This is my current WIP TJS Lifesteal deck.
I aimed for three core mechanics:
1.
Unseen Commando Most of the unit cards have two or more Battle Skills to trigger his ability.
2.
Oathbreaker Most of the units have Lifesteal to trigger her ability.
3.
Dread This card is amazing and feels like an Upgrade of
Piercing Grief. If not canceled by your opponent you can trigger two of them infinitely every round.
As this will be fine tuned in the future I'd like to hear your thoughts on the way!
Edit-1: I added Vara to answer for this nasty Aegis...
