Cloudstone Curio will let you return a land to your hand and can be useful for recasting creatures either for their ETB triggers or just to get more Karametra triggers. It also helps if you're running a lot of enchantress effects.
Authority of the Consuls, Fumigate, True Conviction, and Resolute Archangel are the ones I switch between as I try out different builds. True Conviction also helps with devotion. Also depending on how big your creatures are Shamanic Revalation can be a decent heal spell while mainly helping you draw a lot of cards.
On a different note, Renegade Rallier + Saffi Eriksdotter/Angelic Renewal can infinitely loop with a sac outlet.
