Are 'trick' spells viable?

I was thinking of combat spells, and forgot about remember Soul Drain. I don't think Evocation has any more, and the only other summons (besides Eater of the Dead) I can think of are Nether Gate and Vengeance of the Dead. The latter isn't really a summon spell, though.

Well, there is technically Nether Bolt. For the research-impaired. Such as undead Ermor. Both Soul Gate and Ashen Empire have good access to astral/death, but extremely slow research, and both have better schools to research than Evocation.
