My question has to do with how the effects of Church of Sigmar work with forced effects. I was playing the game with a buddy of mine today and ran into the problem of weather the church of sigmar has any effects on cards such as bules force effect.
Church of Sigmar's effect reads: Kingdom. Opponents cannot target your units with card effects uless they pay an additional 1 resource per effect.
BULE's card effect: Forced: At the beginning of your turn, corrupt one target unit.
But how dose that interact with BULE's card effect? I know forced card effects can't be canceled or anything but the rules do not state anything about applieing a cost.. Also if he could not target one of my cards would he have to corrupt one of his own? thank you for any help on the matter.
