Kathryn if by chance you wake early, use Psychic on Reginald and then Shadow Ball on Hazel. No matter what use Heal Pulse on Flint on the third action.
Psychic (Reginald if awake) > Shadow Ball (Hazel if awake) > Heal Pulse (Flint)
Flint, you will move before Hazel can get out the disable, so start off by using Take Down on Reginald so that is disabled instead of Rockslide. Speaking of, follow with Rock Slide and then bring the pain with Head Smash on Hazel.
Take Down (Reginald) > Rock Slide > Head Smash (Hazel)
