Suddenly I found the best crossover.

Also if someone knows about the 'breeding seven,' those are pretty useful for helping breed IVs, but I don't remember which pokemon they are other than smeargle and shellos (?).
I've got some breeding projects with plenty of males, but I mostly work on illegal balltism. They're male though, so the ball won't pass down. I could find some hexa perfect males for you.
Off the top of my head I can think of Piplup, Zorua, Turtwig, Litwick, and maybe Aron, unless I released them.
