Magic 2015 was released on July 18, 2014. Magic 2015 made the second major change to the card frame in Magic's history (the first being in Eighth Edition). Changes include a slight font change (Starting with Magic 2015, an in-house font known as Beleren will be used rather than the Matrix Bold font), the addition of a holofoil stamp in the bottom center of all rare and mythic rare cards, a slightly narrower black border, and a redesign of the collector's info at the bottom of each card. The new border will make it easier for machines to read the cards, helping to prevent mispackaging. Advertising for the set featured the planeswalker Garruk Wildspeaker, with a tagline of "Hunt Bigger Game." Magic 2015 includes the mechanic "Convoke", which originally appeared in Ravnica: City of Guilds. This mechanic allows a player to use their creatures to help cast spells with Convoke. It also includes 15 cards designed by notable non-employee Magic fans, such as Richard Garriott, George Fan, and Notch, some of which also appear in Duels of the Planeswalkers 2015.
