Is damage assigned to a card but NOT applied to the card considered to be on it? E.g. I have Valkia in my quest zone. In combat, my opponent assigns 4 damage to her, enough to remove the card. Can I trigger her ability by paying 2 resources before damage is APPLIED to shunt the damage to target corrupted unit (Assuming one is available)?
Secondly, I didn't see any mention of maximum hand size, so I guess there isn't one?
