Hi im getting close to Roshi (30-50seals until him) and was looking for good lineup for him and earth main, so far the best one i found is

Earth main, Roshi, Yagura, Sailor Sakura, since i dont have sage naruto nor killer Bee 7swords. I have 50/80 sailor fragments, but need to wait until next event to got her finally and was thinking about getting classic Sakura to 4* and buffing her skills until i got Sailor, since she is quite similar (same chase, dodge instead of getting tanky), with Yagura +20 chakra her mystery round 2 would be "free". Did anyone used her at 80+ lvl?
