Bystial/Byssted Deck #770291 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link-monster board pressure (Perfectron Hydradrive Dragon, Firewall Dragon Darkfluid, Bystial Druiswurm/Magnamhut, Maliss Link monsters) converted after the opponent's plays are interrupted; Maliss Link recursion and banish-based Maliss loops (text-only, no recorded boards)
• Turn 1 (going first): Open a Link-capable starter (Dotscaper, Cyberse Wicckid, Backup or Wizard @Ignister, Maliss White Rabbit) with a searcher and keep 1-2 hand traps up for the opponent's first activation; Link into a 2-3 link board
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Droll & Lock Bird / Infinite Impermanence to blank the opponent's starter, then use Bystial Druiswurm or Magnamhut from the GY or hand to rebuild a board
• Recovery: Maliss Traps and Mulcharmy draw effects refill the hand; Cynet Mining and Terraforming search Level 4 Cyberse or Field Spells; GY Link monsters return via Maliss and Transcode Talker effects
• After siding: Not evaluable: the side deck is empty (0 cards), so there is no post-side plan

Why it scores here

This list is Illegal in OCG: Link Decoder is Forbidden and Maliss in Underground is run three copies against a limit of two, so the score is capped and labelled theoretical/structural-only. Structurally, the deck has a real Link-based plan (14 Link monsters, Perfectron and Firewall Dragon Darkfluid as closers) and a dense interaction suite (12 hand traps, 15 negation-text cards, 23 removal-text cards) that gives it a good going-second hand-trap profile (about 78% chance of at least one hand trap in a six-card hand, Inferred). Engine accessibility and median output are only moderate: the archetype core is spread across Bystial, Maliss, Ignister, Cyber and Mulcharmy sub-archetypes with 71 off-archetype copies and no exact-name purity, and there are no recorded boards to measure a floor or ceiling. The score comes from consistency, interaction and going-second pressure on the system, not from the popularity of Bystial/Byssted (usage stats only confirm the core is real) and not from averaging the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun weights not blended (no separate Stun-only score computed). Structural ≈ 51, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist/copy-limit exposure (-10); engine conflicts (-2). Final formula: Illegal cap applied: Final = min(0.80*Structural + 0.20*TournamentReliability + Modifiers, 30) = min(0.80*51 + 0.20*40 - 12, 30) = 30; Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.55 · 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: 12 hand traps, 15 negation-text cards and 23 removal-text cards
• Strong Link closers (Perfectron Hydradrive Dragon 5000 ATK, Firewall Dragon Darkfluid 3000 ATK) with recursion via Maliss and Bystial
• Good going-second hand-trap density (≈78% at least one in opening 6, Inferred)
• Multiple searchers (8 searcher-text cards) support hand consistency

Weaknesses

• Illegal in OCG: Link Decoder is Forbidden and Maliss in Underground exceeds its copy limit
• No side deck, so no post-side adaptability
• Three-plus archetype families compete for the same slots, lowering engine coherence
• Off-archetype density is high (71 copies, 0% exact-name purity)
• Many single-copy Limited cards make the list fragile to any banlist change

Critical choke points

• Maliss Link monsters and their banish-based recursion depend on a small set of Maliss staples (Maliss

  Chessy Cat, Maliss White Binder)

• Opening-hand starter access is only about 55% for the core archetype (Inferred)
• Bystial Druiswurm and Magnamhut are single copies Limited to one, so losing either removes the Bystial recursion route

Recommended changes

Evidence & confidence

• Verified: Illegal status: Link Decoder Forbidden, Maliss in Underground 3 copies against a legal limit of 2; Main 56, Extra 15, Side 0 within size rules (except the side deck is empty); 12 hand traps, 15 negation-text and 23 removal-text cards by role tag; 14 Link monsters and 1 Fusion monster in the Extra Deck; Archetype core copies = 8; 0 exact-name archetype copies, 71 off-archetype
• Observed: Core archetype usage stats: Bystial Magnamhut 84.8%, Droll & Lock Bird 60.9%, Bystial Druiswurm 60.9% (usage sample)
• Inferred: Opening-hand starter access ≈ 0.55 (core archetype, hand 5); Hand-trap group ≈ 0.78 at least one in opening 6 (going second); Engine conflicts reduce consistency; Going-second pressure from hand traps is above going-first pressure
• Provisional: Meta Power (no dated metagame sample); Format fit and matchup coverage (D13); Tournament reliability (no tournament link or per-pilot record)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry for going-first/second, matchup or brick rate no side deck: post-side plan cannot be evaluated Meta Power is Provisional unless a dated metagame sample is supplied
