I recommend evaluating your card for best to worst case by valuing it at several potential grades
Whenever a player Earthbends, they choose a target land they control
Those seeking to do slightly less terrible things to their friends during casual commander games will find repeatable mass blink effects that net you cards (Cloudblazer, Unquestioned Authority, etc.), the ability to get around mana costs through the Manifest mechanic (Cloudform, Scroll of Fate, etc.), or even double mana from mana rocks is plenty sufficient when it comes to generating incremental value
Foil prices, meanwhile, have absolutely soared in the past few weeks
Meanwhile, Thermokarst gives you a life sometimes, but theyre pretty much interchangeable cards and its much cheaper to buy
Not an Exodia Card
