After having issues with Teron with other decks I created this one and got him on first try. The idea is to complete the quest asap and then controlling the board to prevent him getting back in game. Convincing infiltratot + psycopomp early is very strong. In late game after he casts army of the dead a plague of death will bring you back on track, and Vargoth can help you complete the quest earlier by replicating your cheap healing spells.
