Yeah, I know for a fact that Dew's shinys are legit, cause I've traded with him numerous times, and I'm sure he can say the same for me.
We get them quick cause 1) We know what we're doing, and 2) we trade them for shinys we DON'T have, therefore increasing our collection.
Dew, ill take the larvitar. you wanted the nidorans (both male and female) and caterpie?
