Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
It's definitely not a terrible team and it CAN work but it feels random and has a decent bit of problems, for instance you'll get absolutely destroyed by hstack
I'm having a lot of trouble grasping what this team is trying to do, there is decent type synergy but as a whole I can't see how these pokemon work together, could you explain your thought process?
Climb ladder without using Tera? Yes, definitely it is. The fear of Tera will help you out a LOT though, if your opponent knew you wouldn't use Tera, you would be at a major disadvantage.
Sinistcha being your water resist is pretty rough, a Walking Wake would run through this team. Lacking a fairy resist is also a major issue, if you face an Enam / Ival you'll be toast. Having a resist to every type on a balance team is non-negotiable.
With that being said, I would probably recommend rebuilding (unless the team has some direction or goal I'm missing). Good luck and feel free to send once you rebuild! :]
You've done a good job of matching sets with playstyle (all of these pokemon fit on bulkier balance teams), but there seems to be very little synergy between the pokemon. As I said in the video, you can find a reason to pair any two pokemon together, but really solid synergy works on many...
SD Gliscor is best on hazard stack, it's not terrible outside of it, but it's an odd choice and I can see why it doesn't feel right. Lack of hazards is also a major problem here. You have a lot of pokemon that take advantage of hazard chip and nothing to set it.
HO generally doesn't use pivots. If you're having issues with Zamazenta, try transitioning to a Special encore valiant. I'd recomment CM MB Shadow Ball Encore
I'd say tera fire leftovers ideally
And yea dualstatus hex pult is very difficult to handle, no way to fix it with just 1 mon unless you slap on a garg somewhere
