If so, could I put orikan with an eternity cryptek who has a chronometron to let orikan re roll his empowered special rule each turn?
How is deep striking on the enemy turn beneficial? (like how deathmarks can)
The last question is still up for debate, but most people think it will be answered with 6th edition.
With units that cannot shoot (Flayed Ones) it has the advantage of not having to reserve role for that unit, without any real disadvantages (they were going to shoot at you first anyway).
Outside of that though, the jury is still out.
