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.
