Smash Lord
Sheik's metagame has come on in leaps an bounds, mostly in the ways of kill setups and what her true combos are. Her attack speed and low knock back on some moves has set up a bunch of combos with the right decay. People are also getting better at keeping the Ftilt decayed enough for Ftilt => U smash tipper, which kills pretty early. She also has the GRUST on any characters she can force an air release on, which again can lead to sub 100% guaranteed (I think) kills on MK from a single grab, which is not improbable due to Sheik's speed.I don't see Sheik moving more then one spot.
Zelda going down? Sure. Sheik moving up a bunch? Not before Sonic.
