I love your idea, but you could make some elaborations on your suggested Bro-mon.
Try to make a post with this format:
- Name of Bro-mon
- Element, for example, foodie, browsarr, or webby etc.
- The description displayed at the back of the card.
- Describe what the Bro-mon looks like.
- Lastly, the Crush, or the rarity of the Bro-mon.
