Kaldheim is a Magic: The Gathering set inspired by Norse mythology, introducing the plane of Kaldheim and its ten realms of gods, giants, elves, and snow-covered warrior clans. The set introduced Boast, a mechanic that rewards attacking creatures with bonus effects, and Foretell, which lets players pay ahead to cast spells cheaply later, echoing the theme of prophecy. Its saga-style enchantments and Norse-inspired legendary creatures made it a strong pull for both Standard and Commander players.
