Endlessly Screaming Shield

Equip {1} — Equipped creature has +0/+2.
At the end of your upkeep all players put the top
3 cards of their library into their graveyard, and
then put the top 2 cards of their library into
exile. Until the end of turn all creatures loose
vigilance and whenever a player takes an extra
turn or extra stage they loose 1 life.
The shield had been such a stupid idea, what was
that the wizard had said, that it'd be impossible
to wear, to wield.
