Bog Beast

When Bog Beast enters the battlefield, it
explores, then it explores again. (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 or put it into your
graveyard. Then repeat this process.)
When Bog Beast dies, create X 1/1 green
Saproling creature tokens, where X is the
number of +1/+1 counters on Bog Beast.
