The combo is to play Talir and then last chance or play a merchant. This will let you draw Kairos with Destiny and any units that Kairos draws will also have destiny.
The deck can also play a decent midrange game with Sites and Azindel
Compared to Vodakhan / Grinva lists, this one gets to play sites, spells, and relics.
I'm also still experimenting with market options.
If you draw Kairos while you have Talir in play, it will have destiny, play for free, and any units that Kairos draws will also play for free.
