Hey my name is Hans and I used to watch a show on fox kids that was about cards.
it was about monsters that if you killed them (or something) they turned into cards. and then you can eat them up and you will transform in a stronger monster. I know there is a serie about this but I dont know what it is called.
shows about cards I know are not it:
Mon colle knights yu-gi-oh
If anyone can help me that would really be appreciated
