I was thinking if I should put a third unit in my pure shadow pvp deck (not shadow-shadow-frost) along with Ashbone Pyro, Cultist Master and was not sure what unit exactly out of these options:
Brannoc and Unstable Demon are excluded for now. At the moment I have 5 cards on my tier 3, 2 units plus Evocator's Woe, Voidstorm and questionable Soulshatter.
Thank you for the insight.
