Magecraft — Whenever you cast or copy an instant or sorcery spell, each opponent loses 2 life and you gain 2 life.
[+1]: You lose 1 life. Look at the top three cards of your library. Put one of them into your hand and the rest into your graveyard.
[-3]: Each opponent sacrifices a creature with the greatest power among creatures that player controls.
[-8]: Each opponent may discard a card. If they don't, they lose 3 life. Repeat this process six more times.
