Make sure it has flash fire because the field does fire damage to grounded pokemon and there are a lot of ability capsules in reborn so it shouldn't be an issue if you want intimidate or justified

Also not gonna lie agility may help but I'm not sure when you could use it

Thanks for the help! I set the field on fire with Arcanine and before that I managed to poison him with a poison jab, Toxicroak ftw! After that it was a sweep.
