Well Pit might be another good character to bring here. My reasoning behind it, is that Pit can't really fully utilize his gliding capabilities thus leaving him with an even more so predictable recovery. His arrows don't serve much seeing that in the first level arrow looping, arrow chasing (or any other arrow trick) will be blocked by the top platforms on the first level. In the second level, the statues serve as a protective barrier against those to. And the third one would neutralize horizontal arrows.For who to bring here, spacies for what Nintendo said and Lucario because it can be good at times.
Also another thing to add is to use the transitional parts of the stage. If you can memorize where you would be after the transition, you can use it towards your advantage. Like if your opponent is standing on the left of the stage and you wait in the center of the transition, then you will know your opponent's current position which will be on an above platform while your on the lower platform to position yourself if your opponent decides to drop down, or catch them with an U-air (or whatever best fits the situation).
Well that's what I can think of after just waking up.
