When Staff of Domination was banned, it was one of the most widespread and iconic combo cards in the format. Banning it sent a clear message that turn four wins weren't the gameplay we wanted to see. These days there are plenty of scarier combo cards out there, and Staff of Domination has a valid role as a cool utility card. Neither of these would be enough their own, but together they provide solid reasons to unban the do-anything stick. Please enjoy Staff of Domination responsibly.

Trade Secrets is much like Limited Resources in that has some issues in a multiplayer environment. It isn't a problem when one player draws four cards and another draws eight. Trade Secrets is a problem when both players decide to draw 80 cards and effectively turn a four-player game into a two-player game. It just doesn't add enough to the format to justify the games that it single-handedly ruins.[/quote
