Ao, Benevolent Wanderer

Whenever a creature an opponent controls leaves
the battlefield but is not put into a graveyard,
you may draw a card and gain 2 life. If you don't,
put a land card from your hand into play.
{1}: Return target creature you own to your hand.
Any player may play this ability.
He comes to those who are lost, helps ones in dire need.
It is up to them to see beyond the monster.
