Reality Fracture has Commander players digging through Echoverse cards, echoed legends, and strange new interactions that could reshape plenty of deck lists. With everyone testing ideas before committing to expensive upgrades, Mythicblackcore with mtg proxies gives players room to put those fresh concepts through actual games first. It is especially useful when a new commander looks ridiculous on paper but still needs pod testing. If your group is already brewing around Reality Fracture, this is worth checking before locking in your next list.
