Hammerhand Tanker

As an additional cost to cast Hammerhand
Tanker, sacrifice a Mountain. When this
creature enters the battlefield, it gets -3/-0 if
you do not control an Equipment artifact.
{r}: Target Dwarf gets +1/+0 until end of turn. Activate this ability only once each turn.
These elite Yyanos warriors seem to actually enjoy
getting punched in the face.
