YGOPro is an automatic dueling system made by chinese programers..Yup,that's right,no more applying the effects manually,no more substracting your own life points,it's all automatic.
The game doesn't have TCG exclusives (no Tour Guides,Reborn Tengus,etc) but it does contain many cards including the new monsters from Order of Chaos.Also it follows the OCG rulings.
