The likes of the new Edge of Eternities Special Guests, with their retro poster look, totally change up the typical structure of a Magic card

And the artwork is split across two cards for maximium artistic potential (probably)
There seems to be a shortage of them everywhere, and I had to visit three Pokmon Centers last month before I was lucky enough to find one where the newest expansion packs werent sold out
