Unless I'm forgetting something, Cure Echo can't use Prism Cards remember?

Though I suppose you could rationalize it as she got an upgrade that allows her to use copies created by the Prism Flower (as at least some of the Cures would still have their powers in this season), in which case she would use Cure Black, Cure Moonlight, Cure Etoile, Cure Horn, and Cure Scarlet, as well as a few post-Prism Hearts teams.
