Relentless Dracolich

Flash, flying, trample, wither
Whenever Relentless Dracolich would leave the
battlefield, instead put it into your graveyard.
You may cast Relentless Dracolich from your
graveyard without paying its casting cost, by
exiling another dragon from any graveyard.
{b}{b}: Relentless Dracolich deals 1 damage to any
target. You gain life equal to the damage
dealt this way.
