Devoured by Zombies!!!
So how exactly do you capture the idea of zombies in a superhero card game? By turning things on their head and considering all of your opponent's characters as zombies, that's how! I hope this seems somewhat thematic for the Halloween event. If you have any suggestions or comments please submit them to me before the 21st of October. Here's the idea...
All characters in play gain the keyword Devour. This keyword's text is, "If an opposing character stunned by this character this turn would leave play, instead remove it from the game. That character is considered devoured."
This keyword can not be removed by card or character effects. Opponent's cards removed from the game this way go in a pile on your side of the table.
Once per turn, at the start of the combat phase, you may put the lowest-cost devoured character card into play. This does not cost any resource points. If you have two devoured characters that share the lowest cost, you may choose only ONE of these characters.
No recovery effects, KO effects or can-not be stunned effects can be played. This would encompass things like the keyword Evade, Quick Kill and Legendary Battles.
