With the new CubeTutor functionality, this post is no longer very useful, and I do not know of anywhere that points to it. That said, I won't bother to delete it.
This blog post catalogs all the custom cards for the FroSoCube. They appear in the linked Imgur album, and in text format below. This is intended to be a living document, although in practice I will probably only update it in batches.
Note: The album currently includes a copy of Worldknit, which, while not a custom card, is the second Worldknit in the cube.
