Scalding Tarn

We know how much Commander/multiplayer players love their card draw

Copy a mutating Gemrazer while it's on the stack, and you'll be destroying three artifacts or enchantments the first time, and two for each mutate after

For example if youre using a cheap 2-cost Commander such as Kwain, the Itinerant or Yuriko, the Tigers Shadow, then you might find 37 Lands too high as you dont want to hit too many in your draws

This commander doesnt need to be in a sacrifice deck to be good, but it can fit the mold

This deck gives up creatures for artifacts that function as elementals, which means targeted removal can risk you overcommitting to elementals, only to be left trashless at just the wrong moment (yes, having no trash is a bad thing)
