I just saw maharis' list and it looks both fun and powerful. However, I've seen some people question some of the card choices. I was wondering if anyone had any suggestions for trying to further optimize his list, if possible. For example, Navsi mentioned Fierce Empath as a strong GSZ target, which makes sense. What would come out, though? I also agree that there should be more removal, but what else can come out without hurting the combo synergy?
