This is the Kolento Priest of the Feast Karazhan Priest Deck he was playing on stream at high legend. Priest has been all the talk in the community of late for being too weak. The new card Priest of the Feast brings some stability to deck for sure, it’s a strong card and you can really leverage a lot of healing from it.
The key to winning with this deck is planning what you will be resurrecting with the card Resurrect depending on your opponent. A 2 mana resurrect is really powerful when performed on an Injured Blademaster or a Priest of the Feast and can give you a tempo swing. Along with the powerful board clears and healing in the deck you can outvalue a lot of opponents.
