I can get you one. Do you have any sword exclusive mons, or baltoy?
I went on a Wishiwashi expedition when I first saw your post and tried catching on for over two hours, then I gave up and traded for one. I didn't realize it had such a low catch rate or I never would have Surprise Traded my other. I can touch trade you if you still need it just shoot me a link code and tell me your IGN.
No worries I am a little bit late myself, I am about to search for that code please set it again.
