So maybe, it's not The Beast in the Bank but the Beast's advocate who could put on the referee's garb and call the match at WWE Stomping Grounds. Why this is interesting is because Heyman can call the match in such a manner that it favors Baron Corbin and not Rollins. And then when Corbin wins the match, Brock Lesnar cashes in on him.

I like this idea because it will be a storyline twist and it'll also be something that nobody will see coming. Heyman is also a fantastic character and he can be an over-animated figure when the situation calls for it, which can add a whole new dimension to the whole match. Also. the sight of The Beast coming up the ramp is scarier than him being in the ring from the start.

Or maybe Heyman stops the cash-in. And then Corbin becomes his brand new 'guy'.
