6. Brock Lesnar vs The Undertaker
Remember how crazy the Internet went after the confrontation between The Undertaker and Brock Lesnar at UFC 121? By WrestleMania 29 it will have been almost two years since the (was it worked?) confrontation but it wouldn't take much to reignite the flame between the two former adversaries. Whether or not there is legitimate beef between the two a battle between the two men would be colossal, even more so if it were given an MMA style twist. It's likely Lesnar's final WWE outing so what's it matter if he taps out to the biggest Legend of them all on the grandest stage of them all?
5. CM Punk vs The Undertaker
The Best in the World versus The Streak at Wrestlemania? We know we'd pay to see that match! Earlier last year there was legit talk of a Punk/Taker clash at 'Mania and with Punk out of the WWE Championship picture post Rumble (possibly) who better to face 'Taker than CM Punk? The last time these two faced off Punk was a babyface champion who had yet to find his stride, in 2013 Punk is a legit bad ass with some serious victories under his belt. He also has the respect of The Undertaker so who knows perhaps Punk could be the man to end The Streak once and for all? There's scope to involve Lesnar in this feud - and Paul Heyman has been a great mouthpiece for many of Undertaker's former adversaries. If any one man was going to help Undertaker steal the show for a 5th year running CM Punk is that man.
