Hi MrSvancy, 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 the 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 questions. Have a nice day!

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?
