So, Charak fucked up with the Chaos Emissaries. Therefor, we overhauled the entire archetype (except for Chaos Caller, and only some slight changes on Lux and Umbra) to make them a lot more focused and quite frankly, better. This'll be the entire thing, some cards have been renamed and some even outright removed.
