Sorry, I came on with the wrong Poliwag, ill be right back on
Here is the only flawless ability one Adamant method K spread
2808825660F a777c735 (ADAMANT, ability 1) 31/31/31/17/31/31 (Seed: e0090210 Frame: 6704) HP DARK 59
Now this is for the typical 490-590 HG/SS delay, so if you want a lower frame youll have to search for the seed on a higher delay (you can use PokeRNG for that, the link to PokeRNG is in one of the posts in the RNG thread)
