Motive for Exploration

Delve (Each card you exile from your graveyard
while casting this spell pays for {1}.)
Whenever a card leaves your graveyard, target creature explores. (Reveal the top card of your
library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then
put the card back on top or into your graveyard.)
