Bystial/Byssted Deck #773072 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 53 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz pressure from DoomZ XII / XIII / Jupiter and Vidolium (5000 ATK Pendulum) once a Power Patron or DoomZ starter has opened the board; Bystial Magnamhut (2500 ATK) and Gigantic Sargas as beatsticks after the hand-trap layer has cleared the opponent's interaction
• Turn 1 (going first): Open a starter from Ash/Ghost Belle/Ghost Ogre-protected hands, then extend into a DoomZ Xyz (DoomZ Break or Drastrius) while holding hand traps for the opponent's first response
• Turn 2 (going second): Use the hand-trap layer (Infinite Impermanence, Ash, Droll, Ghost Ogre, Ghost Belle, Evenly Matched, D.D. Crow) to break the opponent's starter, then rebuild through Mulcharmy draws
• Recovery: Recover through DoomZ searchers (Raiders, Change, Amalthe, Medius) and Mulcharmy draws; the Extra Deck is the limiting factor because it is over the legal size
• After siding: Not evaluable: the Side Deck is empty (0 cards), so the deck has no adaptation plan for best-of-3 play

Why it scores here

This list is Illegal in OCG: the Extra Deck holds 17 cards against a limit of 15, and it runs 3 copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of 2. Under the rubric it is capped low and treated as a structural-only read. Its strengths are real: 15 hand traps and 12 negation-text cards give the going-second layer strong coverage (P(at least one hand trap in a 6-card opening) ≈ 0.88), and the DoomZ searchers plus Mulcharmy draws give good card access. Its weaknesses are the DoomZ core, which is only about 52% likely to be open in a 5-card hand because of 7 core copies, plus a Side Deck of 0 cards and no recorded combos to show the real conversion. The score is built from the deck's system properties and was not averaged from individual card scores. Archetype popularity (Bystial/Byssted is in the usage stats) confirms the deck is real, but it did not add points.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun secondary (structural weights from the Midrange profile; the Stun profile was not blended in). Structural ≈ 42, Going First ≈ 35, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-6); dependence on Extra-Deck cards (-3); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); (0.80*42.3 + 0.20*35 = 40.9) then the modifiers (−11) and the Illegal cap at 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.26 · key two-card combo ≈ — · full-brick estimate ≈ 0.48 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 15 hand traps and 12 negation-text cards give the going-second layer strong coverage
• 19 searcher-text cards and Mulcharmy draws give card access and recovery
• High-ATK Xyz/Pendulum closers (Vidolium 5000, Jupiter 3500, Drastrius 2700)

Weaknesses

• Illegal in OCG: Extra Deck at 17 (limit 15) and Ash at 3 copies (limit 2)
• The DoomZ core is open in only about half of 5-card hands
• Side Deck is empty, so there is no post-side plan
• No recorded combos or tournament data to verify conversion

Critical choke points

• Extra-Deck legality: the 17th Extra card has to go before the deck can be played in OCG
• The 4 Xyz Monsters and Power Patron/DoomZ starters are single-line dependencies if the opponent breaks the starter

Recommended changes

Evidence & confidence

• Verified: Illegal status: Extra 17 > 15, and Ash run at 3 copies against a legal limit of 2; Banlist: Harpie's Feather Duster, Prohibited Power Patron Portal - Terminus, Bystial Magnamhut, Droll & Lock Bird, and Solemn Judgment are Limited at 1 copy each (legal); Hand-trap count 15, negation-text 12, searcher-text 19, removal-text 34, Side Deck 0; Usage stats: Bystial Magnamhut 84.6%, Droll & Lock Bird 62.6%, Mulcharmy Fuwalos 60.2%, Ash 56.9%; Bystial Druiswurm (61%) is missing
• Inferred: Hypergeometric starter, core, and hand-trap odds from the Main Deck; Strategy classification as Midrange with Stun and Toolbox secondaries; Going-second hand-trap coverage; Structural dimension scores from card text and composition
• Provisional: Meta Power (null), since no dated metagame sample was supplied; Matchup fit (D13), which is only the archetype's share
• Data gaps: no combos supplied; combo floor, median, and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry (going first/second, matchup, brick/starter rates) Side Deck is empty (0 cards), so post-side adaptation is unmeasured Meta Power is Provisional without a dated metagame sample deck title is null
