Even without GoH or the Chalice, neither of which can be guaranteed in any serious MP game, Tartarians are feasible. Enough come without Feeblemind to be useful. Machaka has good Death, though they will need to bootstrap up to Tartarian summoning level and they've got good enough Nature for GoR.
If they can get, from Indy mages, trading, or a pretender a Moonvine Bracelet, they could cast GoH, but keeping it up is trickier.
That, plus possible elemental (Fire/Earth) royalty, is an endgame.

Isn't everyone without national SCs in roughly the same situation? Except many have more trouble getting into Death and Nature in the first place.
With clams gone, Wish is much less common and usually relies on a pretender anyway. Racing for the Blood uniques is the other real choice.
