Cards like Cloudshift , Ephemerate , Justiciar's Portal , Flicker , and Acrobatic Maneuver are pretty cool with Aurelia because they can be used for protection.. or for extra combats! After the first combat, flicker Aurelia. She re-enters as a new object that has not attacked yet this turn, so when she attacks during the second combat you will get a third combat, and so on. Better yet, these spells can be fished out with Sunforger. Eldrazi Displacer works in a similar way but is a bit more restrictive: you would need to activate the Displacer's ability in response to Aurelia's attack trigger so that her trigger will resolve last and untap her. Aurelia won't deal damage, but all your other creatures will get additional combats for every spent.

You need card draw big time. Consider Infiltration Lens , Farsight Mask , Knollspine Dragon , Wheel of Fate , Reforge the Soul , Geier Reach Sanitarium , Chandra, Flamecaller , Howling Mine , Dragon Mage , Skyline Despot , Mind's Eye , Outpost Siege , Stolen Strategy , and Vance's Blasting Cannons  ^Flip.

It's up to you to decide what's worth adding in. I would say you could use at least 5 of these card draw sources listed above in your deck

griffstick I’ve already got a few of those cards you mentioned in the deck. I have 3 wheel effects with Khorvath's Fury , Reforge the Soul , and Memory Jar as well as an equipment to draw me cards with Mask of Memory which is generally a draw 4 discard 2 with Aurelia. I also have Geir reach and Mikokoro for the lands that draw cards. Then I also have 4 tutors that get Mask from the deck and 1 that could get Mask or Memory jar.

Only 11 plains w Emeria seems greedy.
