When I first read this I thought it was a graphic+text activity, as in design the card itself and then explain it. Re-reading it I think it's just a text explanation or is it both or either one?

I think this had been my original plan when I submitted to the System, but on considering my situation for the month, text-only would have been more practical for me (less coding to worry about, etc).

This said, I won't penalise graphics. Just make it no bigger than... idk, 300x300? It should be clear enough what the suit is from that, anyway, so long as description supplements it. :)
