Cheap Teron Gorefiend Galakrond Priest Deck for Trial by Felfire Challenge

With this slow Priest deck, you should pace yourself with using your Vengeful Spirit cards, ideally only using them when there are 2 or 3 Shadowy Constructs on the board to help you safely reach the late game. Once you reach the late game, you should try to stick any minion onto the board and pair it with powerful spells like Psyche Split and Grave Rune and using Sandhoof Waterbearer and Apotheosis to regain any Health you lost in the early game. Once you have secured your position on the board, you should comfortably be able to kill off any further Shadowy Constructs with your minions as you grind down the boss.
