Eater of the Dead

Still, such things are pretty rare (particularly for a specific spell) and are unlikely to have the same impact on a game as being able to spend astrals on eater of the dead vs. if you had no other astral summons.

Ether Gate is 90 gems, but it's easier to cast (conjuration_6 instead of conjuration_8) and you recieve some very powerful magic units and a powerful commander with magic paths.
I will gladly send one of my Ether Gate armies(90_gems) against two of your eater of the deads(100_gems).
