I have a killer pet group that pretty much always wins in pvp pet battles:
- Jademist dancer
- Emperor crab (also works great with Toothy instead)
It's like every team I see runs a Valkyr or a deathadder team. It's just hilarious to beat these people EVERY time.
I got the 500 pvp pet battle wins under a week of battling.
You should really try it out!
