Playing around with the breeding calculator, it seems there are a couple decent combinations for getting Mercury.

Using Lunar Ram or Athletic + Diamond, you would eliminate common and super rare results from the mix. Only 4 results possible: another athletic or lunar ram (both rare), crusader or mercury (both ultra rare). I'd still expect a few fails, but the chances seem well above average.

The other good option would be Sorcerer or Illusion + Diamond. The only common result is coral for 10 hours, which is better than 12 hour water dragon fails. Plus you also have possibility of getting 4 different diamond hybrids: Mercury, Anubis, Dark Angel or Black Diamond! These are some of the best diamond types in the game!
