Misprint?

[thepeppokemon]

I have a magikarp from FR/LG and it is supposed to be a common but has a diamond. What is up with this?

It's a common misprint; the reverse holo version of the card had the correct rarity symbol while the non-foil version had the incorrect one.

Nothing to get excited about, all of them are like that...
