5 rulings from Wizards of the Coast
- 15 September 2013Heroic abilities will trigger only once per spell, even if that spell targets the creature with the heroic ability multiple times.
- 15 September 2013Heroic abilities will resolve before the spell that caused them to trigger.
- 15 September 2013Heroic abilities won’t trigger when a copy of a spell is created on the stack or when a spell’s targets are changed to include a creature with a heroic ability.
- 1 February 2014If Mindreaver leaves the battlefield, and later another Mindreaver enters the battlefield, it is a new object (even if the two were represented by the same card). The last ability of the second Mindreaver doesn’t refer to any cards exiled with the first one.
- 1 February 2014The cards are exiled face up. All players can look at them.
