Why Aurelion Sol is favored
The low-elo edge fits Aurelion Sol's scaling win condition: keep the wave safe and build Stardust instead of giving Sylas repeated E2 all-ins. If Sol survives the early burst window, his abilities keep growing stronger, and Aurelion mains recommend hit-and-run W-Q trades after Rylai's while Sylas's E is down.
How to play as Aurelion Sol
Keep the wave near your tower and farm with attacks or Q instead of using Singularity(E) to shove while Sylas has Abduct(E); trade after his chain is spent.
After Rylai's Crystal Scepter, look for a short W-Q trade only when Sylas's E is down; Aurelion mains recommend hit-and-run trades once Rylai's is completed.
Aurelion Sol's damaging abilities generate Stardust that permanently improves all of his abilities, so his threat grows as he keeps farming and fighting over time.
How to play as Sylas
Hold Abduct(E)'s recast for Aurelion's Astral Flight(W); if Sol flies while your chain is ready, you can pull him in and interrupt the escape.
Abduct(E2)'s recast chain can interrupt Aurelion Sol's Astral Flight(W) when it lands, so Sol's flight is unsafe while Sylas can still recast E.
