I've reached the point where I can allow my military access to Dark Archons, albeit at the cost of access to High Templar (I think). Now, High Templar are great units, but if I can turn the attacking Hybrid against my enemies, that could potentially open up the door for a huge amount of fun.
Is turnabout fair play? May I convince the Hybrid to destroy Amon's forces, much as he turned my Protoss against me?
If Mind Control doesn't work, does the secondary Confusion ability?
