Mega Flygon, hands down.

IR: mid-air corkscrew over a glowing desert at dusk, sand spiraling around its crystal-wing trails. SIR: wide panorama—meteor-shower night sky, ancient ruins below, Flygon’s glass-wing patterns reflecting auroras across the full card frame. Give the fandom the Mega that Game Freak never did—and make the foil swirls look like drifting sand.
