hahaha only a REALLY EFFING CRAZY ONE!!! I'm known by my friends as a dreamer when it comes to smash...always have been, esp since I picked up Ness, haha. But I'll dream of the most ridiculous stuff, until they actually work. Like Spike/Star Jacket --> PKflash which I've probably mentioned, not to gloat, but just to talk about a crazy trap.
As for a RIDICULOUS idea for the dsmash: when you have the spike jacket, have your back to the edge when the opponent is recovering, if you're good at timing your dsmash, make sure you hit them with the very first hit of the yoyo, the strong hit. if you've spaced yourself well enough and timed it perfectly [haha, crazy, I told you].................THEY GET SPIKED.
For those who don't know, when you have any of the three jackets on, if you upsmash or dsmash, the very first hit of the yoyo carries the properties of whatever jacket you had on [and of course, after you execute the move, the jacket is gone]
