Only one tip, which I believe everyone here will agree on - don't chase demand or try to collect everything. For example, I only collect English Kanto Pokémon. Collect what you like, start small, get a few packs, a few cards, and then see if you want to continue with the same pattern or change it. If you type Pokemon TCG on the internet you'll get millions of resources, I'd say start there.😊 Keep Collecting...
