There is always a lot of interest in the Priest decks Zetalot 
uses to achieve legend. This is the Zetalot Legend Priest Deck July 16 season 28 list.
This list seems to be the strongest right now for Priest. Having N’Zoth to bring back Sylvanas Windrunner and Shifting Shades represents a lot of value. Both in minion body’s, and some extra cards from the Shifting Shades.
It’s well-known that post-Old Gods Priest isn’t the strongest class. But this deck proves it can hang with the best when played well and tweaked to work with the META.
Give this list a go and see how you get on. It’s not the easiest to play if you’re not familiar with playing Priest, but you will get the hang of it.
