Now that I think of it, I like the way how you can't reinforce units. This means when attacking there's actual strategy to avoid the big numbers, and for defenders you need to place your 8s in central key spots.
Soooo....how expensive was this house? $10? Maybe $5? Anyway, I doubt its worth more than 10 when it's in such close proximity to such a large swarm of *shivers* monsters.
@Gaarashatan123 Maybe not all of them, as the developers do still have to make money to keep updating it. I'm thinking a price of 30-50k on the oldest pack everytime a new pack comes out. That way, WB users get their benefit but normal users will also eventually get the cards as well.
