This seems quite nifty. I wish it was able to sweep tokens, but being able to hit one drops right off the bat is great against aggro, and being able to deal with problematic 2-drops like Survival / Jitte / Oath of Druids is nice. Definitely interested in this one, will try and find space.
If you're a fan of Ratchet Bomb and / or Powder Keg, you'll definitely like Blast Zone.
