This is giving me a headache, so I'm not going to get into much detail here. Simply put, that any of you are seriously talking about a ban for Purph speaks to me of the format being in almost TOO good of a place, such that the perpetual rules tinkerers have run out of widely compelling targets to pick at. If we're sincerely discussing banning a card this low in impact on the overall shape and attitude of the format, EDH is in a pretty good place and can probably just chill for now.
