I've read your request in the workshop twice now and still unsure how you want the banner to look. Out of the examples you mentioned, Nidoqueen seems to be a nice pick as a mon literally standing in a bazaar stand since it has been UU most of its existence (and the gens it wasn't it was still usable there), so that's one approach off the top of my head. If you want your description to work, I need more details.
