Matthew, Sorrow's Gift

Whenever a non-land card enters your graveyard from anywhere other than the battlefield, you gain 1 life, and each opponent loses 1 life.
You may cast creature spells from your graveyard by paying life equal to its mana cost in addition to paying its other costs. Creature spells cast this way enter with a finality counter on it.
Whenever a creature you control attacks, it connives.
There's a storm brewing.
