Hey there leobazooka, welcome. You might be color blind my good sir. 'Til next time.
Yeah, fairly certain that’s just a regular card. It’s funny though because I remember encountering a Zigzagoon in X/Y while not looking at the screen and having to google what color it was supposed to be because I was paranoid it might’ve been shiny. Turned out it was just a regular one, but it does seem like the brown on Zigzagoon has been depicted in various different shades of brown so we’re not completely crazy.
