I had a question about a card
Cassial, The Selfless (formally Cassial, Champion of the Cause)
1 Purity Overseers, Cost 5, Morale 10, Unique Character, Angel, 7/7
Ability: If another Character you control would take damage while Cassial is not Ascended, that damage is redirected to Cassial and she Ascends, gaining flying.
When exactly does the ascending occur? Is it after the first attack, or at the end of the turn? For example, if it is the attack phase and my angels attacked into a defender, would Cassial take all that damage, and THEN ascend, or would she take the first hit, ascend immediately, and leave the remaining angels to take the damage themselves?
Could this be clarified in the card perhaps?
