Threnody of Thrawn

The second time one or more cards are exiled from anywhere each turn, you may sacrifice an enchantment at random. If you do, choose one—
• Each player sacrifices a creature.
• Exile a card at random from your graveyard. Then, each player returns a card they own in exile to their graveyard at random.
