2 rulings from Wizards of the Coast
- 1 December 2004The 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.
- 8 June 2016Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keywords are activated abilities and will have colons in their reminder text.
