Looks really cool! I like the mechanics of the Calamity happening if there are not enough visionary cards. It's a cool way to ensure that people are careful about destroying your clutches.
For the pecking order, if you only have 2 warriors on the board does that mean you resolve 0 visionary cards or 1? I think it would be 1 since it says empty slot and not empty column, but I just wanted to make sure.
But all in all looks like some really cool mechanics! Choosing the actions the turn before but letting opponents only see the first one is a really nice touch. Then they can decide if they want to remove it, although they don't know what action will be revealed next, very tricky!
