I think this is an interesting idea to run on. CAP 6 will never be able to compete with the likes of Moxiemence etc if it's vying for a late sweeper role. CAP 6 needs to be able to take out what an average offensive OU Pokemon can't at +2. I'm not saying we should decide on Explosion jut yet but it could be one way to distinguish CAP 6. No matter what route we take, we have to be prepared not just for revenge killers, but Pokemon with Sturdy or phazing moves. If we've ruled out late game due to competition (and I think we have) we need to focus on how CAP 6 can function well mid game once cores have been softened and proper team support is in play. Wallbreaking should be a focus.
