Nice tcg.... So far. Huge flaws for free players though. Once tutorial is done and ur about lvl 6 you hit massive walls on new cards. Within 1 hour of playing im now forced to stop play for 3 hours cause im opening a pack and side slots ate maxed (4) to open later... You can use resources to open but its hard to come by least for me. Only way to speed up seems like money. I could continue to play but im familar with this model the more i rank the longer the wait. Hopefully im wrong cause its fun
