Nice. I have a total of 3 Vaporeon, 3 Jolteon, 2 Flareon, 2 Espeon, 2 Umbreon, 2 Leafeon, and 1 Glaceon. Plus I've traded at least 2 Eevee and a Glaceon to other people. That makes 20.
And one of each eeveelution is at level 100.
But I don't just focus on eeveelutions- I also have a lot of legends. Zapdos, Moltres, Articuno, Mewtwo, Registeel, Rayquaza, Mesprit, Cresselia, Palkia, Heatran, Giratina, and Deoxys, all of which are non-hacked. I also have a hacked Darkrai, Shaymin, and Arceus. Thats 15, although I may have missed a few.
