Vestri, Western Dwarf

Other Dwarves you control get +1/+1.
Each Vehicle you control gets +1/+1 as long as
it's a creature.
Whenever Vestri, Western Dwarf 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.
