Scribe.
Scribe only recurs enhancements, not ECs.
There are a few ways to recur ECs:
Mist
Rebellious Spirit
Worse than the First
Evil Sacrifices
Marketplace
Noah
Eternal Covenant/Shrine to Artemis (only works for DACs)
Doctrine Like Leaven
Anything that recurs an OT Gold GE (only works for Fire Foxes)
I'm saying scribe could get back raising the babylonians, then if he dies in battle, play it, get him back, and perpetual EC recursion.
Honestly, I actually forgot about scribe because I don't play him much anymore with all the new awesome gray cards out there. But he would be so awesome with RTB's!!!! Stellar! Too keep it from being OP'ing my opponent could use Confusion to name Raising the Babylonians instead of SoG!
