Maybe sucker punch Darkrai? I know that sounds like a meme, but its not a bad set. Tera fighting dozo already can kinda beat the gambit set, and offensive pressure with glowking still works fine enough unless they are running protect blissey. In exchange, you get a really fast mon that can revenge kill a lot of things. It doesn't have the sheer power of gambit, but it still works well enough to kill chipped mons.

It's more of a niche set, but it does work wonders if you can position it well.
Thanks for the reply and interesting suggestion.
Unfortunately, Darkrai can't switch into mons like Ghold, Pult, and Meow multiple times throughout the match so the team will start to fall apart defensively.
One mon I forgot to mention is Rillaboom, my Gambit is EV'd to always live two banded Wood Hammers. This is crucial in situations when you don't want to tera Dozo.
Alongside Waterpon, Boots Gambit (great item on this mon btw) is the main future sight abuser. Non-tera dark Dozo, Zama, and Tusk get shredded by future sight so there is great synergy with Gambit. The team needs two future sight abusers since Waterpon is vulnerable to hazard chip, so it often can't last the whole match against stall or position correctly if you have to keep removal in mind.
Together, Waterpon and Gambit + Future Sight cover the stall matchup really well. Stall Dozo and Mola needs tera Grass/Dragon to beat Waterpon and Tera Dark (more common than Fighting) to beat Gambit so they'll lose to either one or the other.
When I made the team, I was aiming at making a balance team that matches up well against stall, which is notoriously a difficult matchup for balance. I credit this to getting me through the "treacherous 1700s" where stall seems to be rather common.
Regardless, that Darkrai set sounds fun and I'd welcome you to try it out on this team. If you do, let me know how it goes!
