WWE2K19-UNIVERSE MODE TRICK AND TIPS

My first time doing this sorry if i was too fast.
But basically the trick is simple to edit rivalries is you can
1-delete and re-enter the rivarly
2-if you see an opponent who is not part of the rivarly and is facing off one of the rivarly opponents you can delete them off the show and it will automatically add another opponent you can repeat this till you want that the specific character for it.
