Super power for a day/one time use

[Bourne]

The ability to remove 6.6 billion people from our planet, and completely erase all of the damage we have caused it (cities, pollution, Bryan Adams).

I would wish for the ability to conjure up a magical talisman that would exist permanently and it would give me whatever powers I wanted permanently. So I would just conjure up a couple (in case I lost one) on the day I had the original power, and the I would have these talismans for the rest of my existence and they could grant me whatever power I wanted - permanently. I rule.
