Arthur, Catastrophe Survivor

Changeling (This card is every creature type.)

Whenever two or more nonland permanents you
control are destroyed and/or exiled due to the same
source, you can return up to one target permanent
you control destroyed or exiled by that source to the
battlefield under its owner's control. If Arthur,
Catastrophe Survivor returns to the battlefield in
this way, put a +1/+1 counter on it for each other
permanent destroyed and/or exiled by that source.
