I just released 1.5.51.006, which contains a first look at Shadows over Innistrad. Please keep in mind that there are still some card bugs that are being worked out, although feel free to post any you find here (until the next Beta is released at least). Hopefully we'll get everything smoothed out soon, but meanwhile enjoy building and playing with the new cards.
Also included in this release is an update to the Collection screen for Planar Conquest. I've changed it so exiled cards now appear separate from your usable cards, with tabs at the bottom of the screen to switch between your usable collection and the exiled cards. Now, exiling cards will move them to the other tab and retrieving them will move them back.
