Class idea:
Skeleton Joe (Ambush and Deception)

(He has a skin in the Halloween pack)
Primary Fire: Bone throw/club
He throws a bone...
It is also a melee attack...
Secondary Fire: Collapse
Skeleton Joe collapses himself. This crouches him and makes him immobile, even when fired upon.
Maybe also regenerate health or take reduced damage? This is actually an ambush tool...
Custom Item: Skeletal Remains (Either start out with a set amount or run on a cooldown bar)
He tosses a collapsed body looking just like his own gorgeous self out on the ground in front of him. Of course, it is completely harmless. It can be destroyed, though it takes a while. It can be used as cover in extenuating circumstances. Skeleton Joe also spawns one of these upon death.
The premise: using his custom item and his deaths, he leaves a bunch of his corpses on the battlefield so they are not exactly an uncommon sight. He then collapses to disguises himself as them to ambush and escape foes as needed.
Poblem: It would be preferable to not have the skeleton joe's name display on mouse over when he is collapsed.
