This will be the last game in our local league, game 14. I am trying to pack as much

into it as I can, as I am one game away from 3rd place, and there's no prize for 4th. I have to play
IG primary, but other than that, just about anything is open. My opponent is a Wraith heavy Eldar army, and I expect 3+ Spiritseers, tossing Protect on Wraithguard and/or Wraithblades, a couple Wraithknights and/or 'Lords, and a bunch of Wave Serpents. What do you think? Will this list handle what I need it to? What could/should I take instead?
