All around, they work pretty much the same as if you were to set up (or rig) your Deck. I'm not going to enforce the use of an RNG, but if you want to go that route, be my guest. You basically pick and choose the cards you use and when you use them. When going against an NPC, it's easy. When against a player, you have to do a collaborative post. When we get the IC up, I'll pull up a collaborative document site to use. It's really easy.
