(1. Virtually limitless power should not be pulled out of nowhere. Parlys got his power by capturing the princesses of Equestria, and that earned him a swift retaliation. Folderol has his power because of years spent draining magic from the ocean, and even that backfired to some extent. It needs to have some logic behind it. "I have no idea" won't cut it. You need to have some idea of what you're doing and communicate that idea.)

(2. Harnessing enough power to destroy a city and using that power against one target in a city... is more likely to destroy the city than the target. There's little reason to that.)
