I sometimes use a team of:
I’m on PS4, so no Devoted for me, but mine works much the same way. Alastair tanks, buffs everyone’s armor and removes purple, Valk feeds the other three and loops, and Templar buffs armor and loops. There is a little bit of mana-blocking with Alastair taking red before Valk, and Templar turning reds to green, but as long as Alastair doesn’t get overwhelmed in the first couple turns and Rowanne doesn’t get BoneDragoned, then this team can sweep the board. Like Tacet’s team, it is a bit of high risk/reward, but fun to play.
