Jace, Architect of Thought for swarm decks, card advantage, and ridiculous power with Doubling Season, theoretically Tamiyo, the Moon Sage could reach equal levels of shenanigans.

Have you considered Gilder Bairn for this deck?

Have you considered Sarkhan Vol or Xenagos, the Reveler instead of Kiora? I really, really do not like her in this deck.

Sorry for the delays in changes/updates guys...I ended up getting diagnosed with skin cancer; however had a succesful surgery and have spent the last couple weeks healing up! Between that and the birth of my baby boy; it's been a lot to deal with the last couple months (most of it good though!) I have no room to complain. I have a great life. I just didn't want anyone to think I wasn't interested in their thoughts or their brews...because I most certainly am!

Try typing this in after Ral Zarek in your decklist: A=693. Trust me, it is pretty cool.

That was supposed to be *A=693*

Have you considered The Chain Veil? I have a similar list that utilizes it. Could be it just sucks. Let me know what you think!

RUG Chainwalkers [Modern Temur Superfiends]

Since you're running Temur colors and Doubling Season, you could also run Sage of Hours with Forced Adaptation/Dragon Blood and take a few consecutive turns.

Personally, I'd try a Sultai version of this and use Corpsejack Menace along with Doubling Season, increasing the chances of getting a counter multiplier.
