I did quote the important part of the rule on the first page. But this is actually looking like the the old arguments in Magic regarding their Shroud rule. It's targeting without targeting/specifically saying it's targeting. But beyond the in game hindrances Imotekh causes to allies, fluff-wise, he's the Necron Overlord least likely to ally with anything.
