Snover isn't really going to be around much longer after the Bulky Water dies. It's certainly not staying in on anything else.
Snover has *base 40* speed. I can see an argument to run EVs to catch Swampert, but you need 96 EVs just to catch -Speed Swampert and 164 EVs to outspeed Impish Swampert. Snover can't really afford to lose Special Attack or it's worthless on that front - you really need the 252 EVs in order to accomplish *anything*, and Snover becomes less able to take simple hits without HP investment.
