A few turns in I managed to draw some lucky cards and emboldened Tempest who had his armor card and elemental thingy out. I was now able to heal all heroes for 4 HP a turn which went up to 6 when I drew the environment card that increases all damage and healing by 1. The good Baron never scratched my heroes - in the end, I won with everyone at full HP.
This stands out, are you sure you were doing it correctly?
You can only use each power once per turn. It is possible to have out 2 copies of Cleansing Downpour it is a rare occurrence.
3 heroes is considered by most the most challenging way to play the game, (H) scales in your favour but having only 3 turns between each villain/environment card makes for a lot of pain.
