ssbm king

I hadn't played this game for a long time until recently when I saw a guy making an awesome trick with Link. He mysteriously digged out a huge sword from the ground and his power and reached increased enormously.
I've been trying to figure out how he performed this trick, but haven't found a clue. Does anyone know how to do it?

I've heard there's also another trick where you can play as zelda and shiek at once (you control both player at the same time).

all those ppl out there that wanna know about the link thing: ive got the answer! when playing as link do the move were you put your sword in floor(i think its down and a/jump down and a)on a metal box and then you turn golden!im not sure if its true cos ive never tried it but i also heard it can be done with gannodorf as well
