(Game) Create your own gimmick match that would end a feud

[Splaya]

The WWE tends to use the Hell in a Cell to end a MAJOR feud.

So what would you guys call your gimmick match and what would be the rules.

One of mine:

The End of days match. Match is a 30 minute iron man match that is non sanctioned. After the 30 mins is up, the only way you can win the match is to use your opponent's finisher and then yours in succession. Ex. Randy Orton vs Jeff Hardy. Jeff Hardy would have to do the RKO and then the Swanton bomb to win the match.
