Why in duellinks, my opp have only two card. Nothing in hand and this card with grave curse on field and he can activate this card? Am I misunderstood that you must remain 1 card in hand and one on field at least? He already set this card too so even include itself is not enough. Misprogrammed??
Add that he draw grave curse this turn and summon and activate sanctity. I didn't econ that grave even though I expect it to be this card because it should not meet condition.
No. As I say he has 2 card on the field. And even though card of sanctity is in hand itself, it is not count. But he already set it before too so it's surely not counted. I found the error cause now. Duellinks en card text follow TCG but real effect follow OCG (Japanese). Other game such as YGO 5ds also conflict like this.
Ref: http://yugioh.wikia.com/wiki/Card_Tips:Card_of_Sanctity
In the TCG, you must have at least 1 card in both your hand and your side of the field to activate "Card of Sanctity". In the OCG, you only need 1 card in either your hand or your side of the field to activate it.
think about it, if you have 2 cards in your hand and you played this card, it only means it itself satisfied the other condition since you will have to put this card it face up position on the field when you activate it
