Hey, found your build from a post on ippytrax'es guide. He is a all pro shaco player and probly very bussy making more awsome guides for all of us. Ill give my personal meaning if you want.

1. yellow attack damage runes are not optimal. This is a good guide to read. http://www.mobafire.com/league-of-legends/build/rune-tips-what-secondary-and-primary-means-and-more-24255
2. Archmage's savvy is not a mastery point you would want to have in a crit build, you should consider changing it for deadliness.
3. Skill order is abit wired, would like to hear why you do this please :D
4. Maybe write some thing in your guide to. some easy things, why those items, some tricks and things you would like people to know.
5. As a fellow shaco player i know for a fact, shaco has a big mana problem in lane. Your build dose not fix that problem. What i would do to fix the problem, get mana regain yellow and maybe even blue mana regain to.
6. heal and exhaust are ok but you need some thing that can save your life and supliment your spells. ghost is very very good at that. my personal preference would be ghost and exhaust.
7. Shaco needs a good early game. the items you have lined up are sow sow hard to get if you dont have a great game. Try and senter your build around early game. thats were shaco needs help.

Iam sorry if you found this offensive in any way. It was not ment as a insult more of a helping hand. If you make some changes to your guide, put in some more info, ill defently support this.

And Favorite it Like it Dislike it tell me what you think.

Comment If you like me to change something in the build .
