Corrupted Dominator

Tribute 4 (As this creature enters the battlefield, an opponent of your choice may place three +1/+1 counters on it.)
When Corrupted Dominator enters the battlefield, draw cards equal to its power. If tribute wasn't paid, gain control of target creature for as long as you control Corrupted Dominator, then each player sacrifices a creature.
The power of the Ancients still pulses in blackened veins.
