R-G-B

I do not own the Mordor cycle so I didn't use any cards from it. Followed is the only card from the Haradrim cycle that I proxied (I don't own this cycle either), but you could swap it for something else, e.g. Feint or some other trap.

I thoroughly enjoy playing these decks on their own, but they should work very well together as well. There are no conflicts of unique cards, you and can build these decks from a single collection.
