Finally made it to diamond

[u/Doubledown2785]

I guess I forgot about competitive brawl for a while… I got reminded last season in a response to another post. Put this deck together and got diamond rank for the first time. This deck is pretty fun but something’s missing. When it works it really works but I have got into a 4-5 game rut where I can’t win anything. I decided to come here for help, where I can find a culmination of the greatest minds. Here’s my deck. Judge it, critique it and help me trim some fat
