Magic: The Gathering – Mercadian Masques

The crew of the flying ship Weatherlight escapes the Dark Lord's plans and finds itself trapped on Mercadia, a world of secrets. Nothing is what it seems in this set, which is all about instant gratification. Mercadian Masques is the first set to include premium basic lands. It also features mechanics like Mercenaries, Rebels, and Spellshapers. —description from the publisher
