My lineup was as follows;
Samurott
Zoroark
Scrafty
Swoobat
Ferrothorn
I can honestly say nobody was a huge competitor, because I had very odd tactics in defeating a couple of them, and the others were easy pickings, honestly. I rickroll'd Caitlin with Zoroark at the front of my party with Scrafty at the back, then Nasty Plot'd while she constantly used Psychic. Every one of her Pokemon used Psychic once and then they died, or I killed them before they could get it out, like Gothitelle. Grimsley and Shauntal were wiped out by Scrafty and Bulk Up, while I used a knockout strategy for rhe last one (his name escapes me) in which I had one Pokemon hit him twice, getting him down to Sturdy twice, then had the next one take it out, repeat for the next Pokemon, until I was able to spam Revives and live.
