Another approach to defeating Fallen is consistency. In this style of play, you would fill your deck with Units that generate either one or two Blood, and avoid buying Scout or Elite, so that almost all your turns will fall within a narrow band of 5 or 6 Blood. After all, it does not good to get Kami if you generate a massive amount of Blood on a turn where Fallen is doing its Trick.
The problem with building a deck to enforce turns that are just OK, but never great, occurs if you are facing a high-powered Monster such as Demon. A deck which cannot beat all the Monsters in the current mission is a losing deck. It does no good to defeat Fallen only to paint yourself into a corner in which you can never win the game.
Which approach do you prefer? Or do you have a better one? Post your reply below!
