Omega Shenron has a semi-farmable SA, thanks to the relatively common SR AGL Syn Shenron, who dokkan awakens into SSR/UR Omega Shenron. Just something to keep in mind, in case you want to save Elder Kais.

Trunks does require a bit of time, but his story event is the most recent one, which means that you'll have one more week after the end of the Hercule badges events... not many Top Tier units have a farmable SA, so it might be worth it, since it might take six months for the story event to come back. As a lazy person I can empathize, though, they shouldn't release these events all at once.
