old school with new stuff

Shepherd's Horn is a very good card and can make a lot of life. (probably more than you suppose if you don't test it)
some old combo with Worldbearer Behemoth and Mystic Ascendant or Dawnwalker and Xenan Initiation
You can win just with the body of your unite and a Striking Snake Formation but Talir, Who Sees Beyond + Kairos, Grand Champion will finish the game for sure.
you can choose to make Talir, Who Sees Beyond in your market but you will need to play 2 market card for the combo.
Warning, you can't play Kairos, Grand Champion if you don't have Talir, Who Sees Beyond on board.
If you can survive for have 9 power, the most way to win is play Talir, Who Sees Beyond and time etchings for choose Kairos, Grand Champion

if computer put a Permafrost on Tocas, Waystone Harvester you can twist at max
