Typhus Pox Lord

Every time a creature is sent to the graveyard, create a 1/1 Poxwalker Zombie creature token under your control.

If Typhus Pox Lord leaves the battlefield all Poxwalker Zombie creatures are destroyed.

When you have 3, 7 or 21 Poxwalker Zombies creatures under your control, all Poxwalker Zombie creatures gain +1/+1 and Deathtouch.
