The title is self-explanatory. I'm going to attempt to make a goat-based or deer-based Pokemon sprite, except my mind is blank. :P
All forms of Deerling
All forms of Sawsbuck
Others:(these kind of resemble Deer/Goats)
Hope I helped!(ish)
Source (just looked at every Pokemon that resembled Deer/Goats)
There may be more, but I'm just going from memory.
As far as I know, that's it.
