Cosmic Trinity farming with without Yog-Sothoth

Cosmic Trinity with Yog has been all the rage but not everyone owns Yog. Luckily there’s a free Yog available to all players. Thanks padmuffinkins for bringing it up in comments and giving me the idea to look more closely at it.
I wish I could add LMyr as a farmable heart generator but it won’t work when the full board is lights.
What can we do with a farmable Radra team now that the 55s have hit?

Non-Row Gremory Teams? THEY EXIST?!?!

Should I buy Dark Athena and what cards should I run with her?
