Today on Weekly MTG, Wizards of the Coast R&D member Ian Duke announced that Mythic Championship London’s formats will be Modern for the Constructed portion and War of the Spark Draft for the Limited portion.
Although the Limited portion of the Mythic Championship will feature War of the Spark, the Modern portion of the event will not allow cards from that set to be included as they will not yet be legal in the format (and players won’t have way to obtain them before the event, anyway).
Mythic Championship London takes place from April 26th to 28th in London, England, which coincides with the pre-release weekend for War of the Spark, a decision that caused some controversy last week for local stores in the United Kingdom.
