Horizon Scout

When Horizon Scout 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 Horizon Scout has a +1/+1 counter
on it, it has ward—{2} and cannot be blocked.
