Not 100% sure. Here are some cards that might help get you started:
King Amon (Di) gets a card back from discard
Wickedness of the Tenants (Di) is a good interrupt/battle winner that is cob on OT ECs
Haman is Persian and seems good with Prophets being meta. Haman’s Boasting works as an interrupt/D3/Play when used by Haman. Otherwise it is stil an interrupt/D3.
Provoked (CoW) is situational, but can be a decent draw. Potential for battle winner depending on what opponent is playing.
King Saul (CoW) has a good D1 and can band to The Amalekites slave (which should be in most brown or gold defenses), and The A Slave can exchange with another human EC in deck.
Broken Covenant (CoW) seems forgotten about by most now, but can get you a draw and gets rid of opponent’s You Will Remain.
Medium in Endor can be quite pesky. I learned that for sure at the T2 only...
Withered plant returns itself to hand after battle if used against a green prophet.
Also, depending on what you are using on offense, you may be able recur dual alignment enhancements that have brown on them easier with your offense. Specifically white is pretty good at that, but there are other opportunities too.
Hopefully that helps somewhat.
