No. So far the DS Emulator is still in development so as of yet, there is no possible way to connect to either the GTS or WiFi.

you have to get a pokemon such as Golbat or some other flying pokemon that can learn it. i know this is true because i have gone against golbats that know air slash and i have one too
Double hit x scicor nightslash and faslswipe or slash
Go to pastoria talk to the move tutor and give him a heart scale
I think night slash because more Pokemon can learn slash but few can learn night slash if it weren't a TM
It learns slash at level 28 I think
First, do not evolve your sneasel, second, find a heart scale, third go to the move relearner's house. Give him the heart scale and select your sneasel to relearn night slash
blaziken. if you want to have it as strong as possible, make it lern these moves: Fire Blast Blaze Kick Fire Punch Slash
Go to route 228 south of Stark Mountain, they are fairly common there.
