Today’s commander card does just that as many times as you may want.
Mageta the Lion is a legendary creature from the prophecy set. Prophecy was expensive in the sense that every other card is asking you to discard and sacrifice creatures or lands, but two cards and four mana is really not asking much for a reusable wrath of god. Mageta the Lion destroys all creatures except itself, and those creatures cannot be regenerated. Mageta is not all that impressive as an attacker, so I would not go running him into battle, but he does present a hefty threat to your fellow players so keeping him available for a second wrath of god may be difficult.
