The new set of expansions will be referred to as the Year of the Raven, with the first set being announced "next month." I'm guessing one of the first two full weeks in March. Blizzard also announced tournament support in game, where Blizzard will handle deck validation and matchmaking.
And pour one out for three new inductees to the Hall of Fame: Ice Block, Coldlight Oracle, and Molten Giant. Molten Giant's base cost will also be reverted from 25 back to 20. I'm a little surprised by the Giant and Oracle's inclusion. I know Oracle got a TON of play in mill decks, but that seemed fine. I don't recall the alst time I Saw a Molten Giant, but I also hover around 18-20 each month. Ice Block was kind of a no-brainer.
