TGT - for the most part requires defensive help, or delving into a second brigade. In saying that, white/gold might work for you with gold's late game potency.
Royals - tend to be small but often lack punch (could be what you're looking for)
Priests - alone... COULD work (priests/prophets would take too many slots though). Probably utilize all the new'ish' banding with Z-Temple...
Judges seat - haven't tried it enough to offer a good opinion. Seems like it might rely too much on that fort though...
Genesis - I think this is your best bet. Has very good recursion, a late game character in Zebulun, and could even help your sitelock if you needed it to...
Prophets - straight up prophets might help protect from abom (an oft overlooked site killer) as well as being a somewhat small and decent offense.
Silver - with all the time you'll have you could utilize the powerful set-asides, IaH/Chamber, and Mike plus angel's sword... (could add the destroyer + ET + AoC combo)
