Deck I am tinkering around with for the new Promo, requires a lot of Shadow and Primal. The deck has been working really well so far. This is not a finished product so suggestions are welcome.
The game plan is to win via At Any Cost, stealing all their units, beating in with Davia/Icaria, or demoralizing then into surrender via card advantage and making removal difficult to use on you. Acantha is largely just fodder that can also run away with the game. Discover Talents does everything from being a power, to getting a spell, or getting a hero, and since we are only running heros, it's a perfect fit. Exploit, Discover, strategize, and forbidden research allow you to hit all your power drops and cycle through your set up. Don't be afraid to discard or shuffle away high drops or anything you won't need for a while, there is enough draw to get it back.
