If Marth uses his over-B combo on Luigi's shield, Luigi can drop shield and jab between the third and fourth hits.
And I'm sure Luigi mains know what to do with a jab.![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I believe he can also usmash OOS (i.e. jump-cancelled, not shield dropped) and maybe nair.
Test and see if there are any other interesting punishments you can come up with.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
