I made this for something fun to passively watch while enjoying some Jazz Cabbage. I was surprised on just how well it does.
If you have out a Prize Sow and play a Severin of the Dark. Moving forward any time a unit dies, automatically a new Piercing Greif is created. This includes during your opponents turn as well, which might be a bug because it seems a tad over powered. Once that combo is down you generate life every turn and you can either end it with brute force, or use Xenan Fanatic to finish the job..\\
Once you hit 7 power, You don't need to play anymore, save it if you don't have Prize Sow to generate Piercing Griefs. Try to save on Sow on the early game, not much benefit running it early, try to save it for a combo or at least have a Dark Return to bring it back, Sow is critical for the deck to work as intended.
Running one faction, I believe this would be a good starter deck to make on a budget for enhancing your grind experience with something new to play with while you do it.
