Stardust / Synchron Deck #765158 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 67/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: duel-links

Legality

Main 20 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro boss pressure (Red Supernova Dragon, Shooting Quasar Dragon, Stardust Dragon) built from Stardust Trail and Tuner bridges, with a single Limited Crimson Dragon as top-end; Board-control Synchro bosses (Stardust Warrior, Satellite Warrior) that destroy or negate opposing cards and trade down the opponent's field
• Turn 1 (going first): Open Stardust Trail or Shining Star Dragon to start a Synchro summon on turn 1 and hold Infinite Impermanence or Droll and Lock Bird for the first answer; the hand traps are often dead when going first
• Turn 2 (going second): Use Ghost Belle, Droll and Lock Bird, Infinite Impermanence and Shining Star Dragon as hand interaction during the opponent's turn, then convert with Stardust Trail or Stardust Synchron into a Synchro boss
• Recovery: Synchro Rumble returns a Tuner or Level 7-8 Dragon Synchro from the GY; Stardust Trail and Stardust Synchron recur from hand and GY when a monster is Tributed
• After siding: Not applicable: Duel Links has no side deck (side_count 0), so adaptation is only through in-game choices between hand trap and engine

Why it scores here

Stardust/Synchron scores in the Midrange band because its 20-card Main Deck is compact and built around 12 monsters, with three-of Stardust Trail and Shining Star Dragon as starters and three-of hand interaction (Infinite Impermanence, Forbidden Droplet, Droll and Lock Bird) plus two Ghost Belle. Its consistency comes from the system: about a 0.87 chance of a Stardust Trail or Shining Star in the opening five, but the summon needs a live tribute or a Dragon Synchro in the GY, so the score is not a card average. Interaction is the strongest part, with a going-second hand trap probability of about 0.98 and an Extra Deck of negate and destroy bosses. The closing power comes from 4000-ATK Synchro bosses, but the floor is held down by hand-trap-first openers and the absence of any recorded combo boards, so median and ceiling remain Inferred. Popularity and the guide's meta claims earned no points, meta power stays provisional, and the side-deck and matchup dimensions are neutral because Duel Links has no side deck and no dated meta sample exists.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 67, Going First ≈ 60, Going Second ≈ 74, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: engine compactness (2); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (no dated meta, Meta provisional): 0.80*67.0 + 0.20*60 + 1 = 66.6, rounded to 67

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · key two-card combo ≈ 0.33 · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Compact 20-card Main Deck with a three-of starter and interaction core
• Eight hand traps and a negate-heavy Extra Deck give strong going-second interaction
• Multiple 4000-ATK Synchro closers with several independent summon routes

Weaknesses

• No recorded combo boards, so the floor and median are unmeasured
• Hand traps are dead on some going-first openers
• Converging Wishes requires five distinct-name Dragon Synchros in the GY and is often a brick early

Critical choke points

• Stardust Trail and Shining Star Dragon both need a live monster or Dragon Synchro in the GY; without one the engine stalls
• Crimson Dragon is the only Limited card and a single copy; a restriction removes one boss
