Eye Sliver

Whenever a Sliver you control deals combat
damage to a player, each player puts the top card
of their library into their graveyard.
"The creatures were vicious, fighting with no
expressions of pain, anger, or fear, and inflicting lethal wounds. But when this one arrived, they all grew eyes,
and their mere stare shattered our morale. The men
who are worst off have lost almost all comprehension,
but they all remember one thing; to fear the slivers."
—Tork Renault, Zavel Guard
