Ok, so how is Burying the Grudge for the Dwarves used?
"Action: Gain 1 resource for each unit that entered a discard pile this turn."
Makes no sense. If I use it on my opponents turn, then I lose those resources when my turn starts. But I can't use it during my turn, because the only real use would be during the battlefield phase and at that point it's too late to use the resources I have now aquired. So, what good is this card?
