I missed out on the Epona last time around, but if it's off the table the Hephaestus, Mars, Morrigu, Oro, or Shamash would also be nice. As would the Donar or Anhur. Likewise the Urbanmech IIC or Ursus. If any of these have won recently, I'm sorry; I didn't pay a whole lot of attention to the Special Returns until recently.
