#1 Should do: Firefly Fun House on NXT
Last week on SmackDown, NXT Superstars invaded the show as Triple H claimed that they are ready for a war. As mentioned earlier, The Fiend may have to face WWE Champion Brock Lesnar and NXT Champion Adam Cole at Survivor Series 2019. While that's not necessarily the best idea, it could lead to some great moments during the build-up.
If that's the planned match, Bray Wyatt shouldn't wait to do a firefly funhouse episode on NXT. After Adam Cole wins a match or while he's cutting a promo about Survivor Series, he could be interrupted by Wyatt. The latter hasn't appeared on NXT in years so, he'll get a major pop from the fans.
It could just be a way for him to warn Cole and the rest of the Undisputed Era about the dangers of crossing The Fiend. This will be an interesting segment, and most importantly, it will be different from what we usually see in NXT.
Simple ideas like this could make the build-up to Survivor Series much better.
