Oh shit looney you're the mvp. 

I'm thinking Cerise's endgame team is gothitelle, sceptile, vespiquen, florges, quagsire, plus something huge and obnoxious and destructive. If I go the legendary route, probably giratina. 

Last thing, I failed to finish my post before work, so now I'm on my phone :'D I may or may not be able to get a post up soon.
