Same here. As a concept it seemed nice, you get Yoshi's figure and you use that in different games across the board to get different things. It turned out every game will need its special iteration of Yoshi's amiibo so what I'm doing in reality is buying expensive DLC for every single game. The cards will somehow mitigate other bad side effects, like scalpers and storing a silly amount of figures at home, but the expensive DLC bit for every single game remains true.
That actually isn't true.
