Ward.
While this is engaged, it doesn't take ability damage and can't be destroyed by abilities.
QCan this follower, which "can't be destroyed by abilities," be buried by abilities such as Yuzuki, Righteous Demon's Fanfare ability?
AYes. Burying a card is different to destroying it.
QWhat is ability damage?
AAbility damage is all damage except for damage dealt by two followers in combat or by a follower attacking a leader. Damage from Strike abilities, although triggered by an attack, is considered ability damage.
