On Evolve - Select an enemy leader. Deal it 1 damage and give your leader +1 or
+2.
At the start of your end phase, each player chooses one. If their leader's defense is an odd number, they must choose (1). If even, they must choose (2). (1) They bury a follower. They give their leader -1. (2) They give their leader
+1. They draw a card.
QIf I only have a Heavenly Aegis, which has Aura and "this follower can't be destroyed by abilities" on my field, can this follower's ability cause me to bury it?
AYes. Aura prevents the card from being selected by enemy abilities, but in this case, you are the one selecting Heavenly Aegis. Also, burying a card isn't the same as destroying it.
QIf my leader's defense is an odd number at the start of my end phase, and I have no followers on my field, do I still choose (1) and give my leader -1 defense?
AYes, you do.
