Card of the day - Sandra Trueblade

[Shadow Era]

Currently there is only one type of resource that you get by sacrificing a card from your hand. However in the future there may be special resource cards.

If your opponent doesn't currently have any resources, well then you can't choose a resource to destroy. If this is the case when you play this card, then the ability will do nothing.

She's an ally, so you can still attack with her after her ability is used.

[Mahasuke]

Or it may be possible to return her to your hand to replay her again, causing your opponent to have to take two more cards out of his hand to play as resources
