The one argument for a downside on being the ringbearer is that is puts a target on that creature’s back. Maybe not a huge downside but flavorfully that does check out imo. I like that the ring tracker actually rips off to physically place on that creature. I think tracking it will be pretty easy. I do agree that we are getting too many components like emblem type effects that exist in a space that is un-interactable.
Pet card: Serra Avatar. Showing my age a bit, I remember reading a spoiler for it IN A MAGAZINE. Scry I think. It blew my mind. Still a cool card, but not the powerhouse I envisioned.
