I think you might be right about Burial and Falling away, but I'm not sure. Lampstand tends to turn up fairly often, between a semi-fast draw and Filling Z-Temple, but every once in a while I find myself wishing I could play a Falling Away on someone. Hmm...
I am hesitant, though, to take out Joiakim or Zechariah; I rely on them to be able to play the green enhancements in the deck. I've found that teal sometimes runs out of enhancements (surprisingly), and Plague of Frogs and Two Bears help immensely; however, Haggai is wierdly a common target for CM, and without him it can be hard to play them unless Zechariah or Joiakim are out.
