That champion roster is one of the strangest I've ever seen in Raid. Scyl (day 180 log-in reward) and Arbiter, but only 9 champs at lvl 60. Did you pull both of them from shards?
Anyway, don't bother about tag team right now, you have to bring a bunch of champs to lvl 60 before you can build 3 competitive teams here.
Team 1: Arbiter, Apothecary, Spider, Trunda
Team 2: Skullcrown, High Khatun, Deacon Armstrong, Ninja
Team 3 is a bit harder to built. There is a lack of really good speedboosters on the one hand, on the other hand, you don't have the classical go 2nd champns like Duchess, Seeker and Rhazin. Maybe the following go 2nd team could do some work: Vogoth, Brakus, Souldrinker, Scyl.
