A weekly vlog. Dedicate a specific day where your video is dedicated to this concept.
What you think about certain cards/interactions. You're personal progress throughout the game. How you feel the game is progressing. What holds you back. What you think the most overrated/underrated cards are. Whatever topic you want to cover.
This is something that I rarely see out of content producers for other games. However, I'm always drawn to those that do videos about their personal opinions on the state of the game, or certain factors of the game, no matter how vulgar their language might be (maybe it's just because I get what they're saying).
You can have all the pack openings, trade binders, and matches you want on all the other days. That's fine. However, dedicate one day to yourself where you just sit down somewhere, whether it be indoors/outdoors/whatever, think about a topic, and just let it out. However you feel about said topic.
If you're really salty about it, get salty about it on your video. Show some emotion behind it. You're passionate about the game. Show it in your videos.
