Hello! I'm pretty new to MTG and collecting cards in general. I've been given some old cards and came across this one.

The card shows as a Forest and online all printings of the card are green. But as you can see, mine is almost a bright blue colour. I'm wondering if this is just an age thing, maybe light exposure? Or if its a misprint or potentially just not a real card.

Any info on it or if anyone's come across something similar, that would be great!

Thanks!
