Bone Drawer was added in Beta 54.0.
Bone Drawer is quite unique, as its effect depends on if it actually dies or not, and not even going into your dustpile itself at any time.
When it doesn't die, it will turn itself into a Pile of Bones, effectively giving it +2/+1 and Armor. This is solely for a combo with Abstract Art. When it does, a quite powerful monster is added to your dustpile, making Bone Drawer (and by extension, Abstract Art) decent additions to a resurrection deck.
