And there it is.

one of the things I like about donation cards is that they let me test certian ideas/etc in a relatively controlled context. This card is cheaper than an ivory library but it doesn't let you mill your opponent, but it also alternatively works as a charm, but it's also unique. How do you cost something like that? Well, if this is too powerful then the worst case scenario isn't so bad - it's not publically available, remember. But if it's too weak, all that happens is that I end up getting less money
