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.
Cool team!
You could always go for Sitrus Berry on Snorlax and then you don't need Gluttony since you don't have one like that in-game
also, was the Water Pledge used in Combination with Grass Pledge? because that would be why it wasn't redirected since it isn't actually a Water-type move...
I believe that there are multiple flaws in the team and one is your pokemon don't have the move protect on them which is a really good move in Doubles. I also think that you might not be running the proper sets or offering your Pokemon proper support.
The first thing I would do is remove...
I don't know if you need two different modes as Gallade+Whimsicott and Dragapult+Coalossal are two different types of teams that could easily be built and supported differently such as running Gastrodon to support Coalossal or maybe Dracovish as a good mon to benefit from Tailwind although that...
I think that your problems might be less of an issue with the team, but how you are playing the team as which is something that will come with experience. Leading Togekiss + Weezing-Galar I agree will leave you at a disadvantage against Rhyperior and Excadrill, so instead, I would recommend...
I feel like it would've been useful if you included some Damage calculations as I am not sure what you are EVing for and given that VGC is played at level 50 and not level 100 I am unsure if the calculations would've been correct in the first place, but It would've given something more to work...
The two changes I would make to the team are Mimikyu and Duraludon. On Mimikyu I don't like the idea of running Taunt + Choice Band as that will just lock you into Taunting, at least with something like if you were running Choice Scarf then Taunt would get a benefit of coming out faster vs...
Goodra with Draco Meteor is something i dont like because it wants to stay in and having a lowered Sp.Atk means you will want to switch it out, also does Snorlax get High Horsepower?
