On Evolve - The next time this follower would take damage this turn, it doesn't.
QCan this follower's attack and/or defense be reduced while its On Evolve ability is in effect, such as by Nice Nature's Fanfare ability?
AYes, as that is not considered as taking damage.
QIf a follower with 0 or less attack, such as Bellringer Angel, attacks this follower, does it use up the effect of this follower's On Evolve ability?
ANo. Followers with 0 or less attack don't deal attack damage, so the effect remains on this follower after the attack.
