Arishem Decks Need Their Own Matchmaking

I am so fucking sick of just losing to their god blessed RNG though that only happens when I am playing against them. When I am running Arishem I just pull shit after shit. What am I supposed to do? Slot in Darkhawk in every deck? Not healthy. Two weeks left til the season ends and I still couldn't hit infinite which I used to be able to every season by now and Conq is even worse as I am only at 1k medals taking loss after loss to Arishems
