As a shiek player i have noticed one flaw in shiek. she cant kill. i dont no if anyone else has noticed but at a certain % when you f-tilt a character they will end up directly above shiek. when they are above shiek you can do an up-smash to finish them off. however when u up-smash you must hit them with the top part of the up-smash because that is where it is the strongest.this can kill most character when they are at 100% or even below 100%. i have done this on my friends many times so i think u cant DI out of it if u get them at the right %. im sorry i cant get any videos of this because i dont no how and i do not have the proper equipment. i hope this helps many shiek players.
