Polyphemus, Blind Cyclops

At the beginning of your upkeep create a 2/2
white Sheep creature token.
Sacrifice a sheep: Create a Food token (It's an artifact with "{2}, {t}, Sacrifice this artifact: You gain
3 life")
Sacrifice five sheep: Create Golden Fleece (It's a Legendary artifact token with "If an effect would
create one or more tokens under your control, it creates
twice that many of those tokens instead.").
