Featuring 285 new cards, the Viking-themed Kaldheim features new mechanics like Foretell and Boast, as well as returning mechanics such as Snow, Changeling, and Modal Double-Faced Cards. The set also features tribal themes that represent the 10 realms of Kaldheim.

However, some players reported several bugs in the game, and it looks like the MTG Arena developers have already fixed the issues. They released the MTG Arena Patch 2021.01 notes to sum up all the new events, gameplay notes, and bug fixes with the release of Kaldheim.

Prior to logging in, check out the MTG Arena patch notes below:

Aegar, the Freezing Flame
While on the battlefield, MTG Arena will override the Auto Assign Combat Damage setting with Aegar, providing a prompt for players to trigger Aegar by adjusting the default combat damage assignments.
Alrund, God of the Cosmos
Alrund, God of the Cosmos will prompt players to choose a card type. By default, the only card types within the deck will get listed.
Ascendant Spirit
Abilities on Ascendant Spirit are highlighted if the Spirit has the necessary creature type for an ability.
Cosima, God of the Voyage
A voyage counter is placed on Cosima, God of the Voyage whenever a land enters the battlefield under your control and Cosima is exiled. A player can choose not to put the counter on Cosima and have it return to the battlefield with (X) +1/+1 counters on it and draw (X) cards, where (X) equals the number of voyage counters.
  • Take Action: Card remains exiled, you put a voyage counter on it.
  • Decline: Return Cosima to the battlefield with X +1/+1 counts on it and draw X cards, where X is the number of voyage counters on it
Haunting Voyage
Haunting Voyage will list creature types in that controller's graveyard when prompted to choose a creature type.
Niko Aris
If an opponent's Niko Aris deals two damage toward tapped creatures with their minus-one ability, the ability on the stack will have a count badge with the number of cards your opponent has drawn during that turn with an X2 modifier to clarify that the ability will do twice that much damage.
Old-Growth Troll
An update was applied to Auto-Tap, where it's more likely to leave an Old-Growth Troll enchanted forest untapped.
Auto-Tap and Snow sources
Auto-Pay will maximize the amount of mana from Snow sources for spells. Auto Tap will pause and give the player a chance to manually pay for the spell, as long as that player has untapped Snow sources.
Glittering Frost
There's a known bug affecting Glittering Frost where manually tapping it will cause the game to freeze. The MTG Arena devs are working on a fix. But until it's resolved, it'll affect gameplay within all formats.
Boreal Outrider
A pay with Snow button will appear when Boreal Outrider, even if it provides no effect.
