There is an app version that is not marvel or any licensed property themed if you just wanna try out the game mechanics. Also it’s really clever how they created a simple way for the game to play back against you as the villain
This is easily my favorite deck building game, as well as my girlfriend’s. I literally have every expansion (Even though the annihilation expansion was hella hard to find)
There’s also a great app called Assemble that can randomize your deck for your choice in difficulty. Definitely a challenging game, and definitely can get super hard (especially some of the expansion masterminds). We’ve had the game beat us miultiple times!
