Smash Cadet
Whenever I play as Luigi, it seems I can't get a good finishing move until the opponent is way over 100%. Forward Smash and Down Aerial send them diagonally up and usually don't KO. Down Smash sends them upwards fairly weakly, and Forward Aerial sends them forward fairly weakly as well. The only really powerful move he has is the Up Smash, which is pretty hard to land. What methods do you use for finishing opponents with Luigi at low percents?
