I just used Cloud because I wanted to use him. I don't think I used Cloud the last time we played. His sword reach does work well on Game and Watch I seen. I also expected to see Duck Hunt at some point, so I switched to Mario for game 3 because I thought it would be a better counter than my Cloud or Yoshi.
After seeing your other comments I can see how your smash spirit would be less. You never know how people would react by losing. I've seen some really salty players on For Glory. (one of the reasons I don't play For Glory much) I find that playing against players that wouldn't get salty for losing or just playing with friends is a way to increase spirits in general. I generally don't play well if I am mad.
