Aangrunax the Demanding

Flying Indestructible
When cast, target X creatures you control with combined power and toughness X or less. Put a
Head counter on them.
Aangrunax the Demanding's power is equal to the total power, and toughness equal to the total toughness of creatures with Head counters on
them.
Creatures you control with Head counters cannot
be controlled by your opponent.
To puppet an entity already fueled by greed
was simple.
