Wrenn and Six put in a lot of work picking off their earlier creatures, while Ephemerate makes it difficult for those decks to remove your threats
The most popular options before were partners Ravos, Soultender & Tymna the Weaver, Athreos, God of Passage, and Ayli, Eternal Pilgrim, all supporting both Cleric themes of Lifegain and Sacrifice
And you arent even playing Zendikar Rising
While Mirri, Weatherlight Duelist, unfortunately, wont protect you from board clearing removal spells, her ability that prevents more than one creature from attacking you while shes tapped isnt to be dismissed
