I agree with devan about losing the quantum towers. Another thing, it has more cats than it has attackers. If you had them all out, the cost would be 10 entropy per turn. You can barely afford that. Just a little thing, but I would put the cap on 4 of them. I don't know the soul catcher very well yet. If you dont need the quanta, yes, take them out. I don't think 3 bonewalls are that bad for a 35 card deck. If you remove those 3 or 4 cards and add a few damage dealers to finish off, you might feel better. Poison is cheap and annoying, or maybe a dragon or 2 for the finishing blow. Without backup you only have the death effects, and it is always nice to have some other plan.
You will just have to test it a bit. If the skeletons alone will do it, fair enough. Don't make it bigger than needed.
