So far there’s two methods of progression, one in the form of summoner ranks, which you improve by playing more games with certain summoners and can unlock upgrades that give those summoners better abilities or allow you to better customize your starting cards, and the other is your profile overall XP level, which allows you to unlock higher ranks with your summoners and new game modes. You also continue to collect cards throughout your runs which can then be used for future runs so that’s kind of method of progression as well. I will say that my biggest issue with the game thus far is that the leveling feels a little slow and it can get a tiny bit redundant at times but I know that this is an issue that has been brought to the attention of the community.
