Shaco can be built so many ways, I have about 170 games with Shaco so I believe I can speak for him fairly well. AP build isn't as good as AD, for the fact that AP denies half of your champion, your deceive, passive and clone's auto attack (as well as yourself) all revolve around AD. This build is pretty fun, and I recommend trying it out at least once. Shaco has 2 purposes in a game, killing carries during team fights, and backdooring. He's the best 1v1 champion, and the best champion to escape with, so why not abuse it? Hence, my build.

Cloth and 5 potions, good for all junglers, pretty simple. The reason I go vampiric scepter before the long sword to make the claws, is because you can jungle for a while easily with lifesteal ( you don't have to recall for health until you get the cash for wriggles). Boots of mobility is a must, you can back door, and escape, run into a team fight, gank, steal baron, all so easily when using these boots. Because of your decieve, you can leave a fight and get the 5 movement speed to run away without ever getting caught! Sheen is also a must for shaco, because doubling his damage, with decieve, his passive, oh my gawd. The damage makes you remember shaco pre nerf :) You should get kage's pick before sheen though for the extra gold. Trinity is obviously what to get after that, since you got sheen already. Extra slow, health, attack speed, and crits! Yum. Infinity edge is nice with the whole deceive sheen trick, making super big damage. I normally can hit 800 damage at the 35 minute mark with that combo, to be able to kill a carry with 5 auto attacks, much less if you use your spells too. Banshees allows you to not get stunned so you can escape, stun = gg for shaco. Deathfire grasp helps you kill carries much faster, since they won't have too much mr making that 30% a reality. And double bloodthirsters for the extra damage.

If you don't understand how to play him, which most don't, let me explain. As I said before, you backdoor and kill carries in team fights. That's all. If you backdoor, one person normally defends against you, which is what you want. 1v1 = win. In a team fight, go for the squishiest carry that's in the back. Make a clone and make it run in pretending it's you, they will use their stuns and what not on him, letting you deceive for the kill. In the beginning of the game, going double golems into lizard is the best way to go, doing this allows you to stay ahead of your solo lane's level. It is simply the fastest route. After wraiths you should hit lvl 3, where you go gank the middle lane. If they have flash, your main objective is to make him waste it to gank again later. If he doesn't, ghost deceive, hit him once, and then box in between him and his tower to make sure you get the fear. After you do this shenanigans, run to your golem, box behind him, have the aggression get on the box, and kill him. (Level 2 box allows the golem to force him to kill it with 3 attacks instead of 2). Get the wolves after, and you'll be level 4 with about 550 gold. Ward the map with boxes, and wards ( DO NOT STACK BOXES, THEY ARE USED FOR FEAR AND FEAR ONLY ), and take their buffs, dragon after wriggles, and keep map control. That's about it, thanks for reading.
