1. Summoner's Gambit and Wealthy Benefactor have been rewritten so that they will always be up to date with the latest release, and have no chance to grant you unreleased cards.
2. Arena Seasons will no longer award promo cards for the time being. We haven't been able to keep up with the 25 day cycles. To compensate, the Standard Arena will now award additional Gems.
We're going to be running a contest soon to design a NEW Legendary creature. This will be your chance to get in on the design process and influence the future of the game! We will be running the contest on our official Facebook page, so if you're not following us yet, go there now and hit "Like".
Here are the new cards (click to see them full sized)!
