Basically, your Trainer ID isn't everything; for a pokemon to belong to you, it's ID, SID, and OT all have to match with yours.
In other words, it's impossible for me to make the pokemon belong to you, as that would require me to know your ID and SID. Which I don't. And besides, I already finished the codes; can't really edit them now.
What made you think that? All you have to do is breed a male tentacool knowing barrier with a female corsola to get a male corsola. Then teach that corsola recover through level up and breed it with a female lileep for a lileep with barrier and recover. I taught it swords dance and rock slide through tm.
Please do check all possiblities before accusing me.
