Bystial/Byssted Deck #770171 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link and Fusion boss monsters (Unchained Soul Lord of Yama, Unchained Abomination, Abominable Unchained Soul, Underworld Goddess) backed by Unchained Twins and Soul recursion from the GY; Bystial Druiswurm and Bystial Magnamhut 2500-ATK beaters, plus Luce the Dusk's Dark as a 3500-ATK fusion finisher
• Turn 1 (going first): Open on a Unchained starter (Tour Guide, Aruha, Sharvara, Abomination's Prison or a set trap), use Unchained searchers to find the next starter, then Link Summon into a boss monster while holding Ash Blossom or Impermanence for the opponent's response
• Turn 2 (going second): Hold a hand trap (Ash Blossom, Effect Veiler, Ghost Ogre, Infinite Impermanence) to break the opponent's first combo, then rebuild the board with Unchained recursion from the GY
• Recovery: Recover from a removed board by recycling Unchained Twins or Sharvara from the GY and re-searching with Abomination's Prison or Anguish's searcher effect
• After siding: No side deck is registered; a post-side plan cannot be evaluated from this list

Why it scores here

The deck opens reliably because roughly 12 to 16 Unchained starters (Tour Guide, Aruha, Sharvara, Abomination's Prison, Abominable Chamber, Escape of the Unchained) sit across four or more distinct entry points, so a functional hand is likely on the going-first turn (Inferred, P(at least one starter in 5) ≈ 0.85). Seven hand traps and about 18 removal or negation cards give it layered interaction on the opponent's turn and after a board is set, which carries most of the Structural score. Conversion is credited through the Link and Fusion boss pool, which reaches 2500 to 3500 ATK, rather than through any recorded combo, since the export contains no parseable boards. Usage popularity and archetype identity earned no points, the deck's copy counts for Limited cards (Magnamhut, Druiswurm, Feather Duster) were checked only for legality, and the score was built from the system's consistency, interaction, and finishing power, not from averaging card scores. The missing side deck and the absence of any dated meta sample hold the Final Contextual Score down.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary, not separately blended. Structural ≈ 63.6, Going First ≈ 66, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist_exposure (-2); no_side_deck (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), plus modifiers: 0.80*63.6 + 0.20*55 = 61.9, then -2 banlist modifier = 59.9, rounded to 60

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense starter set with several distinct entry points
• Strong interaction stack: 7 hand traps plus removal and negation text
• Link and Fusion boss pool with 2500 to 3500 ATK bodies
• Multiple recursion paths from the GY (Unchained Twins, Sharvara, Sarama)

Weaknesses

• No side deck, so no best-of-3 adaptation
• Several cards are single copies with Limited status, creating single-point failures
• Multi-step Unchained chaining raises pilot error risk
• No parseable combo data to confirm the realistic ceiling or median

Critical choke points

• Abomination's Prison and Tour Guide as the main searchers for the Unchained engine
• Bystial Magnamhut and Druiswurm as the only Bystial beaters (1 copy each)
• Extra Deck link monsters that depend on Unchained material

Recommended changes

Evidence & confidence

• Verified: Legal OCG list: 40 main, 15 extra, 0 side; restricted copies are at legal limits; Card text for 23 distinct main and 11 distinct extra cards; Usage stats: 3 of 5 archetype core cards present (Magnamhut, Druiswurm, Ash Blossom at 2 copies)
• Observed: Usage popularity of the archetype core confirms this is a real, accessible build
• Inferred: Starter access ≈ 0.85 in opening hand 5 (Inferred hypergeometric estimate); Hand-trap group ≈ 0.71 in hand 6 going second; Going-first and going-second power estimates
• Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck registered, so post-side behaviour cannot be scored
