good platforms really help. I've found a lot of people like Pokemon Stadium 2 because of it's low platforms, which can be used for a lot of different things (I have trouble explaining what they do exactly, hopefully someone else can explain. The idea is they give you more options and allow you to camp, approach, and run away more easily.) Also, when the opponent is on a platform, you can easily jump-->bair chain (or whatever aerial you want to use.)
I personally really like Distant Planet (though it's my favorite stage aesthetically, so I might be a bit bias). You can full hop-Uair the highest platforms, and if I'm not mistaken, you attack through the platform without getting hit yourself. It's nice and long so you can camp if that's your thing, and you can chase people who are on the platforms with aerials. Maybe it's not the best stage, but I think it's at least pretty good for Tink.
I know there are other stages but I don't have my Wii with me on vacation so I can't check things...
Those are the first two that come to my mind, anyway.
