Pythium's Magery

[Huzurdaddi]

When you want to deal damage you have two spells: Thunderstrike ( which is great ), and Falling Frost ( decent ) and that is about it.

Enslave mind is decent aginst SC's but not usually worth it when you are facing larger armies.

OTOH you can buff your army with quite a few spells: Anti-magic, Astral Healing ( which your theurges will cast by themselves, and quite often in some battles. Leading to some comical communicants ), Arrow Fend, Mass Flight, Doom, Will of the Fates, Fog Warriors.

And of course dont forget the suicidal F2 mage with crystal matrix casting phoenix power with multiple communicants attacking closest If its a F2 arch theurg you could cast flight second turn too(and feel free to add in a screen for protection while buffing)

[Manuk]

Enslave mind is useful almost always.
