If it doesn't clone it, I would copy and paste it onto the clone stack, then after you're done add the clone stack back in. The only wildcard I can recall is that monster specific resources don't get cloned, because you do have a limited draw per time you face. The deck is rebuilt each time you trigger a showdown.

I think this is a good explanation of the mod:

In the video he took the hunt events deck out of the white lion box. Please do not do that. He also placed the White Lion figurine from the stand on the showdown map. This figurine must be placed center in the back either in the hunt or the showdown spot. When you do, the game will set up most of the things you need automatically. E.g. when placing it on the showdown spot, the game will take out the hit location, AI, Terrain cards and the actual showdown figurine from the White Lion box. If you took anything out manually, there are bound to be scripting errors.
