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.
I'm having trouble determining what to fix, since I can't really find a central goal of your team. Is the idea to be a hazard stack? It seems like a combination of pokemon that suit one another defensively but I don't see a lot of offensive synergy.
Thanks for the support! This looks quite good, my main concern is opposing ID zama. Lando alone is very very easy to chip and takes a lot from Body Press. If you face a sub or tera steel variant, you're probably going to lose. There are a few options you have. You could slap Tera Ghost onto a...
I think your team explanation on pokepaste got cut off, but I think I got most of it. I would recommend HDB over Aguav Berry on Pult, and I'd go Tera Grass or Dragon Gholdengo given you have a pretty rough Ogerpon Wellspring MU. Your lack of powerful priority concerns me a bit as well, Rillaboom...
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.
