Hi, today I managed to a demon hunter card from doing adventure mode. The card has an effect saying something like "Sacrifice1: Play a spell from hand". I've not seen Sacrifice before as I mainly play witchblade or World tree. What does it mean by sacrifice is it just a discard or draw 1 less card? or is it a payment in health?

"Sacrifice: You can discard the number of cards indicated to activate the effect. You will draw the same number of cards less on the next turn."

This is in the keyword explanations you see next to your cards (If you deactivated the help, you can reactivate it in your account settings).

about sacrifice boadicea, are some plans to change it? very few persons use this skill cause of its many disadventages...
