You both played quite well. The Falcon (Rob) did an excellent job of using the shield to block your recovery, but he should know that he can meteor cancel out of marths dancing blade. He probably does know that but since the >B meteor is rarely used, he probably didn't expect it.
You (Den) did well also, but my critique would be that you used forward smash in a couple of bad spots. Like, a one time you got smash happy and tried smash him like three times in a row and he got you with an aerial the last time you missed. Also, that charged forward smash was bad but you were fortunate that he didn't hit you. Finally, you seemed to be full jumping a lot. I don't know if you were trying mind games or what but one time you did it and when you finally landed you got raptor boosted by him which could have turned into a combo real quick. Also, when he had his back to the tree, you kept full jumping when you could have just grabbed him. Overall though, you both still played well.
