Tank Shaco?

Current shaco can be played AD, Crit, AP, Tank, And support.

Don't worry though, once his new rework hits he'll only be able to be played AP.

You can play almost any champ as Tanky DPS.

It is the items in most cases that need to really be fine tuned.

Titantic Hydra and Black cleaver are often the only damage items you need which also provide HP

Coupled with a Warmog's and Spirit Visage and Randuin's Omen just gives you ridiculous HP, Regen and snare/AS reduction/Dmg reduction

At this point either the ADC takes you down or no one does.

Oh and Shaco is pretty much doomed after his rework. The devs really don't know what they are doing and they are more satisfied with tweaking the his numbers and fooling the community that a nerf is actually a buff.

Also the Devs recently revealed that much of there research on Shaco's change came from video done by Pinkward. Thank him for the terrible Illuminati box ult that was suppose to resolve shaco's group fight issue but really really really missed the mark.
