Bystial/Byssted Deck #750923 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 15/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 12 violation(s).

Identity & game plan

• Win condition: Synchro beatdown from the Elfnote and Angelechy Extra Deck bodies (Elfnote June Pride, Angelechy Shatranga, Angelechy Bastion, Vidolium-free boards), backed by hand-trap disruption; Chaos Angel and Ancient Fairy Dragon as board-removal and recursive follow-up on the going-second turn
• Turn 1 (going first): Open with Elfnote searchers and Angelechy starters from hand, extend into a Synchro on turn 1 with the centre-zone monster, and hold Ash Blossom or Droll for the opponent's first attempted search
• Turn 2 (going second): Use the six-card hand's hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Ghost Belle & Haunted Mansion, D.D. Crow, Droll & Lock Bird) to break the opponent's starter, then convert the surviving Elfnote monsters into a Synchro
• Recovery: Mulcharmy Fuwalos and Mulcharmy Purulia draw cards when the hand is empty, and Elfnote Regina and Elfnote Power Patron re-enter the board from the hand or Graveyard
• After siding: No Side Deck is registered, so no post-side plan exists for a best-of-3 event

Why it scores here

The deck's structural score comes from the system: a searcher-dense Elfnote and Angelechy engine (P(at least one searcher in a 5-card opening hand) ≈ 0.83, Inferred), with 11 hand traps that give it real disruption on the going-second turn (P(at least one hand trap in a 6-card hand) ≈ 0.76, Inferred), and Mulcharmy draw engines that recover an empty hand. The score is held back by a 0% exact-archetype purity: 71 of 74 copies belong to off-archetype or generic cards spread across Elfnote, Angelechy and Mulcharmy, which weakens engine coherence. No combos were supplied, so the ceiling and median dimensions (D3, D4) are text-only inference and carry low weight. The deck is Illegal: it runs 7 Forbidden cards and several Limited or Semi-Limited cards over their copy limits, and its Extra Deck has 16 cards against a maximum of 15. Under the rubric the Illegal status caps the final score, so 15 is a capped theoretical value, not a normal Final Contextual score. Popularity was not credited: archetype usage stats confirm the core is real, and nothing was averaged from card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 52, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12); illegal cap (-23). Final formula: Illegal cap applied. Uncapped: 0.80*Structural(52) + 0.20*TournamentReliability(40) + banlist modifier(-12) ≈ 38; capped to 15 under the Illegal-status rule. Meta Power is 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

• Dense searcher text (16 searcher effects) supports consistent Elfnote and Angelechy access
• Eleven hand traps and interaction layers give real disruption on the going-second turn
• Mulcharmy draw effects and Elfnote Regina recursion recover from an empty hand
• High-ATK Synchro bodies such as Vidolium, June Pride and Shatranga give closing power on paper

Weaknesses

• Illegal in TCG: Forbidden cards and copy-limit violations must be removed before the list is playable
• 0% exact-archetype purity: engines from Elfnote, Angelechy and Mulcharmy compete for the same slots
• No Side Deck, so best-of-3 adaptation is impossible
• Extra Deck of 16 cards exceeds the 15-card limit

Critical choke points

• Elfnote Tinia (Forbidden, 3 copies) is a key engine card that cannot be legally run
• Single-copy Synchro bosses (Chaos Angel, Ancient Fairy Dragon) are the only board-breaking follow-up

Recommended changes

Evidence & confidence

• Verified: Main deck 55 cards and Extra Deck 16 cards against size rules of 40-60 and 0-15; Eleven copy-limit violations and seven Forbidden cards in the TCG banlist; Card stats, types and text from the resolved card table; Usage stats: Bystial Magnamhut 100%, Mulcharmy Fuwalos 94%, Ash Blossom 88%
• Inferred: P(at least one searcher in a 5-card opening hand) ≈ 0.83; P(at least one hand trap in a 6-card going-second hand) ≈ 0.76; Consistency and brick estimates from hypergeometric draw odds; Interaction layering from card text and role flags
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no 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 no win-rate telemetry; going-first, going-second and matchup results are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck registered; post-side evaluation is not possible
