I think it’d be great to link species collection threads in the top post! It’ll give us a nice central place to see what species have been covered. I’m sure Eeveelutions will be the most crowded 
My Hoppip/Skiploom/Jumpluff collection thread is here
I’ve just been getting small bits and pieces in here and there, but I’ve put aside some money for my first ZenMarket order. I’m excited to try it out! But am also taking my time to make sure I’m fully aware of how it all works. Once I feel good about it (and have some time to browse the Japanese marketplaces), I’ll hopefully be ordering a bunch of stuff to start filling out the Japanese side of the collection (of which, I only have one set card so far)!
