This is something of a modern take on Desert Twister. It kills most permanents, and can often 2 or even 3-for-1 an opponent, sticking around after its initial effect to possibly deathtouch and kill another creature. It's a fine creature in slower decks and gives green mages some control elements to work with. It's not as situational as cards like Tranquility or Naturalize, and can hit lands if there are no other targets and you just want it on the field. Furthermore, this is excellent with Momentary Blink and other recursion effects.
