I myself as an example, I have no really expensive cards, but I spent around $200 once, and my inventory now has the 6*s worth a total of about 1100~1200TE.
Creamy, Borage, Nina, Ombre, Isis, CharlesX2. Morticia.
and 90TE+ a few pots in my inventory.
Oh, and 5*s like Reamy, Alraune, Agatasche(m), Antiope(m), Sarah, Soldado, Kyo.
I don't see any reason in why people who pay more cannot have multiple super expensive cards that are way more than what they have paid.
