I've seen a good lineup with midnight blade, mabui, darui and tenten gnw...

main mabui x
tentengnw darui x
x x x

talents are 2,1,1,1,2
They use the rhino summon which you could replace with the bull and then switch skills to 2,1,2,1,2

Hope this helps but it's mostly up to you to test and adjust the team according to how you think works best :)
