Thanatos, The Nine Eyed

Flying
When Thanatos deals combat damage to a player,
choose a card type. That player reveals the top
card of their library. If the card's type is the type
you chose, draw a card.
Partner with Kuru, the All-Seeing (When this
creature enters the battlefield, target player may put
Kuru, the All-Seeing into their hand from their
library, then shuffle.)
