I guess you don't mean Pokemon Insurgence in that case, considering it has easy ways to grind out a perfect party. I don't mind making a competitive party... the problem is games like Reborn don't let you get hidden abilities or perfect movesets. In insurgence, before gym 1 you can catch a Delta Pokemon (type change) that can help you get through Gym 1's sun team. After that you have access to breeding, all important breeding items, a mini game that makes money fast, and a secret base that lets you have ev trainers, level trainers, items, healing, and access to wild mon with hidden abilities all in one place. So before gym 2 you can immediately start crafting competitive ready mons and do it very easily, and once you finish there's no need to grind ever again. IV's aren't important.
