Maybe even have powerful spells have one of those little drawn scenes like when you get married. I personally overshat myself when I got married in the 2b and saw that drawing come to life!
This is what will make Elemental fun for years to come. I still like watching the cut scenes from gal civ2 just casue they are awesome.
Fireball or bolt: Massive fire flying out of the sovereign's hands
Change land spells: Wastes becoming gardens and animals returning
Teleport Spell: Just basically give us a more detailed drawing of its icon
Not for every spell mind you. Make it random or just the really cool ones.
