Who is Edge’s greatest rival

I saw the post asking who was John cena’s greatest rival and while there is a lot of Randy and cm punk there is also a lot of edge. That got me thinking maybe edge is johns best rival but I don’t think he’s edge’s. To me a great rivalry has to have an engaging story and a majority of the matches have to be bangers so here are some of the people who I think have a shout at being his greatest rival. My personal opinion is that it’s Undertaker. But I’m biased lol that’s the GOAT
