I'm really not happy with Eelektross. It's not particularly strong at anything and is actually easily knocked out. I also feel like she doesn't work well with my team. My Pokemon overall aren't very fast, and Eelektross just can't get the hits in quickly enough. I really need to have an Electric type on my team because my team needs a good counter to Water-types, and I feel like I might want to switch her out for something that hits faster and harder, namely Zebstrika.

I only play with Gen V Pokemon, so I'm not considering any Gen I-IV Pokemon at the moment. Also, sorry Galvantula fans, but I already have a Bug-type on my team, and I want to keep it diverse.

Here's the Zebstrika I would switch in:

Zebstrika - Mars - Female
Naughty Nature
Ability: Motor Drive
@ ?
Overheat
Wild Charge
Return
?

Obviously, the moveset needs help, and I don't know what item she would hold either.

I'm also considering Sawsbuck with the following set
Ability: Herbivore
Item: Big Root?
-Horn Leech
-Wild Charge/Swords Dance
-Return
-Jump Kick

So please let me know which Pokemon I should use and what you think would be good item/moveset options for whichever Pokemon you think I should use between Eelektross, Zebstrika, and Sawsbuck. Also, if there's another Grass-type you think I should really consider, or you please post it here with a suggested moveset.
