Undead Dragon Lord

*Flying, Trample, Deathtouch, Lifelink.
*All flying and Zombie creatures you control get +1/+1 and vigilance.
*When this creature kills another creature, put a 2/2 Zombie creature token onto the battlefield.
Only the most experienced Plague Alchemists can bring back big creatures, but that comes at a price, including their supplies and , sometimes, their lives.
