Paying a Sacrifice

[Achtung Panzer]

So when the ZP plays a Sacricfice card and needs to give up 2 cards in total, does this include the Sacrifice card itself or discarding two other cards from the ZP hand to play the Sacrifice card?

I guess discard 2 cards and then play the Sacrifice card, but wanted to check.

In addition to the card itself. Some sacrifices are killing zombies, or having heroes draw cards instead.

[Zinthos]

Definitely two other cards.
