5 rulings from Wizards of the Coast
- 26 April 2014If an inspired ability triggers during your untap step, the ability will be put on the stack at the beginning of your upkeep. If the ability creates one or more token creatures, those creatures won't be able to attack that turn (unless they gain haste).
- 26 April 2014The player who controlled King Macar when its ability triggered will control the artifact token, not the player who controlled the creature that was exiled.
- 26 April 2014Inspired abilities don't trigger when the creature enters the battlefield.
- 26 April 2014If the inspired ability includes an optional cost, you decide whether to pay that cost as the ability resolves. You can do this even if the creature leaves the battlefield in response to the ability.
- 26 April 2014Inspired abilities trigger no matter how the creature becomes untapped: by the turn-based action at the beginning of the untap step or by a spell or ability.
