From the new rules:
"To be able to resolve an effect, it must have a valid target."
What does this mean?!?!?!?!
Does it when someone uses the Enhance on Amy's Ass on their own attack, if their opponent no longer has an asset to commit by the time you get to the resolution of the enhance they have to give their own attack a damage debuff?
Does it mean you can't use Bereaved (E: Your attack gets +1 damage. Gain 1 vitality) on your opponent's attack to just gain vitality?
