Elias, The Herd's Vengeance

Lifelink
Whenever you receive damage from an
opponent, reveal cards from the top of your
library until you reveal a Curse card. Put
that card onto the battlefield attached to the
player that dealt damage to you. Elias, The
Herd's Vengeance deals damage to that
player equal to the converted mana cost of
the Curse card revealed this way. Shuffle all
other cards revealed this way to the bottom
your library in a random order.
