User blog:SoMaShadow/Power of Yu-Gi-Oh cards

As someone who hasn't watched Yu-Gi-Oh seriously, I'm not sure of the overall power that the cards can hold. I understand that there is a lot of soul hax and similar related things (Luck/Probability manipulation) and if anyone could give me a rough kind of power level that the monsters can have.

I'm mostly aiming for Duel Monsters based cards (Winged Dragon of Ra, Silpher the Sky Dragon, Exodia) because using Yugi/Yami seems interesting and I have an opponent for him, but you'll just have to wait and see.

Thanks
