BurntSteel Gemfinder

When BurntSteel Gemfinder comes into play, Excavate. (Put a mine counter on target Mountain. It becomes a Mine in addition to its other types.)
{1}{r},{t}: Draw a card, then return BurntSteel Gemfinder to your hand. If you control three Mines or more, draw two cards instead.

A dwarf never returns home until he finds something interesting.
