>>55831642A quick look on the wiki tells me that Rollout effectively caps in base power at 960 (last hit + Defense Curl). I can't think anything off the top of my head that beats that. Stored Power only gets to 860. Ice Ball ties with it of course, but I don't think any Ice types can out damage it. There might be some ability boosts I'm overlooking, but I don't think any are better than skill swapping Pure Power in this case.
