Monster

When Monster enters the battlefield, create 3 1/1 black snake tokens with deathtouch.
{x}{x}{g}{g}{b}: Monstrosity {x}. (If this creature
isn't monstrous, put x +1/+1 counters on it and it becomes monstrous.)
When Monster becomes Monstrous, gain Infect.
"A fitting title for one who revels in the death of humans. One wonders how Lucius befriended her."
