Design Goals: Replicate the draft-screwing design of the original Cogwork Librarian without making the card itself unplayable. A colorless Grizzly Bears in Cube is not generally very good, but it's a playable 23rd card. His ability to rummage away 2 cards is net loss, since you lose the Bartender as well. That's OK because between the card selection in-draft and in-game is "virtual" card advantage.
Inspiration: Cogwork Librarian

Some notes: We don't try to replicate proper Magic templating language in the rules text of cards. We do this to save space and make the cards more human-readable. Remember, you're probably real drunk when you're playing and the subtleties of the Intervening-If clause may elude you.
