A card that worked sort of like Borne Far Away for the discard pile might work, something like this:
A Light In His Eyes ![Gondor [Gondor]](https://lotrtcgdb.com/forums/Smileys/classic/gondor.png)
Exchange an unbound companion in play with a companion with the same title in your discard pile. Transfer all wounds and cards borne by the companion being discarded to the companion entering play.
"Frodo turned and saw Strider, and yet not Strider; for the weatherworn Ranger was no longer there. In the stern sat Aragorn son of Arathorn, proud and erect...."
So basically, you stack your deck with, say, four different versions of Aragorn, probably starting with, I don't know, Strider?
Get a look at the type of deck your opponent is playing, then use a card like the one recommended above to take a different Aragorn from your discard pile (assuming you've discarded him somewhere throughout the game) and basically swap the two. No breaking of dead pile rules or "out of play" manipulation or anything.
Not the greatest of ideas, but I can see where it would definitely have its uses.
What if the cards played on the old companion can't be played on the new one, e.g., playing several

cards on Aragorn,
DoR then swapping him for another Aragorn? Or has there already been some ruling on this (e.g., if
Armor of the White City is discarded from a companion bearing
Gondorian Steed)? Also, would "to play" requirements need to be met, e.g., could you swap Denethor,
OtEoM for Denethor,
LoMT if you didn't have any other

Men? Also, would Denethor be able to spot himself (along with one other
![Gondor [Gondor]](https://lotrtcgdb.com/forums/Smileys/classic/gondor.png)
Man) for the requirement (since he's technically already in play)?
I suppose such a card would also need to be checked carefully to ensure that it didn't allow any broken combos, since many cards were designed with the assumption that they couldn't be used with other cards.
