I see you cut to only 2 Rituals...with higher cost cards they become even more important. I think if there is a concession to playing further up the curve we also have to concede that mana acceleration is needed. Pox is mana-hungry as it is, even if you top out at 3, simply because we kill our own lands and Wasteland is really a spell.

On a positive note, I traded into a Liliana the Lost Hope this weekend, excited to see what it does for the deck. Still haven't gotten Karns, and at this point I might just wait out the Standard season until it rotates.
