It seems like most people are focused on ramping with Praxis to get out Kairos, but there is a better approach. Although, this is largely because this actually an Icaria Gold deck that has some extra ramping built in for a Kairos win con as opposed to the old Martyr's Chains. Anyway, it seems like the meta is shifting away from these decks already, but this is something different that seems to do ok against the new Ixtun Unitless Control.
