spjspj - Add Rich Man Cube draft. This is a variation on the Rich Man set draft. It still (like cube) shouldn't let there be more than one copy of a card in the draft but will give each player a new pack from the cards that haven't been picked already each time. Allows 2 player cube drafts to be playable.
