There is a doubles trainer in Celadon(west, and cut the tree), the opponents Pokemon have the ability flash fire, so they always attack each other with fire moves which makes sketching a move much much easier.
A lot of questions about the prizes and we get this.. Love it.
LF tourney events with these prizes tho :)
