Drillworks Mole
Artifact Creature — Mole
, 
: Put a +1/+1 counter on this creature and a +1/+1 counter on up to one target commander creature you control.
The Flaming Fist soldiers prepared to face a bulette, or worse, but the cause of the rumblings turned out to be much more benign and bizarre.

Rulings
If you target a commander creature with Drillworks Mole's activated ability and that creature is no longer a legal target as the ability resolves, you will not put a +1/+1 counter on Drillworks Mole. Conversely, if the target is still legal, you will put a counter on the commander creature you control, even if Drillworks Mole is no longer on the battlefield as the ability resolves.
