Hello. Welcome to the forums. I am glad that you enjoy this game. There is a mentor program if you need help in using the forums or the game itself. Well, for your first deck, I think there's a quanta issue. First, I would do - 3 drain life, -1 nightmare,-1 devourer, -1 darkness pillar,+1 steal(Always have a pair of steals
).+2 minor vamps,+2 aether pillar and 1 Dark Pendulum. Hope it helps.
For the second deck, U got too much going. That could be a problem. Since I think you would want the scorps, I think you should take out the shields and mitosis and add adrenaline. If one scorp has adrenaline then it's 2 poison counters and 4 dmg per scorp with adrenaline. Empathy Bonds are not necessary if you take out the mitosis. Your Heals would give you the healing you need.
If you need anything, just ask any of us and we will try to help.
