A Thousand Hands

You may pay 1 life. If you do, each opponent sacrifices a permanent with converted mana cost 1, reveals their hand, and discards a card with converted mana cost 1. Repeat this process for 2, 3, 4, 5, 6, and 7.
"At first, I saw a small hand lurking down an alley. Now, I can't even escape them by closing my eyes."
