Kaldheim is both a plane (self contained world in the MTG universe) and the name of the first Magic expansion in 2021.
Kaldheim is a Nordic themed world. So you can expect Magic’s take on Norse mythology, vikings and other similar tropes.
We first heard about Kaldheim back in 2009. It was featured on a Plane card (from the Planechase set).
Each Kaldheim Collector Booster contains 15 cards + 1 token:
	
1 foil showcase / borderless / extended rare or mythic
	
1 non-foil showcase / borderless rare or mythic
	
1 rare saga or exclusive card or Kaldheim Commander card
	
1 non-foil extended art rare or mythic
	
1 foil showcase uncommon
	
1 non-foil showcase uncommon
	
2 foil regular uncommons
	
5 foil regular commmons
	
1 foil snow basic land
	
1 foil double-sided token
So in total, you’re getting:
	
4 rares or mythics
	
4 uncommons
	
5 commons
	
1 foil snow basic land
	
1 foil token
All of these cards will either be in foil or have special art – maybe even both!
