Deeproot Pathfinder

When Deeproot Pathfinder enters the battlefield, if you control another Merfolk,
Deeproot Pathfinder 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.)
"Stay here, cousin. I'll take a look."
