Magic: the Gathering has officially announced its next major "Universes Beyond" crossover, bringing Avatar: the Last Airbender to the card game.

The trailer features the MTG logo doing some impressive airbending, with the familiar sounds of the show’s original opening in the background. And the caption understood the assignment, as it begins with the well-known line “Long ago, the four nations lived in harmony, but everything changed when the Fire Nation attacked.”

Magic: The Gathering’s Final Fantasy crossover set is one of the most anticipated expansions of all time. Here’s everything we know about it.
