Rime-Grip Draugr

Ward {3}
When Rime-Grip Draugr enters the battlefield,
search target player's library for any number of nonland cards with the same name and exile
them. Then that player shuffles. That player may
cast those cards for as long as they remain exiled.
Whenever a player casts a spell they own from
exile, that player loses life equal to twice that
spell's mana value.
