Killer Service [Murders at Karlov Manor Commander]

When Killer Service enters the battlefield, create a number of Food tokens equal to the number of opponents you have. (They're artifacts with "2, T, Sacrifice this artifact: You gain 3 life.")

At the beginning of your end step, you may pay 2 and sacrifice a token. If you do, create a 4/4 green Rhino Warrior creature token.
