Personally, I never get hit by samus's charged B and I never hit others with it.

How about the shield move? Now that's a worthwhile timing issue to look over if you want to be really skilled at the game.

I'd have to say my overall favorite move is Kirby's drill move. It's fast, and does plenty of damage is your accuracy is good.

There is also Yoshi's and DK's spike move. A-forward in the air can help sometimes.

It's good to see someone else feeling the same way. Big isn't always good.

I also like Mario's up + B attack, when done correctly it can deal a lot of damage to the opponent. I also like to see the coins fly up.

Personally, I like Luigi's more.

Luigi's is better, Mario's coin punch just isn't strong and effective when knocking a person off the stage (unless they have 500% for health but thats a different story)

Mario's is just as hard to bring into effect too.

True. Mario is weak. Just thinking about it, I don't see how he is better then Luigi. This reminds me of a thread this forum could use...

I think that another good manuever is the roll movement. it was so cool when i first discovered to use it, then i started to use it to trick my friends a lot. all you have to do is use your shield and then move to any side while holding the shield.

The best attack is Samus' charge shot

The roll has gotten me outta many scraps and can sometimes confuse my dad.

I think the Best attacks are:
Luigi's Fire Punch- Up + B is so cool and takes a fair amount of damage done, and is fun to watch.
Link's Spin Sword Attack- Up + B is great when playing as Link especially when used near a edge.
Pikachu's Lightning Attack- I believe you press Up + B to perform this attack, when used correctly Pikachu can hit enemies on a platform above it or shock enemies near by.
Yoshi's Egg- I think you perform this move by simply pressing B but I can't be sure. This move works great when you tell Yoshi to go by the edge of the stage you're playing and Yoshi will turn your enemy into and egg and, if he/she doesn't struggle alot, he/she will plunge into the ditch.
