I have recently found a LGS that hosts commander games on a regular basis and I'm looking to upgrade my Prossh deck before jumping in. I am unsure on what the meta will be like but I'm pretty sure the amount of removal in my deck needs to be upgraded and probably some tutors need to be added. I am also thinking about moving to creature based mana ramp instead of spells, so hopefully that will free up some slots. My budget for the upgrades is 100-150 dollars, any help is much appreciated.
