The Undertaker vs Daniel Bryan at Wrestlemania: Making it Happen

There are two sides to this story.  First of all, The Undertaker needs to return and win both the Royal Rumble and the World Heavyweight Championship before Wrestlemania.  This would cause the Royal Rumble win to become null and Daniel Bryan would be able to go one on one with him for the title by cashing in the Money in the Bank briefcase.  The second side to the story is simply making it believable.  Can this vegan nerd with no TV in his house end the streak?  If you'd ask anybody in their right minds today, the answer is absolutely not.  That's where the creativity comes into play: we need to build a ruthless, aggressive, submission machine with what we have in Daniel Bryan.  This post will be my fantasy booking that will lead to The Undertaker's last ever Wrestlemania match, and Daniel Bryan's FIRST ever World Heavyweight Championship.
