that looks like the one you answered on its movest the other day
;) -defintly keep drain punch and dragon dance maybe use ice punch instead of head smash covers fly and you dont loose hp
maybe also add a dark stab or fake out
i also suggest changing your item to something like muscle band or leftovers
Excadrill 
i would use swords dance instead of hone claws seen as all your moves have full acc appart from drill run which is still 95acc so swords dance would be my choice also maybe swap poison jab for something like metal claw which has good power with swords dance also can raise atk

sorry about the litwic image i think its better looking
so all looks good though flamethrower is more reliable but rest is good
