...What's the point of a ditto evolution?
Erhm, it's bigger, it's slightly faster, and it has slightly more HP. Other then that though, It isn't that different from Ditto.
Also, Mewthree=No, the name sounds silly, and the only way they would make it work is pulling a Scizor and relocating Mewtwo's stats.
Luvdisk is garbage, but I honestly can't see anything to make from it. Put three Luvdisk together?
Delibird is the gimmick bird of the second generation, and is supposed to be sub-par, so it matches with Chatot and Farfetch'd (who also don't need evolutions.)
