Gwehhg

When you cast Gwehhg, each player sacrifices all nonland permanents he or she controls.
At the beginning of your upkeep, choose target nonland permanent in your graveyard. Return
that card to the battlefield under your control
with a dread counter on it. You lose life equal to
it's converted mana cost.
If a dread counter would be removed from a permanent you control, sacrifice that permanent.
