General Mulligans
To win you should have brawl turn 8 Destoryer/Golem turn 9 and then another golem/destroyer+frothing berserker turn 10. Although you can win without all these cards, you should just restart if you don't have them.
Video to show how to beat him with this deck. You might want to add another Wrapped Golem if you have it/enough dust to make it.
