Well, if I were you, I would try to implement one combo in particular: Set aside King Lemuel with Gathering of Angels, bring him into battle and exchange a SA-less enhancement (Philosophy is nice if you can get it) from your hand with Peace Treaty from your discard pile, then band to Ethiopian Treasurer, get back the enhancement you just discarded, and play Peace Treaty to ignore whatever brigade your opponent is using. The cards you need for this are King Lemuel, Ethiopian Treasurer, Gathering of Angels, Peace Treaty, Philosophy (or another SA-less enhancement), and probably at least two royal female heroes (for King Lemuel's ability to work). The only other Purple cards I can think of that you must have are AoCP and Reach of Desperation. For silver, I would strongly suggest Cherubim, who can band to a purple hero. And if you have a large offense, Second Seal is a fine addition indeed. Also, if you are not using a NT defense, I would strongly suggest using either Book of Life or Might of Angels, as both Purple and Silver are relatively bad at getting rid of Demons (most of which are NT).
