Yugioh GX opening 4 with Ryuusei no Rockman


Demon King/Sith Warrior
I wanna make a ryuusei no rockman AMV with the 4th opening of yugioh GX, precious time glory days by psychic lover. I have the game and there's alot of sad scenes so I'd think that the anime is kinda sad too. Does anyone know what episodes I should download for action/sad scenes?
