Brew of Cruelty

Foods you control have '{b},{t}, Sacrifice this
food: You gain 3 life.'
{1}{b}, Pay 1 life: Create two food artifact tokens.
(Foods have '{2},{t}:You gain three life.)
'A skull from the beast, to prove our cruelty.
Blood from the servant, to prove our loyalty.
And a drop of poison, just for luck.'
