Grim Visions

If you lost life this turn, scry 4. Draw two cards.
You may cast this spell from your graveyard if
you tap four creatures you control in addition its
other costs. If you do, exile it as it resolves.
"I have seen a dark future ahead, one that I am
afraid will come to pass. We must win this war to
prevent this calamity, no matter the cost."
