Drawn from Dreams
Look at the top seven cards of your library. Put two of them into your hand and the rest on the bottom of your library in a random order.
Dig Through Time with the mana cost and timing restrictions of Jace. Seems playable for the power of the effect and a cost we can pay in Vintage. Jace is on an all time low right now for being expensive though, so I don't know. Also Jace's -1 seems pretty important.
EDIT: has a big difference from Dig for Oath since it's puts on the bottom randomly.
