Well, I got a couple confessions I can get off my chest:
1. When I finally learned wavedashing, I'm trying to learn to use it consistently and also not use it too frequently, as I have been using that a lot over dash-dancing. One example would the SDs I sometimes get with Yoshi (even though he's the best character I can perform wavedashing on, followed by Mario).
2. This one is about the spacies. For Fox, I don't play as much because I don't know how he works, but at least used the down-throw quite a bit to do (from ledge) KOs, and sometimes try to edgeguard with his shine. Falco, on the other hand, play more often, and play more better. I frequently use his down-aerial a lot either as a combo starter, finisher, or an extender, but mostly the latter. At least half my combos with Falco have at least hit with a down-air--either after a shine, juggle, or rarely a short hop.
I am a casual, these techniques competitors use surprise me. When I perform it, it's an accomplishment, even if it costs me in the end.
