My favourite RNG abuse from 2012 would either have to be my first 4th gen RNG, the Moltres in my SS that Gonzo helped me RNG. It took a while, but I finally got it. Or maybe the Vaporeon (oh well Eevee) that I RNGed for a challenge. Just because it's my favourite Pokémon.
Welcome back, Vappy -- you were missed! I hope to see you around chat and everything some more.
