Identity & game plan
- Win condition: Bystial and Dragon boards: GY-banish Special Summons into 2500-ATK bodies (Lubellion, Druiswurm, Magnamhut, Saronir, Baldrake), backed by Fusion Dragons (Sheou, Lady's Dragonmaid, Filia Regis); Albaz Dragon Fusions (Lubellion the Searing Dragon, Mirrorjade) when Fallen of Albaz is live; Chaos Angel as Synchro finisher
- Turn 1 (going first): Open Chamber Dragonmaid or Magnarokket with a searcher (Dragonmaid Changeover / Bystial Magnamhut / Bystial Lubellion), then convert the GY banish into a Bystial or Dragon board
- Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Maxx C and Nibiru to answer the opponent's first summon or search, then rebuild with Lubellion or Red-Eyes Darkness Metal Dragon
- Recovery: Recur through Chamber Dragonmaid, Dragonmaid Changeover and Branded Regained from the GY; Mulcharmy draws when the board is empty
- After siding: Not applicable: the deck runs no side deck, and Master Duel is normally a single game
Why it scores here
The deck reliably opens a live starter only about a third of the time per 3-copy card in a 5-card opening hand (about 0.34), but the searcher density (about 0.82 for at least one searcher in hand) and six hand traps give it a usable first-turn and second-turn plan. Its ceiling comes from GY-banish Bystial and Dragon Fusion boards that reach 2500-3500 ATK bodies, but the median output is held back by roughly 18 archetype families sharing 40 slots, with 54 off-archetype copies and no combo boards recorded to confirm conversion. Recovery and resource economy are the deck's strongest traits, with several draw and GY-recursion cards. Popularity was not rewarded: the archetype label 'Stardust Bystial' matches none of its cards (no Stardust monsters, exact-name purity 0%), and the score is the structural read of the system, not an average of card scores. The absence of a side deck and of any tournament or meta data caps the score and keeps the Meta component provisional.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 58 | P(>=1 of a 3-copy starter in a 5-card opening hand) ≈ 0.34 for Chamber Dragonmaid, Magnarokket and Lubellion; searcher P(>=1) ≈ 0.82; starters split across 3+ routes (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 19 single copies across 3+ engine families (Dragonmaid, Rokket, Bystial) plus several cards dead without setup (Harpie's Feather Duster, Super Polymerization) mean conflicting or dead hands are common (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | No parsed boards, so the ceiling is text-only: Bystial GY-banish into 2500-ATK bodies and Fusion chains into Sheou or Lubellion; Albaz fusions gated by a single Fallen of Albaz (Inferred) |
| D4 | Combo Floor & Median Output | 45 | Median output cannot be measured (no boards recorded); the multi-engine structure suggests frequent single-line starts that stall (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 58 | Six hand traps (Ash Blossom x2, Droll & Lock Bird x2, Maxx C, Nibiru) plus recursion from Chamber Dragonmaid, Dragonmaid Changeover and Branded Regained give more than one live line after disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Draw sources: Pot of Sloth, Triple Tactics Talent, Mulcharmy Fuwalos and Purulia, Branded Regained, Maxx C; GY recovery via Changeover and Chamber Dragonmaid (Inferred) |
| D7 | End-Board & Interaction Quality | 55 | Interaction spread across hand traps, Harpie's Feather Duster, Dragonmaid Tidying, banish effects on Druiswurm, Magnamhut, Saronir and Baldrake, and Sheou's negate; no floodgates (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 60 | Going-second hand-trap density is decent (≈0.65 for at least one hand trap in a 6-card hand, Inferred); board-breaking is thin, with Duster and Super Polymerization each single or limited (Inferred) |
| D9 | Offensive Pressure & Closing Power | 65 | End-board bodies at 2500-3000 ATK, with 3500-ATK Sheou and Chaos Angel via Extra Deck; closing depends on one of several Fusion routes (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 40 main cards with 28 distinct names and 54 off-archetype copies; 19 single copies and several off-theme techs (Triple Tactics Talent, Chaos Space, Pot of Sloth) lower compactness (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 14 Extra slots with 9 Fusion, 2 Link, 2 Xyz, 1 Synchro; House Dragonmaid x2 and several Dragon Fusions give coverage, but Albaz-gated Fusions are dead without Fallen of Albaz (Inferred) |
| D12 | Side Deck Adaptability | 30 | No side deck (0 of 15 allowed) and Master Duel is normally a single game, so no post-side adaptation exists; scored low with low weight in the Midrange profile (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament_context or dated meta sample; archetype share unavailable, so D13 is a neutral placeholder and excluded from Structural (Provisional) |
| D14 | Pilotability & Error Tolerance | 50 | Several engines and Fusion, Link and Xyz decision points raise error load per turn; the line requires tracking which Dragons are live (Inferred) |
How the score was computed
Strategy profile: Midrange, meta-neutral (D13 dropped, weights renormalised over 95). Structural ≈ 54.6, Going First ≈ 50, Going Second ≈ 57, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: engine conflicts (-3); dependence on one card (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; D13 excluded from Structural)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.34 · 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
- Legal in Master Duel with every Limited and Semi-Limited card at legal copies
- Dense searcher and hand-trap package (11 searchers, 6 hand traps)
- Strong recursion and draw sources for a long game
- Extra Deck covers Fusion, Link, Xyz and Synchro with 2500-3500 ATK bodies
Weaknesses
- Archetype label 'Stardust Bystial' matches no card in the deck; the list is a Dragonmaid/Bystial/Rokket mix
- Multiple engines compete for the same hand and GY
- Albaz Dragon fusions depend on a single Fallen of Albaz
- No side deck
- Core archetype usage is thin: 4 of 25 standard core cards present (16%)
Critical choke points
- Fallen of Albaz (1 copy) gates Albaz Dragon Fusions
- Chamber Dragonmaid and Lubellion (3 copies each) carry the first-turn plan; each is about 0.34 to open
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Triple Tactics Talent and Chaos Space | A second engine piece in the Bystial or Dragonmaid core, or a second Fallen of Albaz | Cuts off-theme dead draws and strengthens the main engine's consistency |
| 2 | Super Polymerization | A Dragonmaid or Bystial searcher | Super Polymerization needs a discard and a Fusion target; a searcher improves hand access |
| 3 | Archetype label | Relabel as Bystial or Dragonmaid, or add the Stardust core cards if the label is meant | The label does not match the list, so archetype stats and guides attach to the wrong engine |
Evidence & confidence
- Verified: Legal main 40, extra 14, side 0 under Master Duel size rules; All Limited and Semi-Limited cards run at or below legal copies; Zero Stardust cards; exact-name purity 0%; Side deck is empty
- Inferred: Hypergeometric opening-hand odds for starters and searchers; Engine conflict and brick rate estimates; Ceiling and median read from card text only
- Provisional: Meta Power is null; D13 matchup and format fit is a neutral placeholder excluded from Structural
- 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 and going-second splits are inferred Meta Power is provisional without a dated metagame sample Archetype label 'Stardust Bystial' does not match the deck's cards; archetype usage stats may describe a different list
