Since azumarill appears to be a problem for clawitzer, I think it is a good idea to run sludge bomb/sludge wave, as previously posted. one small note though, some azumarill are running 84 speed evs in order to outspeed min-speed jellicent. since clawitzer would not take a play rough too well from azumarill, it might be a good idea to invest a little in speed to outspeed and nail azumarill with a poison type attack. a modest nature clawitzer only needs 16 speed evs to outspeed adamant azumarill with 84 speed evs. I was thinking the ev spread for clawitzer could be 240 hp, 252 sp.atk, and 16 speed.
