One of the fun modes of online Pokémon battles will begin July 11 and here’s what you need to know. The Eevee Friendly will be a Rotation Battle with only Eevee and its Eeveelutions allowed to enter. Only those caught or bred in Pokémon X and Y are eligible to compete. So, none from Black and White or Pokémon Bank are able to battle.

Players may register from 2 p.m. on July 3 to 8:59 a.m. July 11 with the actual competition taking place at 9 a.m. all Japan Standard Time with the competition ending July 14 at 8:59 a.m. Participants will receive 1,000 Poké Miles but must record a win, loss or tie in order to get them.

All Pokémon are set to level 30, they must be in your Battle Box and you’ll be able to use four to six of them. This will be interesting since there are nine eligible combatants. And once they’re in the Battle Box, they stay there until the contest is over, so no moving teams around.
