I've seen a lot of people say scyther's swords is worthless cause it can do
60 damage i two turns anyway.  Well there are some situations where using
swords dance is better, for example; your scyther vs a kingler which has 60
Hp. If you use slash on it, KLingler can do flail on you and you suffer
damage, but if you use swords dance and then slash, it can't use flail and
it will die on your next turn.        
Another example your facing a poisoned pokemon who will die on its next
turn(i.e Charizard has 11 damage counters on it) use swords dance and do 60
damage to your next opponent instead of  30 damage.  So to wrap things up,
scyther is one of the stronger pokemon you just have to know when to use
its power
