I need sum input

I’m trying to create some art based off of the game but I don’t know what two magics should face off. I tried a random number generator but after around 20 times I couldn’t choose a pair so I just decided to go on here. Anyone have any ideas on which two base magics should brawl?

Magma and water

light and shadow.

to represent good and bad.

Or fire and water

or lightning and fire

or promethean fire and dark fire

or solar and lunar

or you get the point.
