Update #7, the final one! Yeah, challenge complete! ^-^ Elite Four and Champion battle recaps (tl;dr-type) inside the spoiler tags.
The final team! I'm very happy with this party. Got to win with some of my favorites, including four NFEs. Also, Shuckle is amazing!
I'll see if I have time to come back and do another challenge in the future, before the thread gets closed for the next iteration. ^-^
