What should I upgrade next.

[Atturmpt]

Not sure what would be the most optimal order to upgrade. I'm going to stay around 1300-1500 trophies. I've got max mortors and wizard towers. My air defense are lvl 5, cannons lvl 9, archers lvl 8, and teslas lvl 3.

Your splash defence is maxed which is good but I would keep working on your Teslas, Archer Towers and Cannons and keep your walls going!
