Pick a god and pray. They won't be able to help you anyway.
The only parts I actually paid for were the horns and the MH, and the gloves you can get in 2 days of PvP'ing, so it's not hard to get.
As the weapon really is just the one I use, it should look good on most casters, especially on BLM.
As for other races, if you're going Au ra, Miqo'te or Viera, I didn't really like how the horns look with the extra ears and horns, so I'd suggest the Succubus Horns.
