Well, I went ahead and threw together a first draft for an Enchantments/Enchantresses deck with Kenrith Golos at the helm. I haven't tried this out yet, so I'm not entirely sure how well it'll work out, but at a glance it seems like it'll be fairly solid. I've got all the good enchantresses, I believe. The ideal game would be to start with some ramp, then just start chaining enchantments together that build steady presence and make it harder for opponents to interact with me, until finally going for a win con. If I need it, Kenrith is there to drop early and just draw cards, reanimate a creature, gain some life, whatever. Golos is there to find Serra's Sanctum or Field of the Dead, or just colour fixing, and as a great mana sink to just dump a bunch of stuff on the table.
Main ways to win currently are angel tokens from Sigil of the Empty Throne, or going wide with either Starfield of Nyx or Dance of the Manse, or lastly just a nice big Villainous Wealth after getting a bunch of mana with something like Serra's Sanctum or Mirari's Wake. No combos in here at the moment, but I might put one or two in for backup.
The only enchantments deck I've played in Commander before was a 75% Zur the Enchanter deck, which played out pretty differently from how this one will. I'd love some comments/suggestions from people with more experience with the archetype!
