Exdeath, Void Warlock's last ability checks your graveyard at the moment it would trigger to see if you have six or more permanent cards in your graveyard
At the start of the end step, she can also return one target enhancement card from the graveyard to the battlefield with a finality counter on it, mirroring her ability to send spirits to the Farplane
Once again, the mana investment for this card is huge, but since it wins the game upon resolution, its definitely worth it
Still, with those abilities and just to add to that a pretty impressive 8/8 in Power and Toughness, this is definitely a card thats worth waiting to get into play
Then if you control eight or more artifacts, each opponent loses life equal to that card's power
