Azelf@BrightPowder[Levitate]
Naive 6HP/100Atk./152Sp.Atk./252Spd.
~Nasty Plot
~Psychic
~Shadow Ball
~U-Turn
Great sweeper. After a Nasty Plot, Psychic and Shadow Ball are amazingly powerful. U-Turn is mostly a filler; I'm planning on replacing it with Explosion when I get Azelf to a high enough level.
Porygon-Z@Life Orb[Adaptability]
Modest 6HP/252Sp.Atk./252Spd.
~Nasty Plot
~Thunderbolt
~Ice Beam
~Hyper Beam
Amazing special sweeper. After a Nasty Plot, Hyper Beam has an effective base power of 780, which, combined with Porygon-Z's high Special Attack, makes able to OHKO just about anything except Ghost-types. It'll even OHKO standard Blissey!
Swampert@Leftovers[Torrent]
Impish 252HP/6Atk./252Def.
~Waterfall
~Earthquake
~Avalanche
~Protect
The only primarily physical Pokémon on my team. It works great as a tank, because it can survive a few hits from either end of the attack spectrum, although physical attacks do a bit less, and Protect every other turn to double the Leftovers recovery without getting hurt.
I still haven't lost with this team.
