Hexproof
Whenever you surveil for the first time each turn,
put a praise counter on this card.
{2}{u}{b},{t}: Cast target card in a graveyard if it
has a converted mana cost of X or less, where X
is the number of praise counters on this card. If
you cast a card this way, exile it instead of putting
it anywhere else.
If this card would be destroyed, put it on top of
it's owners library instead.
