I agree with ShadowLink. What he said is sorta what I was trying to say only he said it a lot better and more clearly. I figured you could probably do it without an opponent being there, but that it would be REALLY hard, but I wasn't sure. I think that actually clears this up rather well and now opens it up for us to figure out just how we can implement this into our games as far as getting an opponent near a ledge to get ourselves in position for it.
First I propose downthrow. Down throw your opponent so that they end up near the ledge and then immediately start charging a spin dash or spin charge. If they do a recovery attack, you can just shield cancel and run in for a grab if you are using spin dash, if you are using spin charge then just try to let it go and see if you can hit them and if you miss then use the spin dash next time. If they are smart, then they will not roll toward you. If they do, then they get hit when you let go of the spin. If they stand up normally, then hopefully they are close enough to the edge. If they roll back trying to get those extra few inches, then that is ideal. This would put them right where we want them to be and will let us use this SDRUT to land 19% on top of the % from the down throw and as many pummels as you got going into the down throw. Sounds like this could be a quick way to land 30% on an opponent.
My other idea is that we do this on Smashville's moving platform. I'm assuming the timing for this is probably rather hard. So, if we mess it up and we start our turn too late, them maybe we will instead end up with the SCROO. Win-win.
Any other ideas?
