#3 Many exciting matches for the Rated-R Superstar

If you have been following either Becky Lynch or Edge's Twitter handles, you would know the intense rivalry they were in a couple of months ago. The Twitter battle got so heated that even the respective partners of the two, Seth Rollins and Beth Phoenix, got involved in it.
With him already having been in a feud with the two top champions on RAW, the storyline for his comeback should not be a tough one to write. A match between Seth Rollins and Edge is one of the dream matches for many, and maybe we can get some glimpses of the same in this.

If not, then Edge still has many dream opponents in the current roster. Someone like AJ Styles could give him a great final match to end his career with. Another interesting possibility would be a match against Roman Reigns - Spear vs Spear!
#2 Can be a one-off appearance with a safe opponent

In the recent podcast of Edge, he mentioned how his neck is in a better state than what it was 5 years ago. In his own words -
I could pull off one. I’m not saying I could pull off a year’s worth.
Well if that is the case, then a one-off appearance can never be counted out. Of course, no one is expecting him to have a long run. While it can be argued that Edge might not be able to compete with that intensity that he was so famous for, a single return match against a safer opponent could be in the plans.
Who could that safer opponent be? AJ Styles? Or maybe Daniel Bryan? What do you think?
In any case, the health of the superstar comes first and WWE medical team would be very careful before giving him the green light.
