Kormus Bell turns every Swamp on the battlefield into a 1/1 black creature — pair it with Urborg, Tomb of Yawgmoth and every land in the game becomes a creature, which is either a board-state-defining threat or a global Wrath waiting to happen. The four-mana artifact earns its slot in any deck that wants to mass-kill lands, generate tokens off land-creatures, or feed a slugger like Toxrill, the Corrosive a buffet of Swamp-creatures to slime.
Best Commanders
Commanders with the highest synergy
Toxrill, the Corrosive
Toxrill, the Corrosive puts a Slime token on every creature it doesn't own at end of turn, and Kormus Bell converts every Swamp into a valid target — combine that with Urborg, Tomb of Yawgmoth and opponents watch their entire manabase get slimed out of existence while Toxrill generates a flood of 1/1 tokens you can cash in for cards.
Maha, Its Feathers Night
Maha, Its Feathers Night gets +X/+0 equal to the number of lands opponents control, so Kormus Bell animating those lands into creatures doesn't shrink Maha's bonus — it just means those lands can now be swept off the board en masse, clearing blockers and ending the game in the same action.

Kormus Bell is a Commander card through and through — the four-mana setup cost is acceptable in a 40-life multiplayer game where the Urborg, Tomb of Yawgmoth package has room to assemble, but it's far too slow and narrow for Legacy or Vintage, where it sees essentially zero competitive play despite being legal in both. In Commander, the ceiling is legitimately high: global land animation enables mass-land destruction via Wrath effects, synergizes with every slug and aristocrats payoff in black, and can lock opponents out of mana entirely in the right shell. Outside Commander, treat Kormus Bell as a curiosity — legal in Oathbreaker but the same speed concerns apply.

Current price
$4.99 cheap tier
At $4.99, Kormus Bell sits at a fair price for a niche artifact with a loyal Commander audience and no reprint pressure in sight. It's cheap enough to throw into any black deck experimenting with the Urborg package without much hesitation, and the price reflects its narrow but real demand.
