In 2014, Magic: The Gathering fans wanted one thing above almost anything else.

From its very inception in 1993, Magic has relied on five colors to define the game. You can play as a blue wizard and use deception and trickery to undermine your opponent's every move, or play as a black wizard and manipulate the very nature of mortality (or be a blue-black wizard and do both at once). But for over two decades, as Magicgrew increasingly popular (and increasingly complicated), its publisher, Wizards of the Coast, resisted the urge to introduce a certain subset of color combinations — that is until Khans of Tarkir launched in the fall of 2014 and changed Magic the Gathering forever.

It happened almost by accident. Mark Rosewater, head designer for Magic: The Gathering, tells Inverse that Khans of Tarkir’s iconic three-color combinations were never the original plan. They weren’t even introduced until “four months into design.”

“The interesting thing about the wedges,” Rosewater says, “is that we backed into the wedges.”

Inverse spoke to Rosewater and his collaborator David Humpherys to unpack the origins of Khans of Tarkir, what they wish they did differently, and Magic: The Gathering’s plans to return to the set (and its wedges) in 2025.
