Bystial/Byssted Deck #750912 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Extra Deck boss pressure from Link and Xyz monsters (Phantom Fortress Enterblathnir, Super Starslayer TY-PHON, Hraesvelgr) after Radiant Typhoon board development; Bystial Magnamhut recursion with Dragon monsters for extra pressure
• Turn 1 (going first): Open Radiant Typhoon / Mulcharmy starters, use Mystical Space Typhoon to clear backrow and trigger Radiant Typhoon Quick-Play recursion, then link into a boss monster
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird and Solemn Judgment to interrupt the opponent's search and summon chain before committing to the Radiant Typhoon board
• Recovery: Radiant Typhoon searchers and Quick-Play recursion (Ascendance, Manifestation, Chant) rebuild the hand after a hand-trap or negation
• After siding: Not evaluable: the deck has no Side Deck (0 cards), so there is no post-side plan

Why it scores here

The deck opens its Radiant Typhoon engine reliably through a dense set of searchers (18 searcher-text cards; about 87% chance of at least one in an opening 5), with Mystical Space Typhoon acting as the recursion hinge. Its interaction is broad, with hand traps and negation layered across both turns, which lifts the end-board and interaction scores. Conversion is the weak point: no combo boards were recorded, so the ceiling and median come only from text inference and stay moderate. The score is capped low because the list is illegal (five copy-limit violations including two Forbidden cards and a Forbidden Called by the Grave), so it is theoretical and structural only. Popularity and archetype-usage signals were not used to add points, and card scores were not averaged into the deck result.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 42, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-8); Weak post-side plan (-3). Final formula: No reliable metagame: 0.80*Structural(50) + 0.20*TournamentReliability(45) = 49 raw; modifiers -11 give 38; Illegal deck capped to 20, theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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 searcher and recursion package for the Radiant Typhoon engine
• Layered negation and removal (Ash, Droll, Solemn, Dominus Purge, Evenly Matched) across both turns
• Extra Deck covers several boss routes (Link, Xyz, Synchro)

Weaknesses

• Illegal list: five copy-limit violations including two Forbidden cards
• Main Deck at 55 cards with 27 distinct cards dilutes consistency
• No Side Deck, so no post-side plan
• No recorded boards, so conversion cannot be verified

Critical choke points

• Mystical Space Typhoon is the recursion hinge for multiple Radiant Typhoon cards
• Dependence on Radiant Typhoon searchers to find the engine starter

Recommended changes

Evidence & confidence

• Verified: Legality: five copy-limit violations including Forbidden cards; Main 55 / Extra 15 / Side 0 counts; Card text for the Radiant Typhoon engine and interaction cards
• Observed: Core archetype cards present: 5 of 7 (71.4%) usage-listed core cards
• Inferred: Starter P(≥1 in opening 5) ≈ 0.25 for 3-copy starters; searcher P ≈ 0.87; Interaction density and resilience read from text; Going-first and going-second estimates
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta share and pilot match record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power provisional without a dated metagame sample Side Deck empty: no post-side evaluation possible
