Using the free daily pulls and extra pulls on my end, I got Solomon early.
Here's the roll call so far:
Lucifer 0x, Mammon 0x, Levi 0x, Satan 2x, Asmo 1x, Beel 1x, Belphie 1x, Diavolo 0x, Barb 1x, Luke 2x, Simeon 2x, Solomon 1x

I'm broke on Nightbringer now, and had to use my saved exchange tickets from gacha 1 to use the pity system asap.
so now that I used exchange tickets from both gachas, I'd only have one enough pity for one single UR.
And out of the cards I haven't gotten, I think I'll go for the Mammon UR with the 1,000 tickets. The priority order is Mammon, then Diavolo, then Levi (I have plenty of Lucifer cards, and I don't have a Pride sin Levi UR yet).
My plan is set. And to close things off well, Solomon's card turned out to be a good concluding story if I want to take a hiatus after this event. Right on, Sol.
