Hello, I am an regular swashbuckler pvp. I am not very good however and i need some help! I currently have fan, toro, and sarah as companions and all the friar sand gear but the robe, I have a revive eye patch and I am max level. I really want to become good at pirate101 pvp so please, help me! Thanks!

After two to three years of being in Pirate101central instead, I've decided to drop by because I usually don't have a membership. However, I do have a max level swashbuckler as well. First step is getting the right gear. In my opinion, gear that gives you:
2-3 assassin strikes
1 extra hide
2-3 valor fortress
1-2 revives
1 reduce accuracy charge (can be from pet)
...will help you a lot. It's a luxury, but if you can, try to get Purge Magic from Bishop since it helps against all of the shields.
It takes time to create a good pet, and I think you're already on top of that, so now the strategy. I can offer you mine, but I think you should take a trip to Central for Technomage's recommendations (he's better than me). There are many guides there for all of the classes.
