I'm loving this Momir's madness event. I'm going near infinite and have collected 10+ new mythics so far. I leaned my lesson with demonlord bezenlok and at 6 mana I pull a 5 cost if I have anywhere near an advantage. I I won several games were I was completely dead the neat turn but my opponent pulled a demonlord bezenlok un necessarily. So far my general strat is to pass until I have 3 mana so that I can maintain a high casting cost meta game. I also prefer 7 cost vs 8 costs and try for the 9 cost deal 3 damage card so prefer dropping mountains to blast stuff down
I'm sure you've had some great rng and done well, but it's not possible to go infinite in momir's.
