Hello, it's 2k elo player here. So basically it's very easy to carry with Shaco.
Here is my Shaco guide.

There is no much to say, just take what i have recommended.
You need that attack speed and armor pen isn't bad.
Basic jungler armor seals and mr/lvl glyphs.

No much to say. Just pick these masteries to RAPE your enemy.

Always start with boots. and 3 healing potionand rush for
Next you want rush the brutalizer if you get early kills.if you don't get early kills, just build
Next item:--->vs AP team orvs AD team OR JUST IGNORE TWO OF THESE AND GO.

If you built , upgrade it
Okay, lets end this ********. just go after ghost blade, then build and for last op item buy something offensive item or just go or

why not max E first, it scales the best and the slow is AWESOMEE
and box second, because maxing Q is waste of skillpoints.

With ignite, LIEKKI PALAA!it's super easy to get first blood and ofc take smite

Put 1st box (at 35sec) to protect you if enemy engages. 2nd at wraiths/wolves. 3rd at Red/blue. 4th Red/blue. Then do wraiths/wolves with you teammates help. Then put last box at Blue/Red and do it. Then go take another buff (Blue or red) and go gank OR invade enemy jungler.
