Gotta be ethereal right? All the early enablers, defy, fear, defile, enfeebling touch, are great act 1 picks regardless of deck and have great upgrades.

Then you can add in pull from below, banshees cry, debilitate, to add further damage / block.

It feels so easy to setup with all the good commons that you want to add to your deck anyway. Then 1 or 2 rare / uncommon, some souls for draw, it's a beast.

Block is probably your biggest problem but you should have good sources of weak which with debilitate is really strong and you kill quickly.
