What is a doubled effect of Intrigue, Scepter of summoning or Necropolis?

It's not very likely to be in your hand after Necropolis. ;-p

My guess is that it's supposed to do nothing in such a case.

Either way, it's unlikely that this card will be implemented, since we don't support cards that use effect of other cards.

Btw what does this card when played twice in row?

*2^2

Saw that coming :P

True, true, it needs change...

I think you forgot stock.

[Progressor: Removed redundant quotation]

yes, such powerfull mage like Elminster can easily double your stock effect :)

Please note that such effect would need to get the information about stock, wall.. from the changes data (small numbers). This means it will double not only the effect of the last card, but the whole chain (when quick and swift cards are played). It is impossible to separate the effect of the last played card.

And I forgot you forgot facility's also.

too bad...
I must to find new job for Elminster

How about:
Changes Stock, Walls, Towers, Facilitys of all players by the double negative value of the changes in the enemys Round.
Ok, maybe it would need some changes or a cap, at least.
Another idea would like to be like this (Dont know if it could be implemented):
How about:
Changes Stock, Walls, Towers, Facilitys of all players by the value of the changes in your last Round.
