Lothian Abductor

Flying
Whenever Lothian Abductor blocks a creature,
exile that creature. At the beginning of your
upkeep, put an altitude counter on each creature
card exiled by Lothian Abductor.
When Lothian Abductor leaves the battlefield,
return all cards exiled with it to the battlefield
under their owners' control. Those creatures get
-1/-1 until end of turn for each altitude counter
on them.
