General Grievous

Devour 2, Trample
Other Droids you control get +1/+1.
Whenever this or another droid you control dies, you may move its +1/+1 counters onto this card. If you dont, search your library for a droid card with CMC equal to or less than the power of the droid that died this turn. Put that card into your hand, then shuffle your library.
