The Lantern of the Keeper

When The Lantern of the Keeper enters the battlefield, if you control both Dusty Crevice and Keeper of the Dusty Crevice, you may equip it to Keeper of the Dusty Crevice.
Whenever Keeper of the Dusty Crevice deals
combat damage with Lantern of the Keeper equipped, put a crumble counter on each opponent
who took damage. Then if an opponent has two or
more crumble counters, that player loses the game.
If you control Dusty Crevice and have a crumble counter put on you, you lose the game.
