Wulfhardt High-Hammer

Other Dwarfs you control get +1/+0 for each basic Mountain you control.
Whenever you play a basic Mountain, create a 1/2 red Dwarf creature token.
Whenever one or more Dwarfs you control deals combat damage to a player or planeswalker, search your library for a basic Mountain card, put it onto the battlefield tapped, then shuffle your library.
