First, I would consider giving Dugtrio Stone Edge or Memento over Sucker Punch. There are many instances where you will be using Sucker Punch and your opponent will just go for recover or something and you really need the guaranteed damage.
I would also give Politoed at LEAST 24 speed EVs to outspeed minimum speed Skarmory as well as Jellicent with significant speed EVs and toxic it before it can taunt you. You can put 60 speed to outspeed Heatran if you feel like you need to outspeed that, even though you have multiple answers to it on your team.
