New World Explorer

Vigilence, trample
When New World Explorer 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.)
Whenever a creature you control explores, put a
+1/+1 counter on New World Explorer.
