It worked for me. Hope it works for you 🙂

Great to hear that m8! Hope you got Arthas by now 😀

Nice to hear that m8 glad the deck could help you 🙂

Sorry to hear that m8. You were rly unlucky with the blizzard then! The cards he plays 100 % is the turn 1 spell that gets your HP to 1 and turn 7 Frostmourne.

Try this deck;

It worked very well for me. LK was down after less than 8 tries. No need for all those fancy legendaries and the only legendary in this deck can be replaced by any other viable card that goes with this deck.

Hello Evident. I am sorry that you have this guy “Omnikoro” doubting you and that he thinks (although I think he’s a troll) that all the comments here are bots. I have tried this deck and i beat the LK after around 10 attempts. This is a rly nice deck and I managed to kill LK in round 6 on my last try. I also managed to win against him with a similiar deck with mage. Before I tried murlock paladin. I will try post the deck on this site. Thx m8

When you said it was OP i didn’t know it was THAT OP lol. Nice deck!

I made this mage deck since i needed to complete some quests but I generally dislike playing mage, unless its a Tavern Brawl. Works well against most decks but has hard time against hunters.
