Shaco is a assasin/jungler stylish kinda champ. If you use your Deceive right, you won't need flash, get another spell as, exhaughst or ignite. Shaco is very fun to play and when you're playing against a Shaco, have visionwards or a oracles, perfect for denying him!

A final tip when jungling...
Gank all the time :D

Start at wolwes, then blue, stael their red, recall. Get wraits, golems and look for ganks, if no gank possible take wraits, your own red, and at this point... YOU HAVE TO GANK. Then just go as you feel like beeing a good desition :) Good Luck

And as always, gank all the time :D
