Oh god, I want what the guy above me said. Mind Blast! I know sooooo many people I just want to blow their minds out(literally)
Mage Portal
Scuba Dive down about 10 meters in the open seas, open a portal to a city, Enjoy the chaos.
I would pick chain lighting so i can go "UUUNNLIMITED POOWAAAAH!!"
Portals, really. Portals is the best business you can find if you could pick just one power. You can travel around the world easily, and if you might need some cash, there's a solution for that. You travel to an airport and find people, then you ask where they wish to go on vacation and take there money - waving goodbye to them as the get scent through your portal to their destination.
Though, would want it to be without a cast time, so you can use them aggressively/Defensive.
FOMO: "Fear Of Missing Out", also commonly known as people with a mental issue of managing time and activities, many expecting others to fit into their schedule so they don't miss out on things to come. If FOMO becomes a problem for you, do seek help, it can be a very unhealthy lifestyle..
Remove Corruption and I would use it on America.

Everyone seem to prefer stealth. Just to be different ill pick Prowl!
Death Coil, cause a blast of shadowy death magic, is pretty sweet. Like a force blast but with icky feelings
Living Bomb
Heroic Leap, so I can jump around like a badass

For cool factor, probably flight form, though stealth would be a close second. Though, I suppose if I had 'cure disease' I could be a multi-trillionaire and help people in the process.
Mage portals... obviously.
