Which move from any character do you spam the most?
Ice Climbers' Blizzard since that's their main key on winning against a few characters like MK. =D Kirby's b-air because it's a spacing key for him to win. It also hits directly and it has great range.
Sorry....starfire_jirachi. Be careful for what I and Ota were doing PK tech. I often followed his lead xD. Unfortunately, Metamence(MK) tried to avoid us from PK...then failed. We used PK thunder to turn into a cross. Ota only main Ness.
Koopa hopping is a technique that (I think) can be applied for all characters. If it can be used by all characters, however, Bowser can do it much more easily or noticeably, hence why his Japanese name is used to describe it. Basically, coming off of your first jump, just before you hit the ground, you use forward B and then jump. If used correctly, you will immediately go into the second jump, and if you continue to perform it correctly, you will be able to use your second jump for as long as you want. It's a great way to get out of landing lag, especially for Bowser.
OK, I'm home right now, and I'll be able to Brawl anytime tonight or tomorrow. But Sunday, I'm gone again. If anyone wants to Brawl me, there ya go.
EDIT: So it's FORWARD B, NOT forward Aerial! No wonder I've been screwing it up >_<.
Aaaah.....I know that about Luigi; yeah it's working for his down-B(tornado).
His side-B is nope. Depends on his down-B is easy to avoid from projectiles or items(I think). I often play as Luigi as many times.
It also works on Kirby's Hammer after he uses all of his jumps.
This works for all characters' certain aerials that are quick when they are auto-canceled. Such as Pit's n-air, when you auto-cancel his n-air and start to land, you need to jump at the right timing, which is hard. n-n One unique thing about this technique is that I THINK Peach is capable of floating again after auto-canceling her d-air.
Edit: Sonic Boom's right too, but it works mostly for the casts' aerials, and some of the casts' specials.
Hmm... I'm up for some brawls and warm-ups, for not playing Brawl for months. ;-; sadface
