I think the most efficient way (least number of combinations) is to use the following combination: Sea (Tropic/Blue hybrid) + Royal (pure Royal type, i.e. Jester/Castle/Royal).

This combination only has one 24 hr result, which would be the Islander. So if you get that time on your nest you know you've got it! But being Ultra Rare that is a long shot though. I have a week's break from Bingo so will give it a good go.
