Stardust Bystial Deck #765761 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Tempo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro beatdown through Synchro bosses (Elfnote Seraphim Strelitzia, Vidolium, Accel Synchro Stardust Dragon, Elfnote June Pride), enabled by the Elfnote/Power Patron searcher engine (Inferred); Hand-trap and removal-backed tempo: Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird and Infinite Impermanence protect the engine and slow the opponent (Inferred)
• Turn 1 (going first): Open on an Elfnote/Power Patron searcher (Power Patron, Lucina, Regina, Tinia, Junoldo, Medius) to a Synchro-ready board; hold hand traps for a functional opposing turn (Inferred)
• Turn 2 (going second): Hold 2-3 hand traps and a Synchro starter; interrupt the opponent's first board, then rebuild with Elfnote/Power Patron searches (Inferred)
• Recovery: Searchers (17 searcher-text cards) and Medius/Portal recursion rebuild the starter after a hand-trap or removal exchange (Inferred)
• After siding: No Side Deck is registered, so there is no post-side plan; best-of-3 adaptation is unavailable as built (Verified)

Why it scores here

The deck opens reliably on its searcher engine: nine Elfnote/Power Patron core copies give about a 74% chance of at least one in a 5-card opening hand, and 17 searcher-text cards push that chance of a search effect near 95% (Inferred, hypergeometric). Its 10 hand traps plus 7 negation effects give it strong interaction on the second turn, where a 6-card hand has about an 85% chance of holding one. Its ceiling and median output are not measured: no recorded boards exist, so combo conversion rests on card text alone and is labelled Inferred. The score is held back by the absence of a Side Deck, the lack of any tournament or matchup evidence, and the mismatch between the Stardust Bystial label and an engine built from Elfnote and Power Patron cards (0% exact archetype purity). Popularity and archetype usage stats confirmed the list is real and accessible but earned no points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58, Going First ≈ 56, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 51. Modifiers: No Side Deck (-3); Engine conflict / archetype label mismatch (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated meta sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Searcher density (17 searcher-text cards) makes the engine reliably live on turns 1-2 (Inferred)
• Layered interaction: 10 hand traps and 7 negation effects cover both turns (Inferred)
• Compact 40-card main with 3-copy cores and a fully Synchro Extra Deck (Verified)
• Legal under MD rules with Limited and Semi-Limited restrictions respected (Verified)

Weaknesses

• No Side Deck, so no post-side adaptation (Verified)
• No recorded combos, so the ceiling and median output are unmeasured (Verified)
• Off-archetype engine mix: 0% exact archetype purity against a Stardust Bystial label (Verified)
• Hand-trap-heavy hands can brick on going first (Inferred)

Critical choke points

• The Elfnote/Power Patron searcher line: if the core is not drawn, the Synchro boss is not reached (Inferred)
• Single Synchro finisher routes: if the boss is removed or negated, the board stalls (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 40 main, 15 extra, 0 side; Maxx C at 1 copy (Limited) and Droll & Lock Bird at 2 copies (Semi-Limited) respect banlist limits; Copy histogram and Extra Deck composition (15 Synchro); Archetype purity 0% exact-name; usage stats show 4 core cards, all present; No tournament link and no combos or guides in the export
• Inferred: D1 starter probability from hypergeometric estimates; Hand-trap interaction density and going-second coverage; Ceiling and median output from card text only; Recovery and interruption resilience from searcher and recursion text
• Provisional: Meta Power and D13 matchup fit: no dated metagame sample
• 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/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null and the Stardust Bystial label does not match the engine's Elfnote/Power Patron core
