Updates to the Team
1) I have switched out Choice Scarf Terrakion for a Choice Scarf LAndorus, for more Sand abuse power and a better late game sweeper thanks to Pocket.
2)I have added Hidden Power Fire on Metagross thanks to Pocket so I won't be walled by the steel types (Scizor, Skarmory, etc) that are annoying who can wall Metagross.
3) I'm still testing out the other Trick Room sweepers Marowak and Rhyperior that Pocket suggested.
4) I have dropped Energy Ball on Reuniclus for Focus Blast to hit Steel types that are weak to fighting type moves.
Hey Sciztar your team has gotten better since the last time I rated it, if your having problems with Slowbro you can add Grass Knot on Metagross. But I would look into adding Rhyperior on the team, it greatly appreciates the boost from the sandstorm. You already have Gastrodon as your water team counter so this would work well and really appreciate the Storm Drain boost. Also I think you need to get a defensive Bronzong like what Pocket suggested.
