Hmm, maybe I'm misunderstanding you, but a revocation certificate is
not some kind of root-key and also it (probably) isn't stored on a
smartcard, no need to do that. So, just one card.

The revocation certificate is created using your own, private key (the
same one that is / will be stored on your card). It definitely needs
to be protected and safely stored, because everybody who's got it can
revoke your public key.
But in no case a central issuer is required.
