Wizards of the Coast recently revealed the new cycle of six rare Magic: The Gathering modal double-faced land cards from the upcoming expansion Zendikar Rising. The cycle of six pathways is a mix of lands that produce ally and enemy-colored mana, so there are only four missing dual combinations that are not featured in Zendikar Rising. However, it looks like fans won't have to wait too long to get the other four pathways.
When a fan asked Mark Rosewater asked about the missing four rare MDFC lands, the MTG Head Designer confirmed on his Blogatog: "The other four are coming very soon". That response suggests that the other four might be released in one of the 2021 Magic sets.
You can check out how the modal double-faced cards work in this mechanic spotlight:
Zendikar Rising is set to release on September 25, 2020; it will release on MTG Arena on Sept. 17.
