Magic Origins was announced February 8th, 2015 during Pro Tour Fate Reforged. The set contains 272 cards, which is 3 more than the current default for large sets (101 Commons, 80 Uncommons, 55 Rares, 16 Mythic Rares, 20 Basic Land). An additional 16 cards appear in the sample decks. As a first since Alpha, this Core Set features two new mechanics. R&D considers Magic Origins not to be the “last core set”, but a “new beginning” relating to the start of the Two-Block Paradigm and a new treatment of the storyline. The latter involves telling coherent, in-depth stories about the characters and carrying those out over story arcs across multiple sets. To enable this storytelling, there are more new cards in this set than in previous Core Sets. More than ever, Magic Origins is strongly integrated with its digital counterpart, Magic Duels. We see the main characters depicted before and after their planeswalker’s spark ignites. The design of the cards and mechanics mirrors this for the players, as a kind of “leveling up” to their full potential. This is achieved by double-faced cards with one side featuring a legendary creature, and the other side featuring its planeswalker incarnation.
With Magic Origins, Wizards of the Coast experimented with a new mulligan rule: any player whose opening hand has fewer cards than his or her starting hand size may scry 1. After Pro Tour Vancouver, it was positively evaluated and implemented everywhere else.
