im glad someone else finally see's that sing is better then most think however you have some of your facts wrong, for instance the percents of when you should use sing with the move, as well as the fact that there are some moves that are guarenteed to combo into sing thanks to the ground hitting animation, since if you hit them with sing during this you can actually put the to sleep as well as the fact that some opponents cant punish sing since they dont have a move to punish it, there is also the fact you can ledge cancel this move when recoverying (you have to be close to the ledge though, and has no downsides but is normally better on certain stages since the reach of the ledge and puffs sing is less) anyways hope you edit this guide to include what im saying, btw if you could check out my new and improved guide that would be cool (or play some doubles puff?)
