Myrddraal

({p/b} can be paid with either {b} or 2 life.)

Deathtouch, indestructible

When Myrddraal enters the battlefield, for each {b}
spent to cast it, create a 1/1 black Trolloc creature
token with "When this creature dies, each
opponent loses 1 life".

When Myrddraal leaves the battlefield, sacrifice all
Trollocs you control.
