Guardian Force
Circles: Life, Summoning
Description: The wizard summons a powerful benevolent being on the battlefield, which shields his units from magical effects. Saving throws of all units go up by 2 and the guardian force tries to dispel the first spell cast on your army by an enemy.

This is a neat idea. However, I wonder if we should be able to see the “Guardian” on the battlefield. It needs something that really says it's a Summoning spell. We don't just want a Protection spell with a more flamboyant description.

What can we do to make it more “summoned creature” and less “magical protection”?
