Honestly, Reigns vs Lesnar kills some of the hype for me, but I'm still very excited to see how the build to the rest of the card shakes up. This is just a rough idea of what I think the card will look like for the Raw side:
- Cena vs Taker
- Alexa vs Asuka (maybe Nia if Asuka goes for Charlotte)
- Miz vs Strowman
- The Bar vs who knows
- Elias vs Finn
- Rousey/Angle vs Steph/HHH
The last one is just a way to get them on the card, I think Elias could use a Mania match, especially against someone like Finn.
As for Smackdown, who fucking knows at this point? Besides Nakamura vs Styles, I couldn't tell you a single match, and that isn't a good thing, because there's nothing there for them to make happen at the moment. For RAW, you have hints of feuds here and there that they've been building for a while, but Smackdown just reeks of being written the day of the show half the time.
