Hi, I've recently started playing Reborn Hardcore, and have just finished defeating Corey. I'm sorry if this question has been answered but during my first battle with him (which did not go well) he had different pokemon to the second time I battled him (after some level grinding). In the first battle he started with a Qwilfish and had a Swallot, Scolipede and a Nidoqueen. In the second battle he did not have those four, and instead had Nidorina, Skrelp, Croagunk and Grimer. His pokemon were also 4-6 levels lower than what it was previously. Was there a reason for this?
