Yeah, true, I forgot about
Oona, Queen of the Fae. She's fine, but I honestly forgot about her, despite having run her in my list for about three years, because she's just another Pedestrian Finisher. Sure, she's efficient at her job, and closes out games right quick, assuming you have any mana to spare, but nowadays I feel like
Aetherling fills those shoes even better. She supports mill in the same way that
Nemesis of Reason does - that is to say, she's a standalone win condition, without any other mill cards in your deck. Even after having written so many words about her just now, though, I don't feel she's any more interesting than any other tap-out Generic Six Drop in those colours, though I wouldn't begrudge anyone for running her, as I did for a long time. Since I've made the swap, though,
Dragonlord Silumgar has been a lot more fun in that role.
This kind of ties into a feeling I've had over the last little while: I love multicolour
decks - most of the decks that have done well are three colours or more here - but I'm starting to hate most of the multicolour
cards. They rarely support
the themes and archetypes I'm trying to push in those colours;
efficient low drop creatures are just objectively worse draft picks than their monocolour cousins nearly all of the time; the strongest gold cards are increasingly of the
Value Good Stuff variety; many of the
planeswalker designs are niche or just uninteresting; as good as you make the mana in your cube (54 duals in 370 cards here),
two-colour gold cards still wheel forever. I love casting an
Edric or
Geist of Saint Traft as much as the next guy, but truly unique gold cards like that are too few and far between.
Maybe I'm just becoming a grumpy old curmudgeon, but I'm now of the philosophy that most cubes could benefit from running fewer multicolour cards, even - and maybe especially - the cubes that want to encourage multicolour decks.
