Shadows Over Innistrad is that very expansion and is out right now in the App Store for free.

It features a brand new story about a power struggle between good and evil. You'll face brutal werewolves in dark forests, noble vampire families vying for power, and the monstrous creatures created by mad scientists in secret laboratories.

More importantly though, new cards have been added. There are over 300 of these and they're based on Magic: The Gathering's Shadows Over Innistrad and Oath of the Gatewatch sets.

There's much more on offer here like new skill quests but you'll have to head on over to the App Store to check it all out.
