Hi guys!
This is my first Mobafire build and i picked Shaco The Demon Jester as my first build/guide.
I've played shaco in many styles but i first tried to play AP, that went good until they nerfed his Jack in The Box.
After that i tried to play him as Attack Damage once and it worked very well. Quadra kill first try.
But i'll hope that you will like my guide and rate :)

Enjoy!

First of all i'll explain why i chose these runes.
For Marks i took Greater Mark of Furorfor some crit damage for my decieve and if i have al least 20% more critical damage in the beggining i can hit at least 210.
And if i play in lane against Ashe or Twisted Fate i can almost take them out with two decieves in the beggining, but of course i hit them with some basic attacks too.
Then for Seals i took Greater Seal of Fortitude for flat health that will make me unsquichy and i wont be so easy to kill in the beggining.
Then it will even help me later game but not so very much. But if i have early dominance in lane i will get feeded and later game i can just farm kills.
For Glyphs i took Greater Glyph of Alacrity for some attack speed. Its not so much attack speed but it can help me to last hit minions more effective.
And with more attack speed i can lifesteal my hp up faster.
And last but not least, for Quintessences i took Greater Quintessence of Furor for the same reason as i took the marks.
This will give you early game and late game dominance.

For Masteries i took a simple 21-0-9 with focus on lifesteal, crit damage and armour penetration.
There is almost nothing more to say about that, only that i can have 10% extra crit damage for my decieve. The lifesteal for low hp and armour penetration for extra damage overall.

Pros
/Shaco have a very good escapeabillity with both JiTB and Decieve.
/Very good early dominance with minion farming.
/High burst damage with a "Death Bush"(you place 4-5 JiTB in a bush and they walk into it)
/Can play both AD,AP and jungler.
Cons
/Very squichy.
/Hard to kill people late game.
/If people have oracles AD Shaco is useless.
/Hard to jungle with.
/Very expensive items in build.
