Nickelodeon has greenlit an animated series set in the world of its beloved Avatar: The Last Airbender. The new show, titled Avatar: Seven Havens, has a 26-episode order and will follow a new Avatar. The series will be the third in the Avatar -verse, following the original show and The Legend of Korra .

There are a few ways Seven Havens could approach an Avatar with the twin. The first could be similar to the Katara-Sokka dynamic from The Last Airbender, where one sibling is a bender and the other sibling is not. How would knowing your sister is the most powerful bender in the world affect your sense of self-worth and your relationship with her?

According to the announcement, MTG Avatar: The Last Airbender will be hitting shelves on November 21. It's unclear what the set will involve in terms of products, but we can probably expect something similar to the Assassin's Creed crossover last year. (Play and Collector boosters at a minimum, in other words.)
