Open Challange

2 On 2
DQ: 5 Days.
Arena: Desert Oasis - A very hot area, sand in every direction with a few trees and a small lake in the middle of the Oasis, it's not very deep nor very shallow, wide enough to fit a Gyrados but not a Wailord. No rocks anywhere but the bottom of the lake. In case a Pokemon is underwater, it is still visible clearly.

Any takers?
