When Cloudreach War Falcon attacks, you may
exile up to one target Knight or Soldier you
control, it gains +X+X until end of turn equal
to the exiled creature's power and toughness.
Return that card to the battlefield under its
owner's control at the beginning of the next
endstep if Cloudreach War Falcon is on the
battlefield.
