With the release of Heart of the Elders--and specifically the card Live and Learn--Oops!'s stock has definitely gone up. I'd seriously consider running this in a combat-oriented survivor deck over Overpower in a multiplayer setting now if I had to choose between the two. It's still a situational card, but pairing this with Live and Learn on a failed attack lets you damage another enemy at your location, then follow up immediately with a second, action-free attempt with a higher odds of success on your original target. This means you're potentially getting two damage-dealing attacks for one action. That's a serious tempo boost right there. And unlike previously suggested strategies using this card, with Live and Learn you can afford to take a swing at the bigger baddie knowing you're gonna get a second shot at it with a better chance of success if you fail.
Is this kind of combo going to line up every time? No, probably not. But it's a juicy enough proposition to warrant serious thought about running this card if you're building an investigator who'll be looking to knock some heads together.
