Shaco is by far my favorite mid laner atm. His burst damage is laughably stupid, and the enemy team will surrender by the time you are 1 shotting them wil no effort.

All I have to say is that DFG is the most op item in the game when used on shaco. Makes sure you pop DFG then e them, and if you are fed and there back is turned, it will 1 shot them. Lich bane is great for using your q, since you will get a ton of damage off with your crit. Shacos burst damage is vast in the late game.

Shacos e does 100% of your ap, that plus deathfire grasp will put them at help hp no matter what. His w scales very well with ap, and will basically be another champion with how much damage it deals with 800 ap. Even when building ap, if you have a lich bane shacos q will still do hilarious damage. You can figure out his ult on your own.

Cons:
Useless unless building glass cannon
Squishy
Not very good in a team-fight.

Pros:
Has the highest burst I have ever seen
Great trading with your e and w in early game
Easy escape

Try to get your team to lead the enemy into a bush with your boxes stacked into it, the boxes will do damage unlike no other. Your ult is great for baiting the enemy team if played right. even if they kill your clone, the damage it puts off will give you an advantage in a fight.
