I appreciate your feedback, but I have to disagree. Creeping Chill may not be very good, but I would like to argue that it has some utility in that it dodges most hate, and can help you get your opponent down to hasty Bloodghast range. I have to admit Noxious Revival does look fun, but it also less optimal than many other options. Firstly it can be pretty slow, and it gets hit by Mental Misstep. Also, if I am worried about Wasteland and such, then I can just run some number of Life from the Loam or Petrified Field (which I am already doing). Now for Dread-Return, I think that it is an amazing card in Dredge, but I would not really consider it to be spice, as it is in probably 90% of builds, and it tends to be quite weak post-sideboarding. If you have any counterarguments I would love to hear them!
