I want to make a new mono deck and I'm trying to decide on Uppers or Montana. What holds me up is mainly the bonus. A -10 min.3 is great but a -12 min 8 is great too. What lacks in Montana is amazing stand out cheap 2* but there are needs in Uppers too. I focus on 2* and 5* because those are usually what makes the best deck when both of those are great.
