This is a deck that I’ve had a lot of fun playing with. I would say that it’s not a top deck. That being said, from my own experience, this deck has a positive winrate at least in the gold tiers. I would say I’m around a 70% winrate.
The goal of the deck is to stall out the opponent with all of the deadly units until you draw Katra which buffs all of your units for an alpha strike. Try to save your removal for the creatures that you would have trouble dealing with using creatures.
The deck is very good against midrange, and has done quite well against Aggro due to all of the lifegain. The fact that is has chalice makes it capable of winning against control as well.
I hope anyone who tries this deck has a lot of fun with it, and has good luck!
