Vecna, the Whispered One

At the beginning of your end step, you may sacrifice an artifact, creature, enchantment,
land, or planeswalker. If you do, each opponent
may sacrifice a permanent of their choice that shares a card type with it. For each opponent
who doesn't, that player loses 2 life and you
draw a card.
