Hah! A ray of sunshine in my cloudy morning!
Attempt #7 -- Mercury & NightElf produced a 24-hour breed. Figuring it must be the green Arabian princess with the diamond-studded veil, I sped it up when a nest became available 2 hours later. If I get nothing else, I will have invested 122 gold for Black Diamond. Not too shabby.
But now my 8th attempt (same pair) is doing a 40-hour dance. OMG! It has to be Anubis!
Yeah, I'm wearing a ship-eating grin right about now.
I don't care whether it's temple mojo or dumb luck; I'm happy. Now if I can bag Dark Angel, Unicorn & Helios, I'll be ecstatic!
