I bred a Timid, HP Fire, 31/xx/31/30/31/30, protean Froakie, inside of a net ball, and I hatched it in the Flood Chamber so it shows it in the summary screen. And I did this without instacheck. :) Sort of. Yeah, I know. I'm totally bragging right now. And yes, I want some attention. It took many hours of my life to do this. Ask me anything.
Don't get me wrong. I would have used instacheck, but then it got patched two days before I was going to start the breeding process. Luckily I had checked which of my pokemon had IVs of 30 so I could breed them onto Froakie. So I did use instacheck a little bit for that. But not to check Froakie eggs as it was patched by then. I didn't let the patch stop me from trying. And now I have my own perfect Froakie. The attack IV is a 6. I tried to get a 0 since this is a special sweeper but the RNG was not on my side. I managed to breed some with an attack IV of 1, 2, 3, but couldn't get a 0. I ended up settling with this one.
I spent 3-4 hours a day breeding for a whole week to get the first perfect HP Fire spread. Then another day or so to try and get one with a 0 attack. By the end of this I felt I would NEVER breed for a perfect Hidden Power spread ever again. I didn't even want to play pokemon anymore. lol. But I'm back now. If there is enough interest, I can make a guide of my process.
Honestly, after instacheck was patched, I just wanted to see how far I could get before I lost my mind. I wanted to overcome the breeding mechanics set by Gamefreak just to say I did it. And well, I did it. But I won't ever do it from scratch again.
