>>42699665Don't use sash Exca unless it's a lead for an HO team. A sand Bulky Offense like this would prefer an item like Balloon/Leftovers/Lum or even Life Orb.
Speaking of Life Orb, it's generally a pretty bad item for a lot of Pokemon including Crawdaunt. You'd be better off changing it to Band/Mystic Water/Black Glasses/Lum.
AV Ttar sounds like a good idea, but in gen 8 it doesn't do a lot that other Ttar sets wouldn't also do. If you're getting messed up by Dugtrio stall then Shed Shell is an option. Otherwise a safe item like Leftovers is fine.
The other sets look okay but I don't understand how you're struggling vs stall. Your team is very offense by Gen 8 standards, if anything there aren't enough defensive pivots on this team. A well played LO Clef + Crawdaunt should be enough for most stalls. Post a vs. stall replay if you can.
