DMU-87 The Cruelty of Gix

Read ahead (Choose a chapter and start with that many lore counters. Add one after your draw step. Skipped chapters don't trigger. Sacrifice after III.)
I - Target opponent reveals their hand. You choose a creature or planeswalker card from it. That player discards that card.
II - Search your library for a card, put that card into your hand, then shuffle. You lose 3 life.
III - Put target creature card from a graveyard onto the battlefield under your control.
