Finally, after one week trying over and over, intense Narcissa is finally defeated. Anyways, guys, is the time flute the only wat to purify shadow pokemon? LIke... I have a lot of them to purify and I don't know how
Shadow Pokemon in center, with regular Pokemon around it. It's best so that the Pokemon next to it is super effetive against it, so the purification goes faster. Then just walk around and wait, until a message says that your Pokemon is ready to be purified.
