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.
With this build i give you a way to try shaco, I can't say that this is the best way. But when I play Shaco i always use this build.
-Good in team fight
-High attack damage
-Beautiful withoth skins xD
-Hard to play well
Marks, Seals and Glyphs: I choosed AD cause Shacos must have AD to do anything withouth AD he will die. I might choose Critical Damage cause it makes your decieve skill much more stronger but i think auto atack damage is more important.
Quintessence: I choosed HP cause Shaco have very low hp and early game i think it can help you lot.
Some more description soon.
