smash tap is an official app game available in the japanese app store (unfortunately, no english version to be released as of yet) where you can play as different bnha characters and unlock special cards to play as! if you've ever heard of love live...I guess it's kind of like that? you can scout for different cards from boxes, getting three star cards, four stars, and the highest is five stars.
they have different events, such as the fantasy event and bean throwing event!! and then they released an oni set with kirishima and kaminari <3
for example; here's the oni kaminari card that was released ( I think it's five stars! ) matching with the oni kirishima card!
smash tap has some really cool card designs I suggest checking out, I know tumblr uploads a lot of them.
