Magic The Gathering The Lost Caverns of Ixalan is the ninety-eighth Magic expansion. It will be released on November 17, 2023. 

The Lost Caverns of Ixalan is Magic's take on the “Underground World” trope. It is not a traditional return set: R&D was making an underground set, and Ixalan felt like the best fit for it. It wasn’t the other way around. As such, it is not a mechanical return to the previous set. The set will have Dinosaurs, Merfolk, Pirates, and Vampires, but it won’t be factioned or particularly typal. Thematically, it is more of an action/adventure set.
