Let's get Yondu in here.

He is a great character and looks like he may have a larger part in the next guardians movie.

Ideas for some moves...

His whistle lance thingy.
Obviously it would be some kind of targeted destruction of tiles.

Boobie Lou boo boo. (One of my favorite scenes in guardians with him interrupting the merchant over and over.)
A passive that lets him interrupt an opponent's move once he has collected enough ap. Basically the opponent uses up the ap to smack you but Yondu interupts them canceling out the move entirely. Also uses the ap Yondu collected to trigger it.

I'm not sure on the last power. Maybe something involving his dashboard collectibles somehow.

The next hint for a new character seems like it could be Yondu. I hope we get him.
