I don’t even know if that will work, you have to kinda intentionally lose some matches but definitely win others. The most obvious solution is to lose any World title shot you have, win the Royal Rumble and lose any World title shot between then and Wrestlemania. At least that’s more or less what I do. Winning the RR is a major bitch since there is no dedicated “throw opponent over the rope button” you have to just strong punch them which can be easily countered and lead to being punched out yourself. So the RR is where your going to have to do the save scumming
