 (legality.violations); Main 55 and Extra 15 are within the OCG size rules; Side is 0 (legal range 0 to 15); Core cards Bystial Magnamhut, Droll & Lock Bird, Bystial Druiswurm, Mulcharmy Fuwalos and Ash Blossom are all present (usage statistics)
• Observed: No recorded boards exist (combo data total combos 0), so no board frequencies are observed
• Inferred: Searcher-text group P(≥1 in 5 cards) ≈ 0.72; Hand-trap group P(≥1 in 6 cards going second) ≈ 0.79; Engine conflicts and brick risk from three archetypes and 18 tech cards; Going-second interaction density from 12 hand traps
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit (archetype meta-share absent)
• 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 and starter rates) in YGOVN Meta Power is provisional unless a dated metagame sample is supplied deck title is null and no sideboard is listed
