(Note: This is a /r/CustomHearthstone post that I finally got around to sharing here.)
Hey everyone! I'm proud to announce that after over a year and a half of design, I've finally finished my custom expansion, March of the Burning Legion.
March of the Burning Legion is an expansion based on the Burning Legion's many invasions of Azeroth, featuring characters and events mainly from the War of the Ancients and the Second War. It features 144 new cards and eight Missions based on the Black Temple raid in World of Warcraft: The Burning Crusade (Missions to come soon).
Among some of the highlights of this set are the addition of 49 Demons (both neutral and class cards), increased prevalence of the Immune mechanic, and awesome Legendaries such as Queen Azshara and Kil'jaeden, the Deceiver (and Ragnaros, Lord of Fel).
Special thanks to the /r/CustomHearthstone Discord, without which none of this set would be possible. And of course, thanks to HearthCards (and Nikko!) for making card creation itself possible.
