You can patent game play in the USA. Wizards of the Coast used to have a patent on turning a card 90 degrees. It has expired.
Considering Yu-Gi-Oh had that mechanic for monsters in defensive position, that must have expired at least 2 decades ago. Unless Yu-Gi-Oh's implementation was different enough that WotC's patent didn't apply.
Yeah it was different. The patent wasn't for a defensive position, more like when a card was was used up
