Shapeshifters are back in the upcoming Norse mythlogy-inspired Magic: The Gathering set, Kaldheim, and they are one of the 10 tribes of creatures featured in the Viking-inspired plane. The blue and green-aligned Shapeshifters of Kaldheim are from the realm of Littjara. . 

The Shapeshifters are Changelings (This card is every creature type), and most of the spells focus on copying creatures or spells.
