I don't know if you still feel burnt out from the challenges, but if you don't, definitely go through the delta episode! You don't have any event challenges for that part, so you might want to get some more if you don't think it'll take the fun. All the money grinding seem like the worst part for you, so if you want to, you can also ask for new rule challenges following you through the delta episodes.
That being said, I think you should name rauquarza after lucariomaster2 because you forgot his event challenge c:
