Bystial/Byssted Deck #772720 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Fusion-summon 8-level Dragon bosses (Albion the Branded Dragon is the intended engine, but it is Forbidden here, so the realistic bosses are Mirrorjade, Titaniklad, Lubellion, Rindbrumm, Alba-Lenatus, and The Dragon that Devours the Dogma); Synchro pressure via The Three Champions of Swordsoul and Ecclesia and the Dark Dragon (only 2 Synchros, so this is a minor line)
• Turn 1 (going first): Turn 1 Nadir Servant / Mistaken Arrest / Dominus Spark-style setup is not evidenced; the realistic opener is a Normal Summon of Fallen of Albaz or Blazing Cartesia, or a Branded Fusion / Branded Opening search, into a Fusion Summon. Hand-trap reliance (Ash, Droll, Effect Veiler) is available but the list runs them at illegal counts.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit, Effect Veiler, Droll & Lock Bird, and Nibiru as hand traps against the opponent's first summon or search, then rebuild through Fallen of Albaz and Fusion bosses from the Extra Deck.
• Recovery: Recursion through Fallen of Albaz (Graveyard Fusion Summon), Dogmatika Ecclesia, and Branded Retribution from the GY; no recorded recovery lines exist in the evidence.
• After siding: Not evaluable: Side Deck size is 0, so there is no post-side plan.

Why it scores here

The list is illegal in OCG: five cards are over their Limited or Semi-Limited copy caps and two are Forbidden, so the score is capped at 20 and the evaluation is structural only. Structural power is about 44 on a Midrange weighting, from a legal-size Main Deck (56 cards) whose searcher text (80% chance of at least one in an opening 5) and 13 hand traps give interruption and going-second strength. The engine is weakened by 71 off-archetype copies, a Forbidden Albion core, and no side deck. Floor and median output cannot be assessed because no combos were recorded, and no win-rate, matchup, or tournament data exists. The score comes from consistency, interaction, and structure on the system, not from averaging card scores or from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 44, Going First ≈ 40, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); no Side Deck (-4); illegal_cap (0). Final formula: No reliable metagame: 0.80*Structural(44) + 0.20*TournamentReliability(35) = 42, then context modifiers (-12) = 30, then Illegal legality cap = 20 (theoretical/structural-only; no normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · 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: 13 hand traps and 12 negation-text cards give strong going-second disruption
• Searcher density (15 cards) keeps the opening hand functional at about 80%
• Fusion Extra Deck offers several 8-level bosses at 2500–3000 ATK

Weaknesses

• Illegal in OCG: 5 cards over their copy limit and 2 Forbidden cards (Albion, Called by the Grave)
• 71 off-archetype copies dilute the Bystial/Byssted and Branded engine
• No side deck, so no post-side adaptation
• No recorded combos, so the floor and median output cannot be verified

Critical choke points

• Albion the Branded Dragon is Forbidden and is the intended engine core; without it the Branded line loses its main route
• Fallen of Albaz is the single Dogmatika/Albaz hub for both Fusion and recursion

Recommended changes

Evidence & confidence

• Verified: Main 56, Extra 15, Side 0; OCG size rules are satisfied; Copy-limit violations and banlist statuses for 7 cards (Albion and Called by the Grave Forbidden; five Limited or Semi-Limited); Archetype spread: 71 off-archetype copies; 0 exact-name purity; Usage stats: Bystial Magnamhut (85.6%) and Bystial Druiswurm (59.9%) are core cards missing from this deck
• Inferred: Opening-hand hypergeometric estimates (searcher ~0.80, hand-trap ~0.81 going second); Interaction density and going-second strength from text read; Brick and conflict risk from off-archetype mix and hand-trap count; Interruption resilience from repeated hand-trap and restart text
• Provisional: Meta power (no dated metagame sample); Matchup and format fit (no tournament context)
• 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 deck title is null, so the deck is identified only by its ID and archetype guide snippets are short and carry no section structure no side deck, so no post-side evaluation is possible
