One day I was playing Pokemon and decided to raise my Smeargle (from AR) a few levels. I grew it to lv.50 and all it knew was sketch with 1PP. So I went into the wild and used smeargle. The wild pokemon used mud sport, then I used sketch.
Next turn it was replaced with mud sport! I thought it was a move like mimic so I left the battle, checked it's stats and all it knew was mud sport! so my point is, is my Smeargle going to be stuck with 1 attack as weak as mud sport?
