Depends. Do you want to keep the magics? Do you want to try somehting new? Would any bless effects boost your mages enough to consider that? Extra reinvigoration from Earth 4 might be, but you wouldn't be able to use that for anything else... And some people would warn you about Magic Duel: one lucky Shaman can kill your pretender... Luckily, you have more astral mages than most other nations, so that shouldn't be that big danger.
If you want a site-searcher, remember that one Arch Theurg has air-2 water-1 astral-3, so you shouldn't take those magics if you are not going higher than what any AT can do... Instead, buy one AT to go with your pretender. Or behind him, as you see what provinces you have already searched. With this, you could drop out astral, maybe air and/or water too, and go for better scales.
Oh, you had a Great Enchantress... Well, if you don't need astral gems that much you might want to try a druid. Bog beasts might be good to go with your hydras and vinemen, although you would have to be lucky to get good mages...
Or maybe you would like to try Serpent cult, for greatest success you should have some kind of a bless effect though.
Generally, do anything you like.
Maybe you can pick one of these things and go with it. Maybe you would like to try other race for a change. Or maybe you should try going for a harder game. Damn, I started it againg...
EDIT: I think you got it now. Two summer swords and one commander = supply one sword would give you.
two swords and two commanders, both holding one = supplies of both swords
also edited some grammar
