Chaos

Chaos (Visual)

When you really need to be That Guy.
General Mayhem cards
Random cards
Coin Flip cards: not a complete list; I removed some of the really terrible ones
Not including Die Rolling cards, as those are easy enough to find. (All the legal ones are in AFR/AFC.)
Silver bordered cards and Mystery Booster playtest cards also fit into this category, if your playgroup allows those.
