Bystial/Byssted Deck #772982 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 60 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Cyber Dragon beatdown and Extra Deck boss pressure: Gustav Rocket (5000 ATK), Cyber Twin Dragon, Cyber Eternity Dragon and Carnot, all reached through the Cyber Dragon searchers and summons; Fusion and Link pressure through Chimeratech and Cyber Dragon Sieger, with Jizukiru as a high-ATK Kaiju beater
• Turn 1 (going first): Open with a Cyber Dragon Core or Cyber Emergency search to reach Cyber Dragon / Herz / Nachster, then extend into an Extra Deck boss; hold Ash Blossom or Ghost Belle for the first-turn negate
• Turn 2 (going second): Six-card hand with a hand trap (about 59% to hold at least one) to answer the opponent's first starter, then rebuild the Cyber Dragon line from the GY through Cyber Repair Plant and Cyberdark Realm
• Recovery: Cyber Repair Plant and Cyber Dragon GY recursion, Cyber Dragon Nova and Herz special-summon effects, and Cyberdark Chimera / Wurm to rebuild the board from the GY
• After siding: No Side Deck is registered (0 of a 0-15 allowance), so there is no post-side plan; best-of-3 play is unsupported by this list

Why it scores here

This is scored as a connected system, not as an average of its cards. The deck reliably reaches a Cyber Dragon searcher line: P(at least one searcher-text card in a 5-card opener) is about 0.84, and Cyber Dragon Core alone is about 0.23 per opener. Hand-trap and negation density is high (Ash Blossom, Ghost Belle, Infinite Impermanence, Solemn Accusation, Disablaster, Therion King Regulus), which lifts interaction and resilience, but the going-second hand-trap estimate is only about 0.59 and no recorded boards exist to confirm conversion. The main deck is inconsistent: 34 level-0 spells and traps, 14 single-copy slots, and 74 of 60 main slots off the listed archetype, so the Bystial label does not describe the list. Popularity and archetype usage did not earn points, because the core Bystial cards are absent. The deck is Illegal (Ash Blossom at 3 copies against a limit of 2), so the final score is capped at 35 and the result is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-6); no_side_deck (-3); dependence_on_extra_deck_boss (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*54 + 0.20*40 - 11 = 40; Illegal-deck cap (copy-limit violation) sets the reported score to 35 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.23 · 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: about 22 negation-text and 8 hand-trap cards
• Extra Deck bosses with high ATK and multi-attack or piercing text (Gustav Rocket, Twin Dragon, Eternity Dragon)
• Cyber Dragon searchers (Core, Emergency, Repair Plant) give about 84% searcher access in a 5-card opener

Weaknesses

• Illegal as listed: Ash Blossom is run at 3 copies against a limit of 2
• Archetype label mismatch: 0% exact-name purity; the Bystial core cards are absent
• Loose main deck: 34 level-0 cards and 14 single-copy slots reduce consistency
• No Side Deck registered, so there is no post-side plan

Critical choke points

• Cyber Dragon searchers and summons, which most lines depend on
• A single hand trap for the going-second opener (about 59% to hold one)
• Extra Deck material requirements for the Gustav, Twin Dragon and Eternity Dragon lines

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Ash Blossom & Joyous Spring is at 3 copies against OCG Semi-Limited limit 2; Main 60 / Extra 14 / Side 0; Main and Extra sizes are within the OCG rules; Card text for the listed cards (Ash Blossom, Ghost Belle, Impermanence, Solemn Accusation, Gustav Rocket, Cyber Twin Dragon); Usage stats: Bystial core cards (Magnamhut, Druiswurm, Droll & Lock Bird) are absent from this list
• Inferred: Cyber Dragon searcher access about 0.84 in a 5-card opener; Going-second hand-trap access about 0.59; Consistency penalty from 34 level-0 cards and 14 single-copy slots; Interaction density high, based on text and tags
• Provisional: Meta Power and matchup fit (no dated metagame sample or tournament link)
• 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 1 passcode (10443957) in the main deck list could not be resolved and was counted as main No win-rate telemetry (going first/second, matchup, brick/starter rates) Meta Power is Provisional without a dated metagame sample No Side Deck, so Side Deck adaptability is unassessed beyond the absence of a plan
