Rush.
Select an enemy follower on the field and deal it damage equal to this follower's attack.
QI have Mars, Silent Flame General on my field. If I play this follower, can I first give it +1 attack with Mars's ability, then deal 3 damage to an enemy follower with its Fanfare ability?
AYes. When you put this follower onto your field, its Fanfare and Mars's ability both trigger and become pending, and you may resolve the pending abilities in any order.
