As puff, you need to control air space, especially for sheik. If shiek gets a grab and you cannot reach in time to rest, have sheik down throw and re-grab until you get close enough to rest. Puff should also be the one to go off the stage to edge gaurd while Shiek stays and covers the ledge. Jiggs should look to combo oppenents into sheik. A good example of team chemistry would be M2K and Armada, even though neither plays puff. Watch Armada to see how he plays a character that works nearly identical to puff when teaming with sheik.
