As someone who used to play Magic: The Gathering and hopes they could get back into it, I can assure you all that the game is extremely metal. Now Magic: The Gathering is introducing their explicitly metal-themed, Viking-inspired set Kaldheim by way of Mastodon.
The band made the below video to introduce a handful of new cards, and discuss their new album that they're recording right now!
Magic: The Gathering also made a pretty kickass Kaldheim playlist, which you need to hear.
