SLURPUFF HELP

[iDrEaMiNbLuEsKiEs]

I want to have a Slurpuff on my team because they can be good tanks. Justin faced a really good one a while back and I thought it looked like a good Pokémon. (I haven't played X or Y) What are the best EVs on a Slurpuff, and what are some good moves for it? Also, what Pokés would complement a Slurpuff in a double battle? I also need a little help building a team. What are some really good X Y Pokémon that I could use? If anyone was shiny hatching Swirlix or Froakie I would love to get one when ORAS does come out and I get a copy. Thanks in advance! :P
