in a hardcore nuzlocke the e4 also has an level cap but is it the final e4's ace or the champion's ace?
The player may not level any of their Pokémon past the level of the next “boss trainer’s” highest leveled Pokémon. “Boss trainers” can include Gym Leaders, Kahunas, team admins/leaders, and, when entering the Pokémon League, the final Elite Four member. Any Pokémon who exceed the level cap must be boxed, and cannot be used until they are under the level cap. Exceeding the level cap during the battle is allowed, you must simply enter the battle with no Pokémon over the level cap.
