My general strategy is to lead with Great Tusk for setting rocks and going from there. I've gotten a lot of success from Toxapex as a catch for tanking hits. Chandelure and Iron valian have been useful for poking holes or even sweeping, but sometimes i struggle to get them in the field. I use Tusk and Lando for chip damage with varying success. Last but not least Kingambit for last second sweep which has been mostly successful if its not against more than three mons that dont check or counter it.

I've gotten pretty much break even results for wins and losses while playing, and Im looking to improve this team. Any and all tips are welcome!

Hi, welcome to Smogon! I am locking your RMT for the time being as the forum rules require that you provide at least three lines of descriptions for each Pokemon to explain their roles. Please read the rules carefully and look at Team Showcase to see the detail we require. PM me with updated descriptions, and I will be happy to unlock this. Also, feel free to PM me if you need help or have any question. Have a nice day!
