Empoleon Help?

[Marcusube]

You can go for the typical Stealth Rock/Defog set which looks a bit like this

Empoleon @ Leftovers
Ability: Torrent
Level: 50
EVs: 140 HP / 116 Def / 252 SpD
Sassy Nature
- Stealth Rock
- Defog
- Roar
- Scald

I run this set on my Mega Swampert singles team. Basically it is for setting up the rain and working as a tank against Pokemon in the UU tier by functioning offensively and supportively

Empoleon @ Leftovers
Ability: Torrent
Level: 50
EVs: 140 HP / 116 Def / 252 SpD
Quiet Nature
- Rain Dance
- Aqua Jet
- Scald
- Ice Beam

I run 140 HP because Leftovers will always recovery 11 HP, the 140 EVs allows you to get that HP recovery then distribute a little into defenses to take a few Physical hits like a Drain Punch from Toxicroak.
