Guys, come on, the priority skip is bad, but you don't include 6 cards and keep them in your hand to improve 2 Abbots. I still like the Bonesaw/Esperzoa idea for the repeatable Prowess trigger. Esperzoas can replace Umara and Bonesaw does a similar thing than pumpspells. Easy enough, I'll give it a try.
I have something to share of my own. Izzet Mill with lots of control, draw and brainz. I had this in mono blue, but pure bounce is not enough against aggro - the Izzet version is much more resilient.

Evolving WildsIt's important to have spells for every converted mana cost, so you don't need to manipulate
Brain in a Jar and can use it efficiently at least from 3-5 cmc for counters and draw. Having all purpose counters ready for 1 mana is insane and so is the draw power.
The deck doesn't desperately need Tutelage to win. I won many games on the back of
Fevered Visions, with massive card draw for complete control and a persistent 2-4 damage a turn.
Thing in the Ice is really good here, too and can double as a defender, boardwipe and wincon.
Chandra, Flamecaller can be an instant win with
Sphinx's Tutelage or a boardwipe if you need that. You rarely use her for damage, but if
Fevered Visions did some work that might also be dangerous.
Rise from the Tides can be a 1-shot wincon, if you got 6 counters on your brain and can bring the Zombie Apocalypse on their end step.
Lightning Axe can enable the madness of
Just the Wind and
Broken Concentration, but it doesn't have to. There's enough draw power to support a regular discard.
The single Plains and Evolving Wilds are obviously there to buff up
Radiant Flames if needed. The sweepers are important against the really fast aggro decks that curve out at 2-3 cmc. You can take some early damage and you can slow them down with single target removal, but eventually you'll need one of the sweepers.
