Today Wizards has announced the unbanning of a couple of cards in the tournament scene. The main announcement is the unbanning of Valakut, the Molten Pinnacle from Modern. According to the article:
Recent Modern tournaments have been diverse, with no deck dominating the metagame. Since Modern is a non-rotating format, banned cards never rotate out. The DCI is unbanning a card to see how that affects the format. We looked for cards that were on the initial banned list for Pro Tour Philadelphia. We wanted a card that would not easily slot into an existing top deck and also wanted to enable a deck with a different play pattern than the current top decks. After examining the options, Valakut, the Molten Pinnacle was selected as the card to unban.
If you were thinking about trying Valakut out, it is still a relatively cheap card to buy and may be worth getting your copies before they go up.
