So to use a healing card, this must be played before a character is discarded?
An example is if I start a RA with Noah (8/7) and am blocked by Jezebel (6/6). Jezebel has intitive and plays Coliseum Lions "Discard one Hero in battle." If I have not interrupt/negate cards Noah is discarded and cannot play Balm of Gilead "Heal any Hero from the Blue Brigade that is being discarded."?
