So after i got quiet bored with my combo decks since all got wrecked by Qlock i tried your deck. I started at D5 and it took me 82 games to get to legend. I was quiet unlucky i guess since i spend about 30-40 games only on D1. Lost 6 times the boss fight. I got 5 times fucking Celestial Alignment druid for boss fight. I hate that deck so much. He does nothing for 5 turns and then play his whole deck in one turn to win Zzzzz.
The only change i made was that i took out the 2 Bloodsail Cultist and replaced it with Sharkfin Fan. If it helped or not...who knows. I just felt that the Bloodsail Cultist can be very slow considering only 1 weapon. And sometimes i got stuck with to many 3-4 mana cards in hand.
I hope there will be some changes in wild really. I still miss legend with rogue & DK. But atm its hard to bring those through the top ranks:(
