I just got Warrior Z, making a full 20 Rare Breeds collected! =D
I'm quite excited. ^_^ There are 42 rares for the released Families in game, of these 42 we know of and have access to 36 of them. There are 6 Rare breeds we do not have access to. One for Tiger, one for Mew, one for Suezo, Two for Zan, One for Piroro.. of these we only have knowledge of what the one for Suezo is (Sueki Seuzo). So I have over half of the available rares, and just under half for all the rares including the unobtainables.
I'm feeling kinda good about my collection now. =3
