Bystial/Byssted Deck #773100 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Granguignol, The Dragon that Devours the Dogma, Hyperinvoked Aeon, Titaniklad) reached through Fallen of Albaz and Branded/Fusion starters, with hand-trap protection; Ecclesia/Despia Synchro and Fusion pressure (The Three Champions of Swordsoul, Ecclesia and the Dark Dragon, Despian Quaeritis)
• Turn 1 (going first): Open Pot of Sloth or a Fusion/Branded starter, search Fallen of Albaz or a Tuner, and convert into a Level 8 Fusion or Synchro boss while holding hand traps for the opponent's first activation
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Droll & Lock Bird as interaction, then use Nibiru, Mulcharmy or Ecclesia to answer the board and rebuild a Fusion boss
• Recovery: Recover through Mulcharmy Fuwalos draw, Fallen of Albaz and the Ecclesia/Despia GY revival effects, and Mistaken Arrest to slow the opponent's searches
• After siding: Not evaluable: the deck has no side deck, so no post-side plan exists in the evidence

Why it scores here

The deck's structural read is moderate: it has a searcher-dense Fallen of Albaz and Branded/Fusion line that reliably reaches a Level 8 boss (P of at least one searcher in an opening 5 is about 0.83, Inferred), and 13 hand traps plus 9 negation-text cards give it strong interaction on the going-second turn (about 0.81 chance of at least one hand trap in a 6-card hand, Inferred). The system is weakened by the core Bystial engine being absent (Bystial Magnamhut and Bystial Druiswurm are missing, which the usage data shows as high-inclusion cards), by a main deck spread across roughly 16 sub-archetypes (only 34 generic and 0 exact-name archetype copies, so 0% exact purity), and by having no side deck at all. No combo boards were recorded, so the floor, median and ceiling are text-only inferences. Popularity and archetype usage were not counted as power, and the score is not an average of card scores. Because the list is Illegal (Kashtira Fenrir is Forbidden in OCG, and three other cards exceed their copy limits), the normal Final Contextual score does not apply, so the final value is capped at 25 and the evaluation is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); no side deck and engine conflicts (-4). Final formula: Illegal list: normal formula not applied. Raw no-meta value = 0.80*52 + 0.20*35 + modifiers(-12) = 37, then capped at 25 for Illegal status. Meta Power provisional/null.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · 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

• Level 8 Fusion and Synchro boss access from Fallen of Albaz and Branded starters
• 13 hand traps and 9 negation-text cards give strong going-second interaction
• High Extra Deck boss ceiling (Hyperinvoked Aeon 3800 ATK, Dogma 3000 ATK)

Weaknesses

• Illegal in OCG: Kashtira Fenrir is Forbidden and four cards exceed copy limits
• No side deck, so no post-side adaptability
• Core Bystial engine absent (Magnamhut and Druiswurm missing)
• Mixed archetype identity with 0% exact-name purity and many conflicting summon restrictions

Critical choke points

• Fallen of Albaz as the sole route to the Level 8 Fusion and Synchro bosses
• Hand-trap density on the going-second turn, with no side plan to fix a bad matchup

Recommended changes

Evidence & confidence

• Verified: Illegal status: Kashtira Fenrir Forbidden at 3 copies, four copy-limit violations; Main 56 and Extra 15 are within OCG size rules; Side is 0; Composition: 13 hand traps, 16 searcher-text, 9 negation-text, 19 removal-text; Usage: Bystial Magnamhut and Druiswurm are high-inclusion core cards missing from this list
• Inferred: Opening-hand probabilities (searcher about 0.83, hand trap about 0.81) are hypergeometric estimates from the deck list; Going-second interaction and boss conversion are read from card text
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot match record are absent no win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied No side deck is recorded for a best-of-3 OCG list
