List simplification:
- Torchic (max attack, speed and special attack stats, or all around good IVs with a lonely or naughty nature)
- Deino (max special attack and speed IVs and all around good IVs with a mild or modest nature)
- Ferroseed (max defense and spec defense IVs with a bold or calm nature)
- Feebas (max special attack, speed and special defense IVs with a calm or modest nature)
For starters, I can get three of the four above; Torchic I don't have in Gen. V yet, though I have a Combusken in Emerald that I will breed and import someday if I don't get one sooner.
Secondly, I have five of the six Power Items that can be attached to a flawless Japanese Ditto. This will guarantee a specific IV is maxed out for the baby (since it's flawless, everything is maxed out). Unfortunately, when breeding, you can only guarantee one IV being carried down; three are carried from each parent, so the other two are a big gamble. I also don't RNG my Pokémon; I keep it all legit.
I'll be more than happy to try getting you a Feebas; I have to still breed my Milotic (Lv.69 and Quick Balled on the first turn of the battle, woot) to give me a "caught" Feebas, so this will give me that. I can breed until I get a calm or modest one. Of special attack, speed and special defense, which is most important? As long as it's not the missing Power Item, I can guarantee it being maxed out, but the rest are by chance. Same question for Deino and Ferroseed and same ability to breed until the right nature hatches.
