This is my guide for Shaco. I havent used him long nd i'm not too good at writing guides but ive been doing well with him so please read and try it out.Thanks.

I go for completely Critical Strike runes because the amount of damage you can do with crits early and late game is ridiculous.

I use 21/0/9 because you need the extr damage and defence is useless.

I start with a Dorans blade as I find it helpfull. Then I get beserkers greaves for movement and AS. Then i get zeal for some AS. Then i get black cleaver for damage and the passive. Then I get Frozen mallet because you need health and the slow is really handy when they run. Then i get phantom dancer followed by Infinity edge for the crit chance and damage. Then i will probably get a warmthogs or thornmail.

Ghost and exhaust are just handy, but you can also use teleport instread of ghost
