Card-Specific Rulings
You can play the Fire spell even if you don't have a Fire hero. — Sirlin, 03/03/16
The Fire spell is played after you declare what you're attacking, but before that attack actually happens. If spell kills the thing you were attacking, you choose a new thing to attack, but this does not trigger the ability a second time that turn. — Sirlin, 03/03/16
