This is the first team I have posted, so any help would be welcomed. Also, I have been having trouble deciding who to choose as a fifth or sixth pokemon, so suggestions for that would be welcomed, and I have not gotten very far on making these pokemon perfect, so if a switch is needed, I'll listen.
