Mm, looks pretty tight, but I don't think this will be able to be used often in competitive play.
1) You don't see many Falco's or Pika's in dubz, or even together lol.
2) There's ways around it I'm sure.
3) You have to read what they do.
Example, Samus and Pika against a Snake. Samus could have charged a shot, but instead tried going for the spike, the Snake uses his cypher and moves toward the end of the stage. You could have had a charged shot for him, blasting him into kill zone.
The only way I see this to help for Falco is for lasers gimps and spikes. But using it correctly, don't you have to powershield the Thunder? It's not hard at all, but you won't get it everytime.
Nice find none the less.
