If I recall correctly, every character can DACUS, it's just more usefull for some than for others.Captain falcon can DACUS? I thought you just run and use up-smash for him. And what do you guys do when faced with a metaknight? This has stuff to do with falcons metagame because metaknight is like 30% of the metagame and its good to discuss countering him.
and for meta knight, it's a very hard matchup >.< almost all of your moves can be punished by him easily, and it's hard to find an oppening to attack.
I'm not too familiar with this matchup, so I hope someone else can provide more indepth info.
or you could wait till meta knight is discussed in the matchup discussion thread
