Honestly... I'm not sure why it works. It just works, incredibly well even. I have no clue why. It sets up every time the way I said, and somehow comes out on top every match. Lol. It is very strange, it doesn't make much sense on paper, but it has heart.,. And idk why, but it works really well. As for Giratina, that's a stone edge after two shell smash, stealth rock damage and sandstorm damage.
