There isn't a combo which is better than another. Although as it states on the Moon and Sun pages Bluefire/Crystal is the most common successful Combo. Myself has had two Rares with this combo. But this also gives you higher incubation periods such as a 24hr for the Crystal.

There is a Combo Brass/Cactus where it shows the less incubation times for failing an attempt which is 5hrs being the highest. So the advantage to this is, you're able to try more attempts to successfully get a rare unlike the above combo.

But that is just purely for your information as it hasnt been proven to be which combo is more successful.

Good luck though.
