The only thing I can add to this thread is to say that my (brief) stint playing a Volcano deck definitely taught me a LOT about the value of strategic passing. Passing at the right time is an incredibly important skill, Volcano deck or not.
Looks quite solid. But wait, why not Robe Of Lightness? And there might be a problem with this build: you have literally no answer to your enemies' Dimensional Traveller and/or Hover ---- which isnt ... that rare in some Burfft teams. Also, in maps like Central Proccessing Unit, a human burfft team (Not dwarves - you know why) could outrace Volcanos due to their ridiculously high stability, at least compare to other mage builds.
