I am having problems with Noel atm but that's mainly because I am doing a Dark type mono and non of my pokemon can really touch that Clefable.
Cinncino is also being a problem and usually puts a dent into my team from the get go with those constant flinches... Is it holding Kings Rock? It must be...
Edit: Just won against Noel with my Dark Mono team I didn't even train more like I should of my pokemon are lvl 50 - 52 I just managed to get lucky I guess? Not really I mean I didn't get a crit but he switched to clefable against houndoom some reason when I used nasty plot and I managed to take out that damn Clefable!
