I mean, basically, you just gotta know more people and play with more people. Finding someone that is completely in sync with you in terms of skill and schedule is incredibly rare, so you have to make up for it with having just way more people to play with when you want to.
There are three avenues to look into: locals, online communities you’re a part of, and online communities dedicated to the game you’re playing.
Locals depend entirely where you live. Growing up in a town of less than 25,000, it was pretty much just who I went to school with and who I knew played video games. Going to a city of <million in uni, I still had to be the one to start and run both local monthly tournaments and weekly meetups (where people just play casual matches/money matches/train etc). But you might luck out.
Of course if you live in a large centre though, just search around. There are probably dozens of meetups every month.
Now that’s, of course, during normal times. In our current pandemic, nearly everything is transitioning to online. Search for those local communities, but also ones that are near you (a state/province or two over, etc.) that you could connect to with a decent connection. I guarantee way more people are up to playing online matches now than ever and, unless that community is run by complete assholes, no one is going to balk at new players joining and looking to play a few matches, in person or online.
Another avenue is to look through other communities you are a part of. Here, for example, but also the discords (like Waypoint’s!) and such. Your mileage will vary greatly and you’re not always going to find people who are the most skilled or dedicated, but you’d be surprised how many people will play even niche games in communities of all sizes.
And if you just want to jump into the deep end, there are tons of discords for fighting games in general, for every niche game you can think of right down to discords exclusively for one character in one game and that’s it. These will be the people who are most dedicated to the game and probably willing to play the game the most, but are also more likely to be a) way more skilled than you (which can be discouraging when you are fighting someone and losing every match) and b) not moderated well, so you can encounter the worst of the worst on it.
No matter which avenue you take, good luck. If you’re looking for nearly daily training, it can be a lot of work just to set things up. But the good news is that now there will be more people than ever looking for the exact same thing, especially in a game that’s still relatively new like UNICLR
