C. They're consumed randomly. Perhaps I should clarify in the original post.
Most people would just assume it, I just wanted to make sure, so its probably not necessary, but it also would hurt i suppose either.
So my thoughts on the card. I love the effect, very original, very fun, and I would say 9/10
However, I wouldnt like it if this card got into the actual game, just because it completely reworks the whole concept of the game. But, I vote that this is a good card anyways, because the cards we make probably arent going to be in the game anyways.
