My Black team consists of- (all between levels 50-65, I don't have much time to train normally ' )
My white team, that I worked a bit harder to customize, although they're still between levels 45-55.
Lucario M "Duncan"
Ampharos F "Arbiter"
Serperior M "Haku"
Samurott F "Lynna"
Zoroark F "Florence"
And that should be about it, although it changes. Haven't found my perfect group yet.
