(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I: You may sacrifice a creature. When you do, Kardur's Vicious Return deals 3 damage to any target.
II: Each player discards a card.
III: Return target creature card from your graveyard to the battlefield. Put a +1/+1 counter on it. It gains haste until your next turn.
