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.
Mazz, do you have all nine games scheduled? You posted that you were attempting to schedule with your opponents in the main thread, but your pool leader has said that he has not been contacted by you. If you are not able to get your games done please let me know ASAP, so I can make the appropriate substitute.
