Hi! i really like the pokemon Golurk have a little buff, beacuse that dont have too things for make the diferences in the meta.
Some Suggestion Could Be:
*Can Learn the move Shift Gear (beacuse it doesn't useful buff move)
*Can Learn Shadow Snake
*Can Learn Mach Punch
*(this is more general) The move Shadow punch change the power from 60 to 80)
These are some of the ones that ocurred to me, i have hope you are interested. Thanks for Reading
