I never understood the "breeding for 6 IV" meme that injectors keep on saying. Don't you only need 5? Foul Play isn't that common, and physical attackers don't need the special attack IV. There are mixed attackers and Hidden Power I guess, but mixed attackers are generally bad, while Hidden Power is usually a niche pick or for stuff with bad movepools, or run on unbreedable things. Pic related is the only breedable thing that I would run Hidden Power on, but even then, it fights with Giga Drain for a slot. It doesn't take more than 20 eggs (15 min of hatching) for me to actually get a perfect 5 IV Pokemon, so I never understood the time meme either, but that could just be my luck.
