Select any number of enemy followers on the field and deal 4 damage divided between them. If there are at least 10 cards in opponents' cemeteries, deal 8 damage divided between them instead. If there are at least 20, deal 8 damage to each enemy leader.
QWhen playing this spell, if there are 9 or less cards in opponents' cemeteries, can I select 5 enemy followers on the field?
ANo. You must allocate at least 1 damage to each follower you select for the target selection to be valid.
QIf there are no enemy followers on the field, but there are at least 20 cards in opponents' cemeteries, can I sill play this spell to deal 8 damage to each enemy leader?
AYes. "Select any number" means you can select 0 followers when playing this spell.
