@cluckyb The bottom seemed interesting enough, I just wasn't a fan of the top, mostly because I have seen (and made) way too many "Discard a card, gain a copy" clauses on cards, and they always just end up seeming boring. I would have liked the bottom on a much weaker, cheaper card.
I am really surprised Diviner won, but I guess I will follow SirPeebles example, though mine will probably end up a lot more boring:
Secret History of DivinerThis card started out as an on-buy attack, with the wording "When you buy this, each player (including you) reveals the top 2 cards of their deck, discards one that you choose, and puts the other back." I read the Secret Histories around that time, and realized that on-buy attacks usually end up being painful and unfun, and also, I had created an effect that would be really hard to balance. That got rid of the attack. Now, unfortunately, the sifting was boring, and overall too weak, so I finally came up with the idea of changing of it to the similar "When you buy a card". Thus, the bottom.
I now approached the top, knowing it had to have a +buy, and should probably be terminal, because this card can stack and become slightly obnoxious, and I didn't want it to be a "no-brainer" type of buy. I decided to go for +2 cards with the buy because it had been used less than coins, and it fit Hinterlands "Cycling" theme. I decided to cost it at $3 because on an average turn (one where you buy one thing) it is a Oracle that draws first, cycles second, and doesn't hurt anyone else, with a buy tacked on. I realize that is not its intended use, but it was certainly not a $5, and I saw no reason to prevent someone from opening double Diviner, especially since it was not strictly better than Oracle. The name was something I came up with last minute, and I am certainly open to changes.
There you have it, in case anyone was interested.
