There's always Miguel Sandoval, who can do Teleportation spell up to 18", and burn away with Gehenna Puker. The spell takes up 2 actions, so you'd probably want Miguel go last in the round, make some damage and hope for the initiative win next round.
I was thinking a scenario with him, where I'd teleportate Miguel behind an enemy squad, burning a couple, and with his 3 wounds survive the next round, where enemy squad remains would have to turn around and have only 2 ac left for shooting. Back up Miguel with a smoke cloud shot by another model, so he might actually pull this one off!
