Ouphe Vandals
Creature — Ouphe Rogue
, Sacrifice this creature: Counter target activated ability from an artifact source and destroy that artifact if it's on the battlefield. (Mana abilities can't be targeted.)
The ouphes finally managed to still the clockwork monstrosity by catching themselves in its cogs.

The ability targets an ability on the stack, not the artifact, so it can destroy an artifact with protection from green or one that can’t be targeted by spells and abilities.
