Mark Rosewater, Head Designer of Magic: The Gathering, released an article on Monday about some big changes in Magic’s future. Instead of three-set blocks, there will be two-set blocks with a big set first and a small set that expands on the world the big set creates. Standard, the most popular constructed format, will change as well. Instead of the last two blocks, Standard will be played with the last three blocks and there will be a rotation whenever the first set of a new block comes out. On top of this, Core sets will be wiped from the map entirely.
