Highland Pathfinder

Whenever Highland Pathfinder attacks, each other tapped creature you control 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 the creature, then put the card back or put it into your graveyard.)
Crew 3 (Tap any number of creatures you control with total power 3 or more: This vehicle becomes an artifact creature until end of turn.)
