Using your Klaw is absolutely awesome though. It puts pressure on DDD and infinite jumping makes a pretty cool approach. Plus, with it, shielding becomes useless. If he tried to dodge, then you can use a tilt or something.
And of course, FIRE!
If DDD spot dodges, just jump away if your klaw jumping lol. He won't be able to shield grab you at all. I wrecked Atomsk's DDD by doing this, it was a friendly, but regardless it works. Considering I mained DDD for such a long time I know DDD really doesn't have that much to do against klaw jumping except running away and spamming waddles or bairing, but if hes bairing then he's off the ground and at a disadvantage.
