Even though Dialga, Palkia and Giratina can learn the move Heal Block via level up in DPPt (Source: https://bulbapedia.bulbagarden.net/wiki/Heal_Block_(move)) but when I created this Palkia from pokemon Pearl with the move Heal Block, PKHex said it is illegal cause of an invalid move. Same things applied for Dialga and Giratina since Heal Block isn't highlighted as a legal move for them. Heal Block Pearl Palkia.pk7
