I played Brawliseum with Ontes control shaman. I know it´s stupid copy-paste, but man, haven´t played a deck that is so fun like this in a long time in standard.  So my point is, what did I do wrong in this game? I even managed to pull his Seaforium Bomber with Hecklebot destroyed both of his weapons immedeatly,  I just can´t believe how stupidly oppressive is that new boom warrior. And I´m a core warrior player and I wanted a warrior to be again tier 1, but this way it´s just meh... RNG fiesta again. The only thing that comes in my mind is that Dr. Boom (hero card) is super strong giving mech minions Rush, while new strong mechs are printed and none of them rotated out. So what are your thoughts on that game? What play was the gamebreaker? Thanks for your answers.
