When you think Wrestlemania, and winning, there is only one man that should always come to mind...
I was surprised, at every six packs, that I didn't see one until now from this insert set. I guess the pack I pulled from the last blaster must have had the only one from that box, but here, we have card #10 of the 10 card insert set - The Deadman.
Sure, he eventually ended up with a couple losses, but The Streak will always be his and one of the greatest accomplishments in wrestling. Sure, wrestling is "fixed" and is just "entertainment", but there still has to be reason why the man went two decades without losing at the biggest show of the year.
My understanding is that it was well past 10-0 before it became a thing that was thought about backstage, so just even considering that, there's reason he went that far.
Wins and losses may not mean everything, Triple H has more Wrestlemania matches than the Undertaker, but is below.500 - doesn't really take away from his career, but they can used as a way to define an aspect of a wrestler. That;s why, when you think Wrestlemania, you think Undertaker.
