Interact with and contribute to a niche community like this one and get noticed. Articles, guides, witty conversation, whatever make you charming and/or helpful, make it visible in lots of relevant discussions. Have a unique and hard to miss logo as your PFP that people will associate your actions with. This will organically get the attention of people, some of whom will give your content a chance. Then it's just a matter of making good content that people stick around for.
If they view you both as a good person and a good content creator, now you have a cult following, some of whom will be either people more popular than you who will shill you or people who are talented and will contribute assets like art and music. They'll want to see you succeed.
But the most important thing is that it's all organic. If you're doing all of this JUST to get noticed and not because it's fun, you'll burn yourself out and people will notice. No one likes a poser. It needs to be sincere and not a cold, calculated marketing stunt.
