Mold Hound

When Mold Hound enters the battlefield, you
may search your library for up to four land cards
and reveal them. Put one of them into your hand
and the rest into your graveyard, then shuffle
your library. You may then discard the land you
put into your hand.
Whenever you discard a land card, put a +1/+1 counter on Mold Hound.
It grows where others rot.
