It's tough for me to get rid of the Poison, since it helps when the creatures get stalled (and mostly why I put it in there), the Mummies are useful for rush, and Time Reversal works well to Pharaoh them, and the Ghosts just do some straight-up damage. Everything works pretty well together as far as I can tell. I guess the only complaint is that it's not as fast as mono, but it has deterrents to certain things that would just otherwise lock it down.
