As of the Oops, You Did It Again expansion, there are 64 factions, which can combine to form 2,016 unique pairs of factions.[1]

Each player shuffles two factions together to form their deck of 40 cards. Every faction typically has 20 cards with some combination of minion cards and action cards. Factions have a typical structure, although there are many exceptions. The typical structure of a faction's cards is the following:


Ninjas have a typical faction structure

  • 10x Minions (total power 30, average power 3):
    • 1x Power 5 - the "King Minion"
    • 2x Power 4
    • 3x Power 3
    • 4x Power 2
  • 10x Actions:
    • 2x Some Action
    • 2x Some Action
    • 1x Some Action
    • 1x Some Action
    • 1x Some Action
    • 1x Some Action
    • 1x Some Action
    • 1x Some Action

Factions with a different power distribution (while still retaining the regular 1x, 2x, 3x, 4x structure) include: Aliens, Dinosaurs, Wizards, Zombies, Bear Cavalry, Ghosts, Killer Plants, Elder Things, Shapeshifters, Giant Ants, Elves, Halflings, Mages, Orcs, Thieves, Changerbots, Teddy Bears, Sheep.

Factions with a different structure include: Robots, Innsmouth, Minions of Cthulhu, Geeks, Princesses, Mythic Greeks, Superheroes, Astroknights, Star Roamers, Rock Stars, Smash Up All Stars, Itty Critters, Kaiju, Magical Girls, Mega Troopers, Disco Dancers, Vigilantes.

Each faction has a special gameplay mechanic that is common among the faction's minions and actions. For example, Zombies come back from the discard pile, Ninjas specialize in destroying other minions, and Ghosts gain bonuses from having only a few cards in their hand.

Each faction has two associated bases, released in the same set. You might say that each faction has two bases, although the relation is mainly thematic: If a faction is not chosen, its associated bases can still appear, and some bases don't really give an advantage to their associated faction, e.g. Jungle Oasis (the Dinosaurs can easily score it, but only for 2 VPs), Temple of Goju (by themselves, the Ninjas won't be able to get back their highest-power minion), Cave of Shinies (the Tricksters can destroy other players' minions, but they definitely don't want to do it there, and their own minions are usually protected against destruction), The Dread Gazebo (the Ghosts don't get any advantage from it and they even have a play-on-base action),...
