A no-brainer here......
Yoda and clone 2 pack where Yodas green saber can be inserted into a hole in the clones chest, and you can attach yoda to the clone by him just holding on to his saber.
pack it as a 2 pack, and pose it in the card just lkike the scene where he throws his saber through the clone and retreives it. Best scene in the movie!
I was also thinking 3 pack with Yoda standing between 2 clones loo, one with a detachable head, and the other like the one I decribed above.
(well, that and the clone jumping on the crab droid.)
