The only sigi variant I can think of that actually significantly threatens the team is offensive cm roost. Defensive variants are handled by rest regi (and also knock venu and aurorus and dug if it isn't cosmic power), and regular lo sigi can't 2hko togetic and has to play around numerous mons that can tank a hit to chip and then heal it off. CM Roost with Heat Wave could definitely be threatening though.
RU team tour, I'm gmt-5 (us central) but my work schedule is made weekly and I'm working this weekend. I usually work 7-3 my time so would prefer late afternoons/night but I'll be able to let you know if I get any off days hopefully by tomorrow.
ru summer seasonal, im gmt -5, showdown username enemyjurist, can play most of the time. You're -7, correct? let me know when you can play and on what server. assuming your showdown username is anja as well.
