Harbinger of Desolation

Hellbent — If you would draw one or more cards
while you have no cards in hand, put that many Desolation counters on Harbinger of Desolation.

instead. You may cast those cards for as long as
they remain exiled and as long as Harbinger of Desolation has five or more Desolation counters
on it.
