I remember something about new fees and not being able to use non-Amex cards. Haven't been back to Serve since.
I don't know about any new fees, but yes, you can only use Amex cards. However, that includes third-party Amexes like the Fidelity Amex. Amex-issued cards don't earn rewards on Serve loads.
