Benson, Spoiler of Employees

When Benson, Spoiler of Employees enters the battlefield, choose two opponents.
{t}, {x}: Chosen opponents each receive X poison
counters. Then double X. You lose that amount
of life.
"You both have done such a good job today. Don't see
why you couldn't give yourself a little reward, right?"
