Cards like Morphing Jar, Cyber Jar, and Fiber Jar were staples of competition for literally years, and none of us really noticed how insane that was at the time. If you're an old school duel fan you probably have your own fair share of memories about at least some of these abominations, but if you're a bit of a newer player be sure to strap in and fasten your seatbelt before pressing Play on today's video.

Seriously, how was ANY of this allowed?!?

For the older members of the audience, what are YOUR favorite memories about the Jars? Let us know down in the comments.
