Well I got the Weavile from godudette, drcossack just tutored Low Kick on it for me. I think it was that it was in a Cherish Ball and had almost flawless IVs. He asked me how I got it and I said a friend RNG'd and I asked him if that was illegal (it's not) and he seemed okay with it.
Also dude, how are you able to do the same seeds over again? Because I found some really easy shiny seeds. Like this jolly one I found only requires 36 happiness taps and 6 coin flips, and it worked dude!!
