Bystial/Byssted Deck #774109 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 54 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Blue-Eyes/Stardust/Blue-Eyes Ultimate-family Extra Deck boss monsters (Neo Blue-Eyes Ultimate Dragon, Blue-Eyes Ultimate Spirit Dragon, Stardust Sifr) backed by Blue-Eyes White Dragon and Blue-Eyes searchers; Bystial Druiswurm and Bystial Magnamhut 2500-ATK beaters with hand-trap protection
• Turn 1 (going first): Normal Summon a Level 1 Tuner searcher (Sage/Master with Eyes of Blue) or Primite Dragon Ether Beryl, search Blue-Eyes White Dragon, then build toward a Synchro/Fusion boss while holding hand traps for the opponent's first interaction
• Turn 2 (going second): Use Ash Blossom, Ghost Belle, Infinite Impermanence, Droll & Lock Bird, Nibiru and D.D. Crow to stop the opponent's first board, then rebuild through Blue-Eyes searchers and a Synchro/Fusion boss
• Recovery: Draw-trigger monsters (Mulcharmy Fuwalos/Purulia) and Blue-Eyes GY recursion (Master with Eyes of Blue, Maiden of White, Neo Kaiser Sea Horse) rebuild from an empty field
• After siding: No Side Deck: no post-side plan can be evaluated

Why it scores here

This list is Illegal: three copies of Ash Blossom & Joyous Spring exceed its Semi-Limited limit of two, so it receives a capped, structural-only score of 30 rather than a normal contextual score. Its structural read (58) comes from the system, not from averaging card scores: the Blue-Eyes and Primite searchers reliably reach a starter (P(at least one of 15 archetype-core cards in a 5-card opening hand) ≈ 0.82, Inferred), and seventeen hand traps and negates give the list a strong answer to a going-second opponent's first board (P(at least one hand trap in a 6-card hand) ≈ 0.91, Inferred). Its conversion ceiling is supported by Neo Blue-Eyes Ultimate, Blue-Eyes Ultimate Spirit and Stardust Sifr, but no recorded boards exist, so the median and floor are inferred from text and remain weak. The main deck splits across Blue-Eyes, Primite, Mulcharmy, Bystial and Stardust sub-engines with no Side Deck, which lowers efficiency, pilotability and post-side adaptability. Popularity or archetype usage did not earn points, and Meta Power stays null because no dated metagame sample was supplied.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58, Going First ≈ 58, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-6); no_side_deck (-4). Final formula: Illegal cap applied: raw 0.80*Structural(58) + 0.20*TournamentReliability(45) + Modifiers(-10) = 45, capped to 30 (Illegal; theoretical/structural-only). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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 engine access through Blue-Eyes/Primite searchers (~0.82 starter presence in opening 5)
• Seventeen hand traps and negates give strong going-second interaction
• Layered end-board negates and high-ATK Extra Deck bosses

Weaknesses

• Illegal copy count on Ash Blossom & Joyous Spring (3 vs 2)
• Five Limited/Semi-Limited cards concentrate banlist exposure
• Several unrelated sub-engines (Primite, Mulcharmy, Bystial, Stardust) reduce coherence
• No Side Deck and no combo data to evaluate median output

Critical choke points

• Blue-Eyes White Dragon as the main engine piece: few non-Blue-Eyes outs
• Single-copy Limited Bystial and Droll & Lock Bird reduce redundancy

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Ash Blossom & Joyous Spring run 3 copies, legal limit 2; Main deck 54 cards and Extra deck 15 cards are within TCG size rules; Side Deck is 0; Five Limited/Semi-Limited cards are present, each run at their legal limit; Card stats and text as listed in evidence (ATK/DEF, Extra Deck types)
• Observed: Archetype core presence: 9 of 9 core cards present (usage_statistics)
• Inferred: Starter access ≈0.82 at 5-card opening hand (hypergeometric, Main Deck only); Hand-trap presence ≈0.91 at 6-card going-second hand; Going-second interaction density from hand-trap and negate text; Conversion ceiling from text: Neo Blue-Eyes Ultimate, Blue-Eyes Ultimate Spirit, Stardust Sifr
• Provisional: Meta and matchup fit (no dated metagame sample, no tournament link); Tournament reliability (no win-rate or brick telemetry)
• 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, brick/starter/OTK rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck supplied — post-side adaptability unscored
