Here's an OU team with a heat guzzlord set with roseli berry + belch; it takes a fairy attack from tapus and clef (except specs lele) and hits them with the belch. Toxapex is pretty annoying so psychium z on greninja might work better and replace mimikyu's z with life orb. I'm not the best teambuilder but I thought you might enjoy this :]
