Dwarven Reforger

{1}{r}, {t}, Sacrifice a nontoken artifact: Search your library for an artifact card with converted mana cost equal to 1 plus the sacrificed artifact's converted mana cost, put that card
onto the battlefield, then shuffle your library. Activate this ability only any time you could cast
a sorcery.
The art of true craftsmanship involves an incremental process of melting and reforging until all doubt is hammered out.
