Hi, 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. Alternatively if you just want some quick tips feel free to post on the RMT section of the smogon discord.

How to PM someone on Smogon

To PM someone on Smogon, go over their name on any of their post. It will display a little pop-up with a summary of their profile. Then, hit the "Start conversation" button and you will be able to write a PM just like you write a regular thread.

Tips to help get 3 lines of description

Why did you choose this Pokemon? What do the EV spreads do and why do you have it? What are all 4 moves for?
