Kamen Viss, Soul of Dissent

Indestructible, flash
When Kamen Viss enters the battlefield, look at the top X cards of your library, where X is the number of creatures that died this turn.
Whenever a creature dies, you may name a card. If you do, reveal the top card of your library. If it is the named card, each opponent loses 2 life and you may draw the card.
