Here is a random card...
Opening Match:
Rey Mysterio Vs. Cody Rhodes - If Rey loses he has to take off his mask. If Cody loses then he has to WEAR a mask. Rey wins and Cody doesn't get to use the "Dashing" gimmick for awhile.
The Corre Vs. Nexus - 4 On 4 Elimination Match - Wade Barrett, Ezekiel Jackson, Justin Gabriel & Heath Slater Vs. David Otunga, Mason Ryan, Perfect Jr. & A Surprise New Nexus Member Skip Sheffield. I think after all is said and done, Barrett gets left with Otunga & Sheffield. Sheffield turns on Otunga and leaves the match, getting counted out. Barrett gets his revenge on Otunga and wins the match for The Corre. Sheffield moves on to be a Face on RAW.
Money In The Bank - 5 Guys From RAW and 5 From SmackDown. Big Show, Chris Masters, Jack Swagger, Kane, Christian, Alex Riley, Evan Bourne, John Morrison, Mark Henry, R-Truth. Though I could really see John Morrison winning, Christian could win to set something up with he and Edge, or even with Del Rio, since he and Christian have some history.
Bill Goldberg gets announced for the HOF in the next couple weeks and has his final match at Mania.
Bill Goldberg Vs. Chris Jericho - This would be an ideal match for Goldberg. It is someone that can make him look really good in his last match. Plus, there is a WCW tie in that could really get the whole thing over, especially in Atlanta. Goldberg would win of course.
Dolph Ziggler Vs. Kofi Kingston - The IC Title would be on the line. They would probably have an awesome Mania match. Maybe this is when Kelly Kelly turns Heel here and helps Vickie, help Ziggler or something like that. I think Ziggler should have a big Mania win this year. This could be it.
Ted Dibiase Vs. Daniel Bryan - US Title Match - The Bellas join with Ted Jr., and that could be built on. He has the money and they are Heel, etc... This match could go either way, as they might want to start a push with Ted. Or they could have Bryan extend his winning ways and let him get his first Mania win. I think I would give it to Ted Jr. and see where they can go with it.
Sheamus & Drew McIntyre Vs. Santino Marella & Vladimir Kozloff - Tag Team Title Match. Kelly Kelly makes her presence known again as she helps Sheamus & Drew win. She hits Tamina, who comes down with Santino of course. This would be a pretty quick match. Sheamus and Drew win The Tag Team Titles.
CM Punk Vs. Randy Orton - I think Randy Orton wins this match. They could have another shock factored in as someone new helps Punk and joins Nexus or maybe Husky Harris returns. I think Orton should get this win though. Unless they come up with a good way to screw him over.
Edge Vs. Alberto Del Rio - World Heavyweight Championship Match - Edge ends up getting the win and Christian comes down and cashes in MITB. He would be successful and take the title away from Edge. Even if Del Rio won, it would be awesome if Christian cashed in. Against Edge, and being successful would make a huge impact. It would depend if they wanted to turn Christian, or keep him Face, as to who won the match before hand.
The Miz Vs. John Cena - WWE Championship Match - I think everyone assumes this match will take place and The Miz is just being fed opponents to keep the title on him, so this match can happen. I also think most people assume John Cena will be the hero and dethrone The Miz. But what if he didn't? They have Miz pull out another victory, just to lengthen and legitimize his title run.
Triple H Vs. Undertaker - Career Vs. Streak - No surprise that Taker wins this. I am not really on board for the booking of this match. But, nonetheless, it won't be a bad match at all. I think they will end up putting on a great, emotional match. But, Triple H will fall.
