Smash Master
Learning how to do Shieks Sliding up Smash is much more difficult than other characters (Snake, Link, Wario, etc...). Shiek Slides alot even on a regular dashing then upSmash. I Play with the Wii Remote and Nunchuk, so I set my upSmash and DownSmash on the D-Pad. So the easiest Solution for Getting this downpacked is to go to Training mode and Alter the Speed by pressing start to bring up the menu. Start off with the slowest speed 1/4. Then Generally work yo way up until you get back to the normal Speed. This will allow you to recongize her motions and the correct time to press the up smash on the D-Pad(c-stick for GC Controls).
For Those Who are new to these techniques...you start off by Running then pressing A(or whatever you use to attack normally) Slide your thumb from A to Up Smash(Note: I'm referring to the Wii Controller since thats what I use) in a liquid motion. It's easier to Slide your fingers from button to button. You should notice Shiek Sliding an abnormal amount of distance. It's quite difficult to pull off even with the Speed altered. So Good Luck!
