Gwyn, the Hollowed King

If one or more Soul Counters would leave the battlefield, you can pay {1}{b}{b}{r} to put
Gwyn the Hollowed King from your graveyard to
the battlefield under your control and put those
Soul Counters on it. If you activated this effect,
exile Gwyn
the Hollowed King when it leaves the battlefield.
When Gwyn enters the battlefield you may
draw Xcards and take X damage, where X is the
number of Soul Counters you control
