Multiple Lords of Change suffer from a lot of their value being tied to Infernal Gateway and Beacon of Sorcery. Perhaps you can do some fun things with Endless Spell spam to take advantage of their new auto dispel to recast them on new targets or use Omnscient Oracles rerolls with some combat buffs and swords to beef up your CC damage output.
Is it any good? Probably not. At the very least, an Omnscient Oracles list run as The Guild of Summoners would be hilarious. That’s a whole lot of chicken.
As a separate rules question, is there anything stopping someone from casting say, Darkfire Daemonrift, dispelling it, and casting it again with a different wizard? As far as I’m aware Endless Spells don’t explicitly share the usual restrictions for spells, save that you can’t cast it if you already have the model on the field. However I don’t have the book on me, so I might be missing something obvious.
