Call for Judgment

Squirrel gave himself 1 Air and said, in the GNDT:-

"(Retroactively change one of the Swirls to being cast by my new Stone Head. Not technically legal, but I could have done this at the time and forgot, so it's not exactly cheating either. Feel free to CfJ.)"

Come now. Given that "forgot" means "didn't think to", this seems a bit cheeky - if you make a move in a game, that move should stand, even if you realise later that you could have made a better one.

I suggest that Squirrel be forced to lose 1 Air.
