I Haven't Played Pokemon Showdown in 5 Years

My first video on this channel was a Pokemon Showdown Let's Play video. At the time I was a scrawny 16 year old kid with an extremely unrealistic dream. I received some good feedback on the video (YouTube deleted the comments unfortunately) but I was discouraged and quit.

This was the biggest mistake I have made in my life.

But how much skill do I still have left? I used to be extremely good at competitive Pokemon, holding my own in Smogon tournaments when I was only 13 years old. Do I still have it?
