I remember when I was a kid, I'd come home from school and watch this anime/show about this boy trying to find his missing father that dissapeared all of the sudden, leaving behind these playing cards that can summon beasts/warriors (?). The boy knew his dad would leave these cards behind as clues where he could be found, or as breadcrumbs leading to him. The premise was not unlike that of Yu-Gi-Oh, he played games that were card based, however it was distinctly different in style and monsters, I remember CGI being used.
Can anyone help me recollect what it was? I remember it frequently, however I can't seem to find it with the regular Google searches
