I'm planning on EV-training a new team (or more) soon, hopefully I'd then be able to eventually defeat more people in wi-fi battles, the Battle Subway and the PWT.
Heck, if you ever battled a "Nate" or a "Rosa" (the names I chose) over the wi-fi, then you probably destroyed me at some point in a battle.
