Ezotl, God of the Dead Sands

At the beginning of your end step, create a 2/2
black and white Zombie creature token.
{1}{w}{b}, {t}: Choose a Zombie you control and
another creature other than Ezotl. The chosen
Zombie gains all abilities of the other creature.
Then if you control five or more zombies, you
may transform Ezotl, God of the Dead Sands.
