I'll trade you my Level 3 Clara for your Level 5 Emeth.. let me know.
That's more fair than the trades you are looking for. The only remotely fair trades I can see are Amiral Py and Emeth. The rest of those cards are rather pathetic compared to the Pussycats you want.
You are asking for a good portion of the best Pussycats in the game, and offering mediocre Juntas for them (the only real exception is Emeth). How can you possibly figure that to be fair?
