Duplicates can be discarded in stead of the unique card it is attached to, in the case that the unique card would be discarded, killed, or returned to hand. Does that count also if you have a duplicate on a card that is being discarded for a cost?

The reason I ask is for Rhaenys's Hill. Say I have two in my hand, should I attach Rhaenys's Hill with a duplicate for free, and then have two "charges" of it's effect. Or is there a rule stopping this? That'd be pretty cool if the dupe trick worked, but I have a feeling it wont. In any case, the situation comes up with other cards as well, I'm sure.

So how about it? Dupes as cost?

Absolutely not.

When you save something, it has never actually been killed, discarded, returned to hand or whatever. So if you discard the Hill to pay a cost, then save it, you never actually discarded the Hill. If you never actually discarded the Hill, you didn't pay the full cost of the ability. If you didn't pay the cost, you do not get the effect.

Hi you can play a dupe on the Hill for free but it would be for nothing. The thing is that the effect on Hill has a cost - kneel and discard. SO if you want to use the card you have to pay its cost. If you would save it with dupe the cost would not be payed and thus you would not be able to get to the effect.

That was a silly oversight >_<

Thanks.
