PVP Pet Battles

Just started doing PVP pet battles about a month ago, was just wondering if there are any unwritten rules regarding it, or poor etiquette, or is it basically anything goes.

There’s no mandatory etiquette as you don’t know who you’re battling and no way to report someone. The majority of PvP participants are good people but you will come across some real jerks. Kind of up to you which category to be in.

Sorry, I actually meant when it comes to building teams.
