Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Got to 1500 on a test account using this OU team with the highest tiered mon as Ceruledge and of course I can't forget about Chinese Defensive Salamence

Here's a few teams that I converted to SM from fun old ORAS teams. You might recognize one :)
OU: https://pokepast.es/18a7f573ed13a67b https://pokepast.es/a076a21e349d3b50
UU: https://pokepast.es/7005d38d20e5fe58
and here's if you ever want to play gen 6 OU again. I couldn't convert this one...
Your VGC series inspired me to try it out so here is the first team I've ever made for the format, after a little research of course, https://pastebin.com/GepEPPDR
Haven't given you a team in a while so here's a really fun rain team with a special Mega-Absol and Z mirror move Tapu Koko

Now I know this team doesn't have A-Marowak so it won't be a true Pokeaim live if you decide to use it but it still puts in work http://pastebin.com/QxeuSrMJ
