Hello looking for opinions on my build. I try to keep my decks under $50 so keep that in mind but I don't mind going up to $75 if it will make a significant difference in the gameplay. I am wondering if I need to swap out some of the mutate creatures for more creatures that mill from my library. I do not want to deck myself though. if you have any ideas let me know what card you would take out and what card you would replace it with. Thank you in advance.
