Can anyone test something for me pls?

I want to pull for Mualani to use her with dehya, but i don't know if the team i came up with will have problems with Mualani not being able to vaporize. Can some test the team Mualani, Kachina, Dehya and Barbara pls?

My worry is that Kachina will consume the pyro aura instead of Mualani, and Dehya's slow application won't be able to keep up.
