Hearthpwn

I need some help with this deck. I’ve been hardstuck at diamond 5 for like the past 3 seasons. What should I replace? What legends would work well with this? Do I have too many tech cards?

This deck has a positive winrate against big priest, secret mage, and most aggro decks but I only win if I draw the right cards. If the big priest can get an early blood of g’huun and I can’t transform it I pretty much lose.

This deck struggles against other highlander decks, mill rogue, kingsbane rogue, and odd/bomb warriors.

This deck is fun tho
