The Chariot.
I didn't like the design of the original card, with the flat chariot front and center.
So I started looking into Triumph Arches, and found out that the one in Brussels has a chariot on top of it, perfect!
From there I copied that one, added sphinxes like in the original card, and then filled in the rest with some star-chart looking stuff and cobblestones that make my hand feel like it's going to die.
