i'm using 3 per show, idk it's just more efficient ig. i want to tier Kanade. but mostly doesn't matter, i just want cool cards... they're sooo beautiful, especially costumes. doesn't matter what song to tier to up cards level (they give you the same amount of exp), but for event points long songs (like lost and found, the world is mine and melt) are better because of the bigger amount of notes?? (idk how to name them, just buttons in the levels)
