Saving my favorite for last! Shadow Mages of Shadow Era have often been consider the weaker faction because they generally relied on a later game style deck, while humans relied on a faster deck. The Shadow Mages in Call of the Crystals and Dark Prophecies typically revolved around Tome of Knowledge, Shadow Knight and Sacrificial Lamb. Shattered Fates bring lots of new toys that work really well including new Undead tribal things, Amulet of Conjuring and Flameforged Gauntlets. In additional, Gravebone received some boost with Crystal Shards and Falseblood Cultist.
