I can't be bothered to search all these uninformatively titled cards to see if this is already been suggested, but what about a card that randomly switches the positions of all the cards in your hand? I'm thinking of something on par with the other 0-cost discard cards, but most useful for cards like Mirror Golem where you want to get it lined up with specific opponents cards.

Here you are.

...why aren't these things showing up on my card listing?

You can use these cards only when you reach respective level. It was made because Mojko wanted to do some kind of tutorial. Max card level is 10, and you can reach this level by playing against AI opponent.

Since this isn't in the deck building section of the Help, where is it categorized?

Try to look into Cards section.
To be honest, I haven't tested this tutorial system, and I don't remember any feedbacks about it, so I even don't know if you'll be able to see all cards before level 10.

Ok, now that I've gone and read it, that's terrible. I'll post this link here and in the thread in which I alluded to it:
