Official rulings
Four official rulings apply to Heartfire Hero, newest first.
- Use Heartfire Hero's power as it last existed on the battlefield to determine how much damage it deals due to its last ability.
- If a spell or ability you control has one or more of its targets changed to a creature you control with a valiant ability, that ability will trigger if that creature hasn't yet been the target of a spell or ability you control this turn.
- If you create a copy of a spell on the stack and target a creature you control with a valiant ability, that ability will trigger as long as the creature hasn't yet been the target of a spell or ability you control this turn.
- Valiant abilities will resolve before the spell or ability that caused them to trigger.
