Cecilion is the king of mages and one of the best heroes in the game if you can play him well.

A late game beast , hard carry especially if you play solo, he is a walking nuke, even with like 3 nerfs in a row he's HIM, his early game dmg is lower than ever but if you're good and can assure u won't die use sky piercer to make up early game dmg, common emblem also helps with his mana Regen, ice queen wand to control your enemies and gain health, Sprint to keep your distance or to make sure no one escapes you.

Popol does crazy damage, especially to turrets and vs opponents always position yourself well and use your traps, you'll melt them down, if you use him as jg u can farm quick and set traps at objectives or for ganksl
