Bystial/Byssted Deck #772899 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: FIRE Dragon engine (Tenpai/Sangen) feeding Bystial Dis Pater, Sangenpai Transcendent Dragion and Trident Dragion boss monsters (Inferred from card text); Link Charmer and Synchro beatsticks as follow-up pressure (Inferred)
• Turn 1 (going first): Open a Tenpai/Dora Dora searcher line and hold hand traps for the opponent's first interaction (Inferred)
• Turn 2 (going second): Use the 12 hand traps to break the opponent's first board, then rebuild through Tenpai and Sangen searchers (Inferred)
• Recovery: Re-search Tenpai Dragon monsters with Sangen effects and Paidra/Fadra, then re-enable Synchro/Link summons (Inferred)
• After siding: None: the deck runs no Side Deck, so there is no post-side plan (D12 = 15)

Why it scores here

The deck is scored as a system, not by averaging its 55 off-archetype card copies or any card score. Its Tenpai/Sangen searchers (about 78% chance of at least one searcher in a 5-card opening hand, Inferred) give it a reasonable chance of a live start, and its 12 hand traps and layered negates give real interruption resilience and strong going-second interaction (about 90% chance of at least one hand trap in a 6-card hand, Inferred). Its closing power comes from 3000-3500 ATK Synchro boss monsters, but there is no recorded combo evidence, so the median and ceiling are text-only inference. Popularity earns no points: the archetype usage stats only confirm the list is a real build, and the deck has 0% exact archetype purity and no side deck. The list is Illegal because Ash Blossom & Joyous Spring is run 3 copies against a Semi-Limited limit of 2, so the structural score of about 52 is theoretical only and the final score is capped at 25.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Copy-limit violation (-5); No side deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + modifiers (-8) = 43.6, capped at 25 because legality is Illegal; theoretical/structural-only, Meta Provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · 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

• Layered hand traps and negates (12 hand traps, 12 negation-text cards) give strong interruption and going-second interaction
• High-ATK Synchro bosses (Bystial Dis Pater 3500 ATK) give closing power
• Clean 40-card main deck legal in size and within limits for every card except Ash Blossom

Weaknesses

• Illegal copy count: 3 Ash Blossom & Joyous Spring against a limit of 2
• Low archetype purity: 0% exact name, 55 off-archetype copies across Tenpai, Sangen, Charmer, Forbidden and Cyclone
• No side deck, so no post-side adaptability
• No combo evidence, so consistency and ceiling are inferred from text only

Critical choke points

• Tenpai/Sangen FIRE Dragon searchers: the engine depends on a small number of searchers (10 searcher-text cards) to go live
• Ash Blossom copy count is the first legality blocker; the deck cannot be played as built

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 are within OCG size rules; Ash Blossom & Joyous Spring: 3 copies run, legal maximum 2 (Semi-Limited); All other Limited cards run at 1 copy (legal); Card text and stats for all 37 listed cards
• Inferred: P(at least one searcher in 5-card hand) ≈ 0.78; P(at least one hand trap in 6-card hand) ≈ 0.90; Engine and boss-monster route read from text; Dimension scores D1 through D14
• Provisional: Meta Power is null; D13 is provisional with no dated meta sample; Usage stats (Droll & Lock Bird, Mulcharmy Fuwalos) are context only
• 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/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied deck title is null in the export
