Kelpwood Ranger

When Kelpwood Ranger enters the battlefield,
it 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 or put it into your graveyard.)
As long as the number of cards in your hand is
equal to or greater than your maximum hand
size, you may play an additional land on each
of your turns.
