One ruling from Wizards of the Coast
- 10 June 2022If 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.
