Passimian needs FFB and hex maniac in order to deal with volcanion. Babies one shot passimian which is really bad in the prize trade because you two shot volcanion ex. Additionally, mega ray shoul be a pretty good matchup as you have an easier time attacking turn one. 4 skyfield is necessary, too, as you have to have four passimian in play at all times while trying to bench shaymin, new, and oranguru.
Lurantis needs assault vest in order to deal with mega ray. It becomes much better after that as with max potion they are forced to lysandre in order to KO anything, really, while you can lysandre shaymins for an easy two prizes as well.
