Due to the Phyrexian’s impending victory in the war over Mirrodin, the Magic rules team has made a few changes in how the game works. Magic’s developers want the raw, aggressive ‘take no prisoners’ strategy of the Phyrexians to be mirrored in how the game is played. One of the more prominent changes is the complete elimination of the stack. First introduced when 6th edition was released over a decade ago, it has been decided that it is no longer needed. At this point spells and abilities will resolve based on a combination of whichever player does it faster and more importantly louder.

You can expect an official announcement covering this and a myriad of other changes later today. Today being April 1st wink wink.
