I'm a judge and have seen barely any discussion around Prepared (mostly just clarification around the interaction with.

Rule 722 is the rule for "Preparation Cards", so I fail to see how it could not be relevant.

The text "its spell" only occur in reminder text, which is not rules text and would not be included in template language.

Ah, I have I guess an old version of the CR downloaded from when I was a judge and TO where rule section 722 is "Controlling Another Player," weird reorganization there.

Are you active in judge forums or social media at all? Huge threads on prepared with these arguments (I didn't come up with the idea as I now longer play or judge).

Regardless of whether you think this one example is confusing, WOTC came out a few years back and said they were sacrificing clarity for more natural language as a development goal and it's clearly noticeable in the cards.

Sorry, throwing out a text because its reminder text is a cop-out, that's the only way 99%+ of players are going to interact with the rules. The rule makes sense when demonstrated but from a logical step-by-step when following what it says on the actual cards it does not actually function in a way that conforms to the way it is supposed to work.

		I'm specifically talking about the use case of "can we use natural-language tools to parse oracle text and produce functioning game objects in Arena". For that use case, it's completely sensible to look at the actual rules text and not reminder text. Looking back further, there was confusion during preview season when people were looking at "fake/leaked" mockups that had incorrect text on them, but this also isn't a problem for the issue of "WotC themselves writing systems that can parse card text".
