You are about to confure us - again, the third time.
With all due respect, isn't it a bit preticipate to say, 4/252 Calm Blissey does not exist, when they are used in the on-site analysis? Granted, they outdated, but even according the actual stats this spread is used on one of five Blisseys.
So are we allowed ask again? What kind of advantages does 4/252/252 Calm has over the classic 252/252/4 Bold?
