Espeon65, take Ninja the Piplup. Ninja must learn Stealth Rock, and set it up at the beginning of every battle ninja is in. Ninja may only evolve immediately after soloing a major battle. If Ninja's level is not prime, it may only use NVE attacks and Stealth Rock And Pound. Ninja must be neither the lowest not the highest level on the team, yet the total BP of his moves must exceed the other teammates always.
