I think I got an easy-hard way to chain throw heavies now. it's kind of hard to do it though since... well, er... it's hard online and the timing goes off... but it racks up damage fast plus it looks flashy IMO.
"Non-Moving Ice Climber Fast F-throw Alt Throw"
I know it's a bad name but the italics give you the idea though; I'll explain that CG applies that:
Description: This CG is similar to the "fast b-throw to f-throw" when you f-throw fast. So, this is just an f-throw alt throw.. BUT... you will have to do it fast enough to flick the control stick forwarc and Nana and Popo shouldn't move when alt throwing with this and it's very hard to pull off; but you actually, you can make them move a bit if you want, it's just that I wanted them to.. not move when doing this CG and I wanted this to be like Dedede doing a standing CG. ._.;
Did I mention it only works on fatties/heavies? It might only work with Donkey Kong, Bowser, and Dedede. Except that, it can't work with R.O.B though, the ICs' grab range/their hands are too short to reach R.O.B...
Maybe it can work with other characters that the ICs can reach their grab within the other characters, but Nana and Popo will move a bit from the f-throw when doing so.
Eh, just.. telling. ^^;
