The cards do still work. The tickets that were originally on it would have expired but it is still on your account as active and will work unless you expressly turn it off in your account.

A card is exactly the same as a magic band. It is just another identifier to your account. The tickets are not on the card they are in your MDE account. Anything that can identify that MDE account will work. If it is active on MDE it will work.
