I just had a bunch back when I was farming for leftovers via pick-up (and people were asking for an arm and a leg to clone stuff).
I forgot Pickup was a thing. Might start carrying around a Zigzagoon when EVing then, might save myself some effort.
Just checked your wants list, I may be able to do shiny Ponyta in a Heavy Ball and a shiny Inkay in a Nest Ball.
It is down as one of your regular wants though. Wanted to mention it in case you wanted a fancier version.
