Praxis rebuild "combo"

Inspired by Maneiro, who I have seen running around with a similar deck.

General gameplan is to build up a bunch of fire influence, then play Rebuild with a bunch of draw effects after. Use Cuno, Chronomancer and Excavate / Turn Back Time from the market to re-use any rebuilds that are already in the void with destiny. Also, unless your hand is a real banger, just default to using Wrath of Caiphus immediately if you have a rebuild in the deck with revenge on, as that will often start the snowball to win you the game.

Not really true combo, but generally speaking if you get a couple rebuilds off and don't stall on card draw, then you will win the game by snowballing with Kairos, Grand Champion (sometimes you can kill outright with Pyrotech Explosion).

Suggestions welcome. The deck would improve against aggro significantly if you put Chronostorm in the main deck instead of market, though I'm not sure what to take out. Maybe Cuno? Contract is kinda expensive and the unit isn't that big.
