So... I didn't know about Regulation J. Where can I play Reg H?

For context here: I am a casual VGC enjoyer. Every now and again I get the itch to play VGC and climb the ranked ladder in-game. When I got news about Regulation H coming back, I was pretty excited because I really like a lot of the Pokemon in that format, and started playing again to build a team to climb ladder.

Of course, the only issue is... Regulation H is only for official events, and Regulation J is being used on the ladder. I found this out later after I had settled on a team. I was pretty disappointed because putting together a team was a pretty painful process. Regardless, I am also putting together a Regulation J team so I can climb ladder anyway.

So, I know I missed the tournament/event over the weekend and that's okay. I am not really interested in playing on Showdown. Are there any other spots to play Regulation H? Are people queueing Reg H in the casual ladder in-game? Or do I have to look specifically only for official events to play my Reg H team?
