Shiek players... edge tech... lmao...
But seriously though, just recover like u normally would and watch ur opponent. Let's assume there is a Marth waiting to do a f-smash. Just do ur ^B and hold down 'R'/'L' like u would with a space animal, then when u see the Marth do the f-smash, just do the smash DI and ur done (smash the joystick in the direction of the edge during the actual "hit stun" of the f-smash). Wall jump into a ^B ledge stall after that for maximum sexyness... and looks of disbelief...
Usually you have a good opportunity to edge tech after the second "boost" of ur ^B. The part when ur face is shoved against the ledge, but you have to wait for Shiek to grab the ledge, and at the same time u no longer have ur invinsibility frames (ie. u use the second "boost" of ur ^B to "run into" the ledge). So yeah... this paragraph was hard to explain...
