Graft, The Last Voice

Afflict 8
Whenever Graft deals combat damage to a player, that player sacrifices a creature.
At the beginning of your upkeep, each opponent loses X life, where X is the number of enchantments in your graveyard.
{9}{b/r}{b/r}{b/r}: Return target enchantment card from your graveyard to your hand. This ability costs X less to activate, where X is the number of enchantments in your graveyard. Activate this ability only if an opponent has lost 8 or more life this turn.
