Magic Presents: Heart of the Mountain 9/10/2026 @ 6pm

Battle for control of the Heart of the Mountain in this special casual Commander event featuring a unique Arkenstone gameplay mechanic!

Format: Commander
Play Level: Casual
Entry: $5

How It Works

The first player to deal combat damage to another player claims the Arkenstone emblem.

From there, the Arkenstone is up for grabs! Deal combat damage to its current owner to take control of it for yourself. Holding the Arkenstone gives you special bonuses—but it also puts a target on your back!

Each turn you control the Arkenstone, increase your ownership count by 1 during your upkeep. Your ownership count stays with you even if another player steals the Arkenstone.

🏆 Reach an ownership count of 3 and you win the game!

Participation Promo

Each player will receive the Heart of the Mountain participation promo card for participating, while supplies last.

Bring your favorite Commander deck and see if you can claim the Arkenstone long enough to become King Under the Mountain!
