Crossroads Demon

At the beginning of your upkeep, choose target
creature. That creature gets +2/+2 and its
controller's choice of Flying, Trample,
Vigilance, Lifelink, or Haste. Destroy that
creature at the beginning of its controller's
next endstep.

So my old evil spirit can get a Greyhound bus
and ride"
