I have noticed that the opening hand barely shuffles, I end up drawing the almost the same cards every single time with high mana costs like the 10 mana for Ulamog, The Ceaseless Hunger, and doing mulligan barely helps. Is there a way to escalate this because it's annoying and especially when playing brawl with 25 lives I'm forced to do decks with creatures with low mana costs and I want to play other stuff, but I'm very limited by the game itself.
