MTG is a great game. MTG: Arena however is a trainwreck. You dont have to be a genius to understand that the shuffling algorithm has nothing to do with rng. Mana flood/drought are a huge problem that will frequently decide whether or not you win. I dont know if it has anything to do with a pay wall, or just bad design, but I definately would not recommend wasting time with this game unless you either have alot of money to waste to find out, or you just hate yourself.
