I have an idea that was inspired by Dark Energy. It is in regards to a potiential kill set-up.
I have no way to test this at all, but it was an idea that I think might work. Falco can force ground releases from hit grab by mashing pummels. This breaks the opponent a set distance from falco. If I recall correctly, the frame advantage for the break away is zero for both characters.
What if falco puts up his shield immediatly after the break? Often times you might catch someone trying to button mash, they break out and do not realize it and end up doing some move by mistake. When that happens, they might end up attacking falco's shield, and from attacking our shield, we can OoS Usmash.
What do you think? I can see some obvious faults with this depending upon grab ranges, but if the opponent reaches out first, you could still hit them if they whiff because the would be leaning forward. Others would be obivously shielding themselves or rolling, spotdodging. But, the idea is to provide some random set-up they might not be prepared for.
