Just in case you haven't seen this site, I highly recommend you check it out.

It allows you to pick various attack and defense cards and run battle simulations to predict win/loss percentages. It also shows you the total boosts/degrades for various cards.
For anyone working on their decks, or wanting to see how they hold up against a Captain America defense wall, it's a great tool. I've seen a few others like this, but this one is much easier to use and much easier to read.
