For my playstyle in single player games, nothing beats a Wraith Lord. Incredibly durable due to their starting equipment, with the ability to cast Soul Vortex and then just wade through hundreds and hundreds of the chaff the AI loves to recruit so much, these guys are also immortal if things go awry.

With this in mind, your best bet is probably LA C'tis because you can get a D5 mage very easily, and search every province for death sites from turn 2. You need Conjuration to cast the spell and Alteration for the Soul Vortex.

I equip them with a Frost/Fire/Shadow Brand, Charcoal Shield, and a Pendant of Luck. Nothing more is necessary, you could probably get away with less.

This should give you a good starting point to say, "I like this" or "I don't like this" and maybe try something else. Blood and Death have the best end game summons, but often nations have their own spells typically called "National Summons". If you are looking for good national summons try the angels of Marignon.
