#3. Stipulations in Matches
For those unfamiliar with the Broken Matt Hardy gimmick, you should be aware that one of the most successful parts of Impact Wrestling in 2016 and 2017 was the emergence of the Broken Matt Hardy character, and his personally financed and produced "Deletions". Events such as his Broken Brilliance, Delete or Decay and The Final Deletion presented some unique qualities that in WWE have not been used.
With Bray Wyatt, fans have seen the house of horrors match with Randy Orton, they have seen him take part in Hell in a Cell match and various cage matches that showed his willingness to cross the line and do as much harm to himself as to his opponents. Could we see something along the lines of a battle at the two different compounds, one belonging to each man? It certainly could engage fan interest throughout, though gimmick matches can be hit or miss. However, these two could have some rather unique stipulations or elements in their matches, ones that could be rather different from what fans of WWE have ever seen before.
