"Full odds" elitism is gay, unless it was caught in gen 3 you've got no way of proving it wasn't masuda'd/shiny charmed/chain captured, and even then it could be RNGd anyway. I'd rather spend a day with the Masuda method to get a shiny with guaranteed good stats/nature than spending 2 weeks hunting for the same thing with none of the benefits.
Anyway here's my Slowpoke from Leaf Green.
