Oblivion's Grasp

Kicker {1} (You may pay an additional {1} as you
cast this spell.)
Each player sacrifices X creatures, where X is the amount of creature cards in that players
graveyard. If Oblivion's Grasp was kicked, exile
all cards in each opponent's graveyard.
"Sure, vengeful spirits are scary. But the ones you
should really worry about are the desperate ones. The
ones that reach out, just to pull you down with them."
