The best offense to combo with I am Holy is assuredly Isaiah. He can instantly recur whatever card you discarded with I am Holy, CBN-style, and there are plenty of useful Isaiah cards to discard. ET is good too, but he is negatable, and you have to play with a no-SA enhancement like Philosophy, which is sometimes good, but not always.
With the recent ruling that Covenants and Curses are now Artifacts AND Enhancements while in hand or deck, Covenant Keepers could search for CWD.
Balaam is awesome. Not only is he a member of one of the best defensive themes in the game there is (Magicians) but he has an awesome ability. Manasseh+Balaam is a soft FBTNB chain that can hold off a lot of attacks. Also, his recursion of RBD, CoM, or CwD can be really helpful due to their high toughness and good abilities.
