Bystial/Byssted Deck #773492 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 54 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Blue-Eyes and Stardust synchro/fusion bosses (Blue-Eyes Ultimate Spirit Dragon, Neo Blue-Eyes Ultimate Dragon, Stardust Sifr, Indigo-Eyes) backed by Blue-Eyes White Dragon; Mulcharmy draw-and-hand-size pressure (Fuwalos, Purulia) and Primite recursion/searching
• Turn 1 (going first): Normal Summon a Level 1 Tuner (Sage with Eyes of Blue, Maiden of White, Master with Eyes of Blue) or Primite Lordly Lode to search the Blue-Eyes/Primite pieces, then Synchro or Fusion into a Blue-Eyes boss; the list has no combo boards recorded, so this is a structural read (Inferred)
• Turn 2 (going second): Use hand traps and backrow/Spell answers (Ash Blossom, Ghost Belle, Infinite Impermanence, Nibiru, Skull Meister, Droll & Lock Bird, Solemn Judgment, Harpie's Feather Duster, Lightning Storm) to disrupt the opponent, then rebuild through searchers (Wishes for Eyes of Blue, Mausoleum of White) (Inferred)
• Recovery: Searchers and GY recursion: Master with Eyes of Blue and Wishes for Eyes of Blue return Tuners from GY; Ash Blossom and Ghost Belle can be discarded for negation and remain bodies for Synchro material (Inferred)
• After siding: None: the deck runs zero Side Deck cards, so there is no post-side plan and best-of-3 adaptation is not possible as listed

Why it scores here

The score is not an average of card scores and does not reward the Bystial/Byssted label or popularity: the list contains only 2 Bystial cards and no exact-name archetype cards, so the archetype tag describes a Blue-Eyes/with Eyes of Blue/Primite/Mulcharmy blend rather than a coherent engine. The system opens reasonably well (the 15-card searcher group gives about 0.82 chance of at least one in a 5-card opening, Inferred), and the interaction suite (17 hand-trap and tech flags, Solemn Judgment, Harpie's Feather Duster, Lightning Storm, Dragon's Mind) gives it real going-second disruption and end-board control. Its closing threats are large (Blue-Eyes Ultimate Spirit Dragon 3500 ATK, Neo Blue-Eyes Ultimate Dragon 4500 ATK, Stardust Sifr 4000 ATK), but no recorded boards exist, so combo floor, median and ceiling are text-only and carry low confidence. The list is illegal (Ash Blossom & Joyous Spring at 3 copies against a limit of 2) and has no Side Deck, so the structural score is pre-cap and the final score is capped at 35 as a theoretical, structural-only read.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 54.6, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: No Side Deck (-4); Banlist/copy-limit exposure (-4). Final formula: Illegal list: no normal Final issued. Pre-cap value = 0.80*Structural(54.6) + 0.20*TournamentReliability(40) + modifiers(-8) = 43.7; theoretical cap applied to 35 (structural-only read). Meta Power null (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 interaction suite: hand traps, Spell/Trap answers and Lightning Storm
• Large synchro and fusion bosses reach 3500-4500 ATK
• Searcher-text density gives high opening access (Inferred)

Weaknesses

• Illegal as built: Ash Blossom & Joyous Spring over the copy limit
• No Side Deck, so no best-of-3 adaptation
• Archetype label Bystial/Byssted does not match the list (2 Bystial cards, 0 exact-name cards); 69 off-archetype copies
• No recorded boards, so combo ceiling and floor are unmeasured

Critical choke points

• Blue-Eyes White Dragon and Synchro/Fusion boss access depends on Tuner and searcher lines that run through a few single-copy cards
• Ash Blossom over-limit: removing one copy is required before the list is legal

Recommended changes

Evidence & confidence

• Verified: Main 54, Extra 15, Side 0 are within TCG size rules; Ash Blossom & Joyous Spring: 3 copies run, legal limit 2 (Semi-Limited); All other restricted cards are run at legal copy counts (Limited cards at 1 copy); Extra Deck split: Synchro 9, Link 3, Fusion 2, XYZ 1; Archetype purity 0% exact-name; 69 off-archetype copies
• Inferred: Opening access estimate: P≥1 searcher in opening 5 ≈ 0.82; Going-second hand-trap availability ≈ 0.91; Interaction and board-breaking strength from card text; Blue-Eyes/Primite engine coherence read from sub-archetype spread
• Provisional: Meta Power (no dated metagame sample); Matchup fit and tournament reliability (no tournament link)
• 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 Archetype label 'Bystial/Byssted' does not match the list composition (2 Bystial cards, 0 exact-name cards); the deck's real engine is Blue-Eyes/with Eyes of Blue/Primite/Mulcharmy No Side Deck cards are listed Deck title is null
