2 rulings from Wizards of the Coast
- 1 October 2009If the enchanted creature becomes the target of a spell or ability, Ice Cage's ability triggers and is put on the stack on top of that spell or ability. Ice Cage's ability will resolve (causing Ice Cage to be destroyed) first.
- 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.
