What Kirby powers do you like using?

I don't need to ask if any of you guys played the games of a certain puffball, but I am wondering what copy abilities you really like using. Sure, I know that the Hammer and Stone abilities often come to mind, but what about the other ones that do not give you an unfair advantage in boss battles?

For me, I really like the Ninja ability. It is fast with attacking, has plenty of cool tricks (and an awesome katana in the more recent games), and it's based on ninjas (Need I say more?).
