Sun stall is not a new thing, it's an established playstyle generally known for almost a year, Stunt's laddering with it generally spread the word and even before then it was used. It's very very effective. However you will get destroyed by other sun teams rather consistently, if you're going to act like threats such as Scarf Darmanitan won't take out most of your team on it's own once Tran is gone or that it needs a post much longer than this you aren't helping anyone reach a greater understanding of it. It'll do just fine against other teams barring Sun offense, and that's how its always been.

Edit- I thought I may as well throw in since I haven't seen it anywhere that Sableye is your 2nd required member if you want to have strong matchups vs other teams- nothing spins on Sableye in sun and it isn't as bothered by Scald. Not using Sableye on Sun stall would be like not using Torn-T on rain.
