Tag Team moves.

There’s links in the game so why not tag team moves? If you have a link let’s say DX, if the two people you’re using has a tag team move, it should be an extra move that needs extra charging. And when you hit it, it has a special ability or maybe even ends the match if HP is down enough. Maybe it combines the ability of the two singular finisher moves already in the game for wherever you picked. i.e the pedigree and the sweet chin music.
