What would you do?

No way it's going to be a misdeal if you waited until all the a cards were dealt out to speak up. If you'd said something as soon as seat 9 got his first card, then maybe.

But even then, I believe the misdeal rule invovles a mistake on the first two or three cards. As described Seat 9 is the fifth card, so the dealer would probably have just continued to deal and then killed the hand anyway.

But again, there is no way after people have looked at their cards (and even if you hadn't, the dealer couldn't know this for sure), that the ruling should be for a misdeal.
