As seen on stream when I do it live. Alternatively if you want something more stable you can take away a Wisp one each of stacks 1 and 3, add another Wisp to stack 2, and gives you enough DU's for Ensnare Auras on top of each SD Aura. 4p friendly from W29 onwards assuming you started at W28, I usually use 1 Wheeler, 1 Guardian Summoner for Stack 1, 1 Guardian Summoner for Stack 3, then a TB Monk somewhere in the middle just to keep Auras up with low maintainance.
