Depala, Pilot Exemplar (178) [Kaladesh]

Other Dwarves you control get +1/+1. Each Vehicle you control gets +1/+1 as long as it's a creature. Whenever Depala becomes tapped, you may pay {X}. If you do, reveal the top X cards of your library, put all Dwarf and Vehicle cards from among them into your hand, then put the rest on the bottom of your library in a random order.
