Identity & game plan

Win condition: Synchro Summon 4000-ATK Dragons (Shooting Quasar Dragon, Red Supernova Dragon) or 3000+ ATK Stardust/Warrior bosses, protected by negations; Dragon Synchro recursion through Shining Star Dragon, Stardust Trail and Crimson Dragon searches
Turn 1 (going first): Open a starter (Stardust Trail, Shining Star Dragon, Ghost Belle) plus a Tuner, Synchro Summon a Dragon boss, and hold Infinite Impermanence or Forbidden Droplet for the first opposing play
Turn 2 (going second): Use the 6-card hand's hand traps (Droll & Lock Bird, Ghost Belle, Shining Star Dragon, Infinite Impermanence) to blank the opponent's first board, then Synchro Summon through the cleared field
Recovery: Recover the Synchro board from the GY through Shining Star Dragon, Stardust Trail's Special Summon and Ghost Belle's GY effects
After siding: Not applicable: Duel Links has no sideboard

Why it scores here

The deck reliably opens a starter in most hands: nine starter copies (Stardust Trail, Shining Star Dragon, Ghost Belle, Stardust Synchron) give roughly a 0.97 chance of at least one in a 5-card opening hand (Inferred, hypergeometric). Its 11 negation-text cards, including 8 hand traps, make it strong at protecting a board and at blanking the first opposing play, which is why interaction and going-second board-breaking score high. The 9-card Extra Deck offers several 3000+ ATK Synchro bosses, which earns the closing-power score. The weaker points are the hand-trap-heavy main deck, which can brick going first, and the single-copy Stardust Synchron as the only searcher. The score comes from consistency, interaction and boss coverage on the system as a whole; it does not come from Stardust being a popular archetype or from averaging the card scores. No combo boards, tournament results or sideboard data exist, so the floor, median and matchup dimensions are provisional.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	70	P(at least one of 9 starter copies in a 5-card opening hand) ≈ 0.97; starters are 3-copy Stardust Trail, 3-copy Shining Star Dragon, 2-copy Ghost Belle and 1-copy Stardust Synchron (Inferred)
D2	Opening-Hand Quality & Brick Management	55	8 hand traps plus Droll & Lock Bird make a going-first 5-card hand prone to dead cards; a going-second 6-card hand has a 0.976 chance of at least one hand trap (Inferred)
D3	Combo Conversion & Ceiling	62	Nine Synchro bosses with Crimson Dragon, Red Supernova and Stardust Trail give a high ceiling from text alone; no recorded boards exist (Inferred)
D4	Combo Floor & Median Output	50	No recorded combo boards, so the median output is unmeasured and set to neutral; it is not a measured value (Provisional)
D5	Interruption Resilience & Route Redundancy	68	Dragon revival through Shining Star Dragon, Stardust Trail's Special Summon and Stardust Dragon's end-phase revive give several independent continuation routes (Inferred)
D6	Resource Economy, Recovery & Grind	62	Ghost Belle and Stardust Synchron recur from the GY, and Synchro Rumble revives a Dragon Synchro; resource regeneration is good but unmeasured (Inferred)
D7	End-Board & Interaction Quality	80	Eleven negation-text cards, including Stardust Dragon, Stardust Warrior and Shooting Quasar Dragon effects, give broad and layered interaction (Inferred semantic read)
D8	Going-Second & Board-Breaking Power	72	Hand traps and Droll & Lock Bird give strong going-second disruption, and Stardust Warrior negates summons; no going-second split data exists (Inferred)
D9	Offensive Pressure & Closing Power	75	Shooting Quasar Dragon and Red Supernova Dragon are 4000 ATK, Ruddy Rose Dragon is 3200 ATK, and Stardust Warrior is 3000 ATK, all with ATK or multi-attack text (Verified stats, Inferred closing)
D10	Main Deck Efficiency & Flexibility	78	A 20-card main deck, the Duel Links minimum, with 3-copy starters and 11 tech cards keeps the engine compact (Verified composition, Inferred consistency)
D11	Extra Deck Efficiency & Coverage	72	All 9 Extra Deck slots are Synchro Monsters that cover several Levels and ATK tiers, with no dead Extra slots (Verified composition)
D12	Side Deck Adaptability	50	Duel Links has no sideboard, so this is a neutral placeholder with no post-side performance data (Provisional)
D13	Matchup Coverage & Format Fit	60	The archetype's meta-share is unavailable; the only format signal is an unverified guide claim that the deck is a meta force, which is speculation (Provisional)
D14	Pilotability & Error Tolerance	58	Six Synchro bosses plus several Tuners and hand-trap timing windows make the deck moderately demanding for a new pilot (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 65.7, Going First ≈ 64, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: engine compactness (2); hand-trap brick risk (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*65.7 + 0.20*60 + 0 = 64.6, rounded to 65

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.97 · 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 list with no violations; Crimson Dragon runs at its limit of 1
Dense interaction: 11 negation-text cards including 8 hand traps
Compact 20-card main deck with 3-copy starters for opening-hand reliability
Nine Synchro bosses with several 3000+ ATK options and multi-attack

Weaknesses

No combo boards, tournament link or win-rate data
Hand-trap-heavy main deck can produce dead cards going first
Only one searcher-text card (Stardust Synchron) and a single copy of Synchro Rumble and Converging Wishes give little redundancy
usage_statistics in_this_deck flags contradict the card list (see data gaps)

Critical choke points

Stardust Synchron (1 copy) is the only searcher-text card
The Tuner count of 6 depends on Shining Star Dragon and Ghost Belle, which need to be in hand at the right time

Recommended changes

Priority	Remove	Add	Reason
1	Synchro Rumble	A second copy of Stardust Synchron, if the card list allows it	Inferred: more searcher access reduces dependence on the single-copy Synchron; the swap needs checking against the Duel Links copy rules before it is applied
2	One Droll & Lock Bird	A non-hand-trap starter or a Tuner	Inferred: lowers the going-first brick rate from eight hand traps while keeping going-second disruption

Evidence & confidence

Verified: Legal 20 Main / 9 Extra list, with no violations; Crimson Dragon is Limited at 1 and runs 1 copy; Card stats, Levels and Extra Deck breakdown (9 Synchro); Archetype usage data is present for 16 rows (it conflicts with the card list, see data gaps)
Inferred: P(at least one starter in 5) ≈ 0.97; Interaction density from negation and removal text; Going-first brick risk from hand-trap count; Going-second hand-trap coverage 0.976
Provisional: Meta Power (null); Matchup and format fit; Side deck score (no sideboard in Duel Links); Median output
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 are absent No win-rate telemetry (going-first/second, matchup, brick/starter rates): these are Inferred or Unknown Meta Power is Provisional: no dated metagame sample usage_statistics in_this_deck flags are false for Crimson Dragon, Shooting Quasar Dragon, Stardust Dragon, Satellite Warrior, Red Supernova Dragon and Ruddy Rose Dragon, but all six are in the Extra Deck card list; the card list was treated as authoritative, and the usage-stat matching should be checked Deck title is null, so the deck name cannot be confirmed from the export
