Ward.
Each follower with 1 attack on your field has Aura.
Choose one. (1) Select an enemy follower on the field and deal it 3 damage. (2) Search your deck for a Fable follower that costs 2 or less, summon it, then shuffle.
QIf I can't select an enemy follower on the field, can I still choose option 1 and have nothing happen?
ANo. If you can't select an enemy follower on the field, you must choose option 2.
QMy opponent has this follower and a Knight on the field. They attack with the Knight, and I destroy this follower with a Quick ability, such as Execution, causing the Knight to lose Aura. Can I then destroy the Knight with a card such as Angelic Snipe?
AYes, you can. Confirmation Timing occurs after a card with Quick is played, allowing another card with Quick to be played afterward.
