I would focus on getting one right and then put one in each card and agent will format the other 29 for you. and put something at the top that pops, like a hero image that's a collage of everyone else's photos and their common tread.
In my head I'd imagine a 2-col layout with a large photo on one side and a few sentences and bullets and a link for more info would look nice. you could also put a long horizontal smart layout with small bullets across the whole card with key facts.
