I was able to beat Code of Morality (10 power moves). Used Eternity / Hollowed cheese tactic to clear the first wave. After that it was relatively smooth sailing with Horus (Energy / Power) and Warrior Bomber Boy (Paralysis / Nightmare).
Try that setupThe stuns and sleep buys you time to get the 10 power moves. Once you get 10, you can go back to using Eternity/Hollowed tactic.
