This is Archenemy: Negan.

This is designed to be played with the cards from the Secret Lair: The Walking Dead. This is a 1 v 4 (Negan vs. Rick, Michonne, Glenn, and Daryl).

The rules are the same as prior archenemy sets aside from one key difference. There is a neutral zombie horde that spawns Walker tokens each upkeep. Some schemes interact with this horde by slowing it down or speeding it up. It must block if attacked. It must attack a random player during its turn. It always takes its turn last.
