20 is wayyy to much healing for having 3 pillars.. i put that in my deck with 12 pillars in it and i gain 20 life 4 times.. 80 life total... wayyy wayyy toomuch. drop it to 5 HP or 10 HP. then 12 pillars would only be 5 X 4 = 20 or 10 X = 40 HP a turn max. this would overtake Heal in any mono deck as well so idk if that is a good idea.
