For those of you who didn't catch it in my last article, a Solitaire is an Eldar Autarch that has purchased the Mantle of the Laughing God, a Jetbike, and a Laser Lance. That means that (as long as he moved or is touching cover) he has a 2+ cover save that he gets to reroll, he has 5 WS6 S6 AP3 attacks on the charge, and he has Hit and Run. Of course, he gets all the goodness for that comes with having a jetbike as well. He does, however, lose his IC status, and he is stuck with terrible S3 AP- attacks outside of the charge. (I like him with the Banshee mask as well, for reasons I'll go into later.)
That adds up to a unit that has to be used as a scalpel, in support of a larger force. While he's not going to break armies on his own, he's an invaluable asset not only to many Eldar forces, but as an ally.

9x Jetbikes, (3x Cannon)
That's an nice 506 points that will slot well into just about ANY build- it's so fast, and brings such nice benefits and firepower, that it will be a boon to just about any list. (If the Jetbike Squads are only 6xbike2xcannon, it's 384 points, 3x1x is 262, and still excellent. Of course, you can also save 5 points, if you don't like the Banshee Mask like I do.)
You can use this not only to harass the enemy, but to bring some extremely fast scoring and contesting units. It is frankly a little crazy good. It's also a solid foundation in which you can season to taste with other ally units: a Fire Prism, perhaps, or some Warp Spiders. Maybe go all-out on the bikes and bring some Shining Spears. Keep that speed mojo going.
