Say You Got Me is leading the race on top of its group.
Can you play the You Got Me -> with no effect? What if that is the final card?
Can you play Move Any Leading Horse -> on You Got Me and do nothing even if there are other viable leading horses to move (but you don't want to move them).
I had this question today as well. We played that if movement of the lead card is actually impossible, because of creating gaps, you could still play the Move Any Leading Horse and choose the impossible horse with essentially no effect. It would seem to random otherwise. I haven't been able to find an official answer in the forums.
