I've been putting the Torterra raid off for a while but Serperior worked a treat. followed some YouTube strategy that had a weird EV spread (max def, 20 speed, the rest on spatk) but didn't feel much like training (also I thought it was supposed to be max spatk) so I just force fed my mighty Serperior 22 of the spatk vitamin and 4 speed vitamins (I can never remember their names). gave it a shell bell, then 2x breaking swipe, giga drain, taunt, terastalize, leaf storm and giga drain until it fainted. I fainted once near the end, after taking down Torterra's shield, but it ended up fine. the only downside is that Serperior can't relearn Iron Tail and I like to keep my mighty starters with their original set, but oh well.
glad these are over. now I'm gonna sit here and wait to see if they bring the mighty raids I missed back. I think it's just Empoleon, Blastoise and Greninja but I might be mistaken. I know we have the Rayquaza raid next month but since it's just a 5 star one I'm not that worried.
