Since everything has a Zephrys in their decks these days I thought, why not priest? All I can say is it beat Murloc Paladin, it beat a poorly played Murloc Shaman and is a for fun/meme deck. I don't know if my list is optimal, good or meta-countering. But if you like semi-control, stalling, clutching on some Zephys RNG or praying for good card RNG to carry you to fatigue so that Elysiana can extend the game then by all means try the deck. I had not seen a Zephyrs/Highlander standard Priest so try mine if you like, modify it, let me know if something else works better or not. Whatever you do try to have fun!
