Hello there. Please take the time to fully evaluate my semi-competitive team. By semi-competitive I mean that only like 4 of my Pokemon are EV trained, and I will only occasionally use this team for battle.
@ Light Clay
Nature: Rash (+Sp.Atk -Sp.Def)
This is my set up Pokemon. Dual Screens to help the next Pokemon, and Taunt to stop other set ups and cripple sweepers. Serperior has the Speed to pull this off, but if it finds itself in trouble, it can use Giga Drain to heal up.
@ Choice Band
Nature: Careful (+Sp.Def -Sp.Atk)
@ Choice Scarf
Ability: Flash Fire
Nature: Lax (+Def -Sp.Def)
Note: I also have a Shellder and a Gallade, but they are works in progress.
