Malevolent Seer

Ally Offering (You may cast this card any time you
could cast an instant by sacrificing an Ally and
paying the difference in mana costs between this and
the sacrificed Ally. Mana cost includes color.)
Whenever the creature offered to Malevolent
Seer or another Ally you control dies, you lose
1 life and draw a card.
They're not allies. They're ritual fodder.
