Old School Yu-Gi-Oh! Decks
HOUDINI Format
OSY Format
Historic Yu-Gi-Oh!

OSY (Old School Yu-Gi-Oh!) Format, is a fan format in the style of Historic Magic the Gathering, created and managed by us at HOUDINI. The Premise of HOUDINI Format is simple. It's the Goat Format Cardpool, without Delinquent Duo, with 100 additional cards, plus 25 card added every 6 months. This additional cardpool aims to retain the back and forth, slower paced gameplay of formats like Goat format, while offering something wholly unique that doesn't replace classic formats. This also doesn't mean we aim to retain purity of Yu-Gi-Oh! as it was in 2005, 6 or 7. This is a new format that retains the best of the old, with the spice of the new. OSY (pronounced Ozzy) Format has a few additional rules changes compared to Goat format:
