When I first made this deck, Aether Hub was in standard and the price was a little high. Now, it's looking like a great option for a deck that only needs some of its colours for one spell.
Looking at other energy cards to support it, Aether Meltdown, Rogue Refiner, and Shielded Aether Thief look great. They help protect you, and enhance draw as a way of getting at Tamiyo or as a way of winning after the emblem drops.
Adding more to the card draw theme, Etched Oracle looks pretty nice, especially as our ramp becomes less important and Crystalline Crawler gets more expensive. It's also great with the proliferate guys.
Another budget change is the removal of two of our Tamiyos and one of our Trench Gorgers. The Gorgers are because the deck has a harder time supporting three 8-drops now, and Tamiyo is mostly because her price is going up.
I'm trying out two new singletons as well. Remand is a nice counterspell that supports our draw theme, and Elixir of Immortality is a nice backup and stalling piece. The one final change I'm experimenting with is Azorius Charm instead of Simic Charm. The draw and disruption seems to be more of what we're going for here.
All of this pulls the deck a little bit more into blue, which I think means I can pull out Navigator's Compass. I've made some adjustments to the mana base, including adding some dual lands that I own. They're easy enough to replace, and on a tighter budget, you could add the compasses back in.
