The Pokémon Breeding Legend (Part 1)

I've got a Pokémon breeding program that has given me some great results. Every one of my trained Pokémon has a 30-31 IV in their two most ideal stats, and high 20's in every other stat that matters. They perform like gods in battle. What's an IV...? Having a 31 IV means the Pokémon has the highest possible base stat. Can make a difference in a tough spot, especially in speed.

I've kept this to myself since the summer, but now I'm willing to pass on the love to you. However, at this time I'm only offering these 6 Pokémon...
Eevee, Totodile, Staryu, Elekid, Gible and Porygon. The superb IVs of my expertly bred Pokémon have a very high chance of being passed onto the eggs I will make. However, I'm making no promises.

To the untrained eye, these are just 6 Pokémon. However, take into consideration that Eevee has 7 possibilities for evolution, Totodile is pretty hard to come by, and Staryu and Porygon are a HUGE pain in the nuts to breed for IVs. Trust me, they WERE.

What do you give me? A battle. Win or lose, I'll give you an egg of your choice. I can guarantee natures and most Pokémon will come with egg moves. You just tell me the type of battler you intend the Pokémon to be, (sweeper, tank, etc.) or in the case of Eevee, the intended evolution. As a bonus, I'll throw in an item for anyone who defeats me in battle.

If you have any questions, do let me know!
