the guide looks good,but Shaco isn't made for mid lane.

This guy should probably turn 'comment to vote' on...

Well, personally, I don't rate AP Shaco mid much because if you play a Vision Ward in the middle of the lane, all Shaco really has is just spamming E and if and only if the opponent has low enough hp, to gap close with Q and then tagging them with Ignite, which is never a solidly fantastic thing. His boxes are decent for farming and freezing the lane, but I just don't ever see Shaco doing well in mid-lane. Any typical mid-laner should really zone and outfarm Shaco by far. You already say this, yet then why would you pick Shaco mid...?

Your build leaves Shaco squishy pretty much all the way throughout the game. I don't like that one bit.

I'd rush a Chalice of Harmony into an Athene's Unholy Grail, though. Better for mana problems and great CDR to spam boxes and shivs.

The guide itself lacks coding.

Meh. I'd like to downvote, but I feel I'd be doing it simply because I don't like AP Shaco mid.

Where as the two other voters didn't comment on this, I think it should be a must, if you vote a guide down.
There are many things that I don't like/ would improve about this guide, but I will focus on the main ones:
1. Heal and exhaust might be vialable, but ignite is way better, because in combination with your traps and exhaust Ignite can - especially as Shaco AP - make a difference between killing sb or not. I would even take Flash over Heal.
2. Your chapters need to be updated. You have no pictures, no videos and no coding what so ever, which makes your guide really boring. One hint: Use Shaco to reveal Shaco. For further tips on how to make a guide, you should look up the information.
3. Shaco ap mid is fun to play, but not vialable in ranked games for example, especially not with your set up, so this is just a fun guide and no competitive guide.

Hope this helped you and I would be glad if you check out my Shaco guide for some inspiration. ;)
