Command Line for Mastery Emote?

At the end of a match, after the win animation starts, you can't do an emote by hitting control-3 (for dance).

But you CAN still dance, by hitting [enter]/d[enter]

Which means I can do any emote during the win animation...except Mastery, because I have no idea if there's a command line for that one.

Anyone know if there is, and if so, what?
