Shiek got a serious upgrade to her already great arsenal of attacks. She can now use her chain whip to grapple onto an edge. If you're not quite close enough to grab on, use the Side+B move to sling out the whip and latch it on. Then while hanging below the ledge, press the A button to pull yourself up and grab on. From there you can roll up past your enemy or flip up into an attack. Either way, you have a much better chance of getting the upper hand than if you tried to land on the ledge where they are waiting to juggle you. I always go for the ledge grab for this reason.
