You already know / That this is a bandwagon / So guess who's joining. (How did I turn that into a haiku?)
Based SOLELY on Trained Art.
Really, there should be another tier cutting B and C but... I'd rather not.
It's really hard to correctly determine how much you like a card when you think cards look better in-game and to see the card in-game, you need to OWN the card. That means there is potential bias towards cards I own but... I think that only applies to S+ Tae and Yukina here and I'd put them up there anyway.
Point learned from this: I love cameo cards.
Make your own here. Obviously, this tier list is my opinion and I don't expect anyone to not have a point of disagreement with me.
Feel free to @ me about this enitre tierlist.
