Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
-Harass only when the time is right.
-Be crafty with your box's and use them for sight in dangerous areas.
-Watch your friends back by being the distraction but don't die. That's why your Shaco.
I don't feel as though much should be explained in detail. You will figure out how to play Shaco eventually.
The items i selected are a big hint as to one way you could play with him. But when i was a noob I remember early game being harder so I will explain that. Boots first just because that speed boost is either a possible kill or that slight speed boost to get away. I got two potions in my inventory to use over time. both should be done by like lvl 5-6. Use the mana potion whenever you feel like its the right time to kill someone to get that little money boost to be able to get "Mercury's Treads" so you can survive more from stupid stuns like those from Ryze or something, Slows like from Ashe's auto attacks, etc.
Deceive past trees towards where you hopefully hid a Jack in the Box to ensure your safety.
Usually by the time you hit Infinity's Edge and building the second Phantom Dagger the game ends.
Most importantly think outside the Jack in the Box.
So ya. Just remember every time you rage from dying, its usually your own damn fault for not doing something better that could of saved yours and Shaco's life.
They really make you give a 300 character description so i am going to just tell you about a funny LoL story. I once fought Ashe (attack speed noob), Warrick ( Life stealing noob), Garen (hp nooooob), Master Yi (the gay), and Sona (the heal's) and was able to outwit and solo them. execpt master yi x\
