Way back, I had CB+Top in the Knight build if you recall. It just wasn't good enough. Games end with your opponents playing a lot less cards out than before thanks to repeated Wastelands.
Whut?!!!
You are really funny, since "way back" was yesterday. On page 89, someone else suggests that you skip the CB/top for spell snares, and you go "splendid, i'll try that mate".
How much time have you really had to tests all these lists thrown around?
