Maybe toss him a bone and let him hear the dead?
He is an undead monster or something anyway. As it is he doesn’t have the escapes of the Possessor or the help of Evil like the Sorc. Also he gets killed/outted by psychics fairly well since he can’t claim many things without the dead telling on him.
Just spit-balling. Possessor feels good and Sorc seems able to win now, but Reaper still feels like the hardest win in the game to me.
