I have a pen flingers quest shaman deck that generates lots of spells especially 1 cost spells. I once transformed every single minion the Rez priest put down. They double copied a vaargoth (which I was waiting for) and I lobbed 3 devolving missiles at them (and somehow still missed a vargoth). Since his guy was divine shielded tho, they couldn’t kill it and I hexed the next turn. The I got plague murlocs off one of the elementals and they quit.
It was very funny.
If I met one in real life, I’d say with a big stick, repeatedly.
I’d like to run into one of the Khartut or Infiltrator lovers with my Pogo deck. I recently found out that my deck does let me put a double-digit number of Lazuls into my deck, even though she didn’t start out in my deck. I suspect the opponent didn’t like it when I had a line of three Lazuls staring him down as he or she left the game. Replicating the opponent’s Khartut or Infiltrator might feel even better.
I also like to see khartut defenders it helps me otk my opponent. I can play trueaim crescent, wand maker, hero power and a buffed trampling rhino (if they are full health you will need the rhino to be 17 attack when going into a khartut defender).
Putting crap in their res pool is also hilarious. 
Two words: doomsayer + treachery 
I play ReZ Priest every now and then. The key to winning against it is pressure. Keep up a lot of pressure and never let the game go on long.
Huh, I hadn’t thought of that one. Nice.
Esp if you get a doomsayer in there.
