Messis, Scion of Departure

Flying, deathtouch, lifelink
Whenever a creature dies, add {w}{b} to your
mana pool. This mana doesn't empty from
your pool at the end of turns or phases as long
as you control Messis, Scion of Departure.
You can cast creature cards from your graveyard.
They say death is an inevitability, but that doesn't
mean it's the finale. There's always someone willing
to make an exchange.
