Just a day ahead of the official previews for Kaldheim, Magic: The Gathering Arena streamer Amazonian has revealed eight artworks of realms from Magic's Norse mythology-inspired world. These artworks will most likely be featured in nonbasic land cards that Wizards of the Coast will soon reveal.

These cards will most likely be duals land that each represent a color combination in this order: WU, UB, BR, RG, GW, WB, UR, BG, RW, GU. Last month, Mastodon already revealed that the four MDFC lands will also be in Kaldheim.
In addition to these new Kaldheim artworks, Amazonian also revealed a new Saga card from the upcoming set.
The official previews for Kaldheim wil continue on January 7, so expect Wizards to reveal more cards starting tomorrow.
Kaldheim is set to release on February 5, 2021 for tabletop, and Jan. 28 on Magic Arena and Magic Online. The set will be followed by Strixhaven: School of Mages, which is set to release sometime in Spring 2021.
