This is a deck build around Kairos, Grand Champion and Xulta Arcanum.
The deck uses all kind of ramp and cards like Ramba, Arena Showman to make use of the high amounts of power this deck can generate. I've played/tested it a few times and so far its been really strong. Feel free to try this brew and give me some feedback in what I should change in either the deck or the market.

How are you finding xulta arcanum? Never looked amazing to me but it's in many new top decks. Sure the spells are alright but high cost nonetheless and a mediocre unit at The end.
It is because of Xulta arcanum I wanted to try this list,(I am just a huge fan of Kairos). This deck really ramps pretty fast and on occasion Ramba can make it cheaper which has happened quite a few times. Once the Arcanum is out the door to Kairos is wide open. Brenn is indeed not the best but together with Kairos it ends the game pretty quickly since you get even more power to work with.
