Forum:Im confused...

Why some OCG and TCG rulings contradict each other?

Per example:

In OCG Necrovalley negates any effect that affects another card in the Graveyard, regardless of whether or not it targets, but in TCG Necrovalley only negates cards that target a card(s) in the Graveyard.

In OCG Crystal Seer´s effect forces you to show both cards to your opponent, but in TCG you do not reveal either card to your opponent

Why does this happen? Are supposed to be the same cards and therefore have the same effect... Why their rulings are different?

I am confused because i dont know which ruling i will follow (specially about Necrovalley because im running a flamvell deck right now)
