UNIT - Creature Balance + Visual Changes

Are unicorns a balanced creature? Personally, I always preferred taking the resistance aura. After all, resurrection for two is nice, but in battle, they primarily use general combat spells. I suggest slightly buffing the light unicorns.

Resurrection for two is actually ambiguous, as it reduces the total health of the unit. Regeneration for two is powerful. Antimagic for two is powerful. Honestly, I never took combat unicorns after the light ones appeared; their ability looks so weak. Perhaps they make sense if the guild doesn't have regeneration and the hero is developed in some kind of chaos instead of light.
