Zilean tips
Just picked up 
recently, and man, is he much more fun than I thought he was originally. Anyway, I'm looking for a bit of advice when playing as him. I get that he's a late-game champ, ult the carry, and all that other stuff, I'm just wondering if you all have any tips on how to play him to his full potential.
On an unrelated note, what do you think is his best skin? Time Machine looks the best in my opinion, but Groovy is pretty darn good too.
